Summary of Contents

• Page 1: User's guide for the STCP multiple programming electronic thermostat for heating floors. The product has been slightly modified since its introduction. To obtain the guide corresponding to your model, please contact customer service. For further information or to consult this guide online, please visit the website.
• Page 2: Warning Before installing and operating this product, the owner and/or installer must read, understand and follow these instructions. If these instructions are not followed, the warranty will be considered null and void. The following instructions must be adhered to in order to avoid personal injuries or property damages. All electric connections must be made by a qualified electrician, according to the electrical and building codes effective in your region. Do not connect this product to a supply source other than 120 VAC, 208 VAC or 240 VAC. Protect the heating system with the appropriate circuit breaker or fuse. You must regularly clean dirt accumulations on or in the thermostat. Do not install this thermostat in a wet location such as a bathroom. When a part of the product specification must be changed to improve operability, priority is given to the product specification itself. The actual product and packaging, as well as the name and illustration, may differ from the manual.
• Page 3: The STCP electronic thermostat can control heating floors with electrical current ranging from 0 A to 16 A at 120/208/240 VAC. It features an easy user interface and maintains room and floor temperatures at a requested set point with high accuracy. Floor mode is the factory setting, ideal for maintaining a hot floor even when ambient air temperatures are high. Ambient mode can be activated by pressing the A/F button, providing stable air temperature without fluctuations, suitable for large, frequently occupied rooms. Factors affecting ambient air temperature include large windows and other heat sources like central heating systems or fireplaces. The thermostat ensures uniform temperature in such cases. This thermostat is not compatible with electrical currents higher than 16 A, inductive loads, or central heating systems.
• Page 4: Parts supplied include one thermostat, two mounting screws, four solderless connectors suitable for copper wires, and one floor sensor. The thermostat must be mounted on a connection box, approximately 1.5 m above the floor level, on a wall section free from pipes or air ducts. Avoid installing the thermostat near windows, external walls, or doors leading outside. Do not expose the thermostat directly to sunlight, lamps, fireplaces, or other heat sources. Ensure the thermostat is not close to air outlets, concealed ducts, or chimneys. Choose a location with good air flow, avoiding areas behind doors or where drafts are frequent. Refer to the installation guide of your heating floor for sensor installation. Cut off power supply at the electrical panel to avoid electric shock before installation. Ensure the thermostat is installed on a junction box located in an uninsulated wall. Keep the air vents of the thermostat clean and free of obstructions.
• Page 5: Using a screwdriver, loosen the screw retaining the mounting base and front part of the thermostat. Remove the front part of the thermostat from the mounting base by tilting it upward. Align and secure the mounting base to the connection box using the two screws supplied. Route wires coming from the wall through the hole of the mounting base and make the required connections using the “Four-wire installation” figure, and using the supplied solderless connectors. A pair of wires (black) must be connected to the power source (120-208-240 VAC) and another pair (yellow) must be connected to the heating cable. For connections with aluminum wires, you must use CO/ALR connectors. Please note that thermostat wires do not have polarity, meaning that any wire can be connected to the other.
• Page 6: Connect the wires of the floor temperature sensor at the indicated location behind the thermostat. Reinstall the front part of the thermostat on the mounting base and tighten the screw at the bottom of the unit. Turn on the power. Set the thermostat to the desired setting.
• Page 7: Operation Ambient temperature (Ambient mode) Floor temperature (Floor mode) Security mode Red indicator (EGFPD Test) First start-up: The thermostat is initially in manual modes. The temperature is displayed in degrees Celsius with a standard factory set point adjustment of 21°C. The hour displays --:-- and must be adjusted before switching to Auto or Pre Prog mode. The maximum floor temperature is limited to 28°C. Ambient and floor temperature: The figures displayed indicate the ambient temperature, ±1 degree, and the floor temperature, ±1 degree. Both temperatures can be displayed in degrees Celsius or Fahrenheit.
• Page 8: Temperature set points indicate the ambient or floor temperature settings. They can be displayed in degrees Celsius or Fahrenheit. To adjust the set point, press the + button to increase or the - button to decrease it by increments of 1 degree. To quickly scroll through set point values, press and hold the button. The maximum floor temperature is maintained at less than 28°C (82°F) to avoid overheating and potential damage or health issues. The adjustment procedure for the hour and the day of the week involves pressing the Day/Hr button in any mode. The day of the week can be adjusted using the + or - button, confirmed by pressing the Mode or Day/Hr button. The hour can be adjusted similarly, with confirmation required after setting. Minutes can also be adjusted using the + or - button, followed by confirmation. The adjustment process completes and the thermostat returns to the previous mode.
• Page 9: You can exit the adjustment mode of the day and hour by pressing the Exit button or by not pressing any button for 1 minute. In case of a power failure, the thermostat is self-sufficient for 2 hours. If the failure lasts less than 2 hours, the thermostat saves the adjustment of the hour and the day of the week. When the power is restored after an extensive failure, the hour and the day of the week are recovered, but you must update them. The thermostat can display the ambient temperature and the set point in degrees Celsius or Fahrenheit. To switch between degrees Celsius and Fahrenheit, simultaneously press down the + and - buttons for more than 3 seconds until the icon blinks. Press down the + button to switch between degrees Celsius and Fahrenheit. When the adjustment is completed, press down the Exit button or do not press any button for 5 seconds to exit the adjustment function. This adjustment can be done from any of the three principal modes. From the Manual mode, you can manually adjust the thermostat set point by pressing down the + or - buttons.
• Page 10: To quickly scroll through the set point values, press and hold down the button. From manual mode, the set points can range between 3 and 35°C and can only be adjusted by increments of 1°C. The thermostat will turn off if the set point is lowered below 3°C, and the set point value displayed will be --. The standard factory set point adjustment is 21°C in manual mode. You must adjust the hour before switching to other modes. To switch from manual mode to automatic mode, press down the Mode button. From the automatic mode, the thermostat adjusts the set points according to the programmed periods. If no data is entered, the thermostat acts as in manual mode with a standard set point of 21°C. It is possible to program 4 periods a day, meaning that the set point can change automatically up to 4 times a day. From this mode, the screen displays the temperature, the set point, the hour, the day of the week, and the current programmed period number.
• Page 11: Programming procedure of the automatic mode includes several steps for setting the desired schedule. To access the programming mode, press down the day of the week button you want to program. Select the period number (1 to 4) that you want to program using the + or - button. The hour can be adjusted from 00 to 23, and confirmation is required by pressing the Mode button. Minutes can only be adjusted by increments of 15 minutes. The period set point can be adjusted using the + or - button, with confirmation needed. After set point confirmation, the programming is completed, and the next period number blinks. You can continue programming by pressing the Mode button or select another period using the + or - button. At the end of period 4 programming, you automatically exit the programming mode. You can exit the programming mode at any time using one of three methods.
• Page 12: Press down the button of the day you are adjusting. Press down the button of another day to program it. Press down the Exit button. If you do not press down any button for more than 1 minute, the thermostat will exit the Programming mode. This mode enables the room to reach the selected temperature at the programmed hour by starting or stopping the heating before this time. The thermostat estimates the delay required to reach the set point of the next period at the programmed hour. The anticipated start icon will blink when the anticipated start of the next period begins. To activate or deactivate the anticipated start, the thermostat must be in Auto or Pre Prog mode. The anticipated start icon is displayed or hidden to indicate the activation or the deactivation of the mode. The anticipated start is initially activated when you enter the Automatic or Preprogrammed mode.
• Page 13: Deactivate the programming following the specified procedure if needed. You can apply the programming of one day of the week to other days by copying the programming day by day or in block. To copy the programming day by day, press down the source day button and hold it while pressing down the destination days one by one. If an error occurs when choosing a day, press down the erroneous day again to cancel the selection. After all selections are completed, release the source day button to apply the programming to the selected days. To copy the programming in block, press down the source day button and hold it while pressing down the last day of the block you want to copy. Hold down these two buttons for 3 seconds to activate the block copy. The block order is always increasing; for example, copying from Thursday to Monday will include Friday, Saturday, Sunday, and Monday. To erase a programming period, access the Programming mode and select the period to erase using the + or - button. You do not have to press down the Mode button to confirm the erasure.
• Page 14: The selection will not impact erasing. Simultaneously press down the + and – buttons to erase the period programming. The hour displays --:-- and the set point displays -- to indicate that the programming is erased. The erased period number blinks, allowing you to select another period to be erased or exit the Programming mode. The Preprogrammed mode allows an automatic programming of the thermostat. 252 preprogrammings have been defined for each mode. This mode enables quick programming using commonly used preprogrammings without manual input. It is possible to manually adjust the set point at any time from the Automatic mode. If the set point is lowered to off (--), the programming will not be effective. You can only access the Preprogramming mode when the thermostat is out of any programming or adjustment function.
• Page 15: Press down the Pre Prog button. The Pre Prog icon and saved selected preprogramming are displayed. This preprogramming can range between 0 and Z1. From the Pre Prog mode, you can choose the first 10 preprogrammings by pressing and releasing the Pre Prog button. To choose advanced preprogrammings, press down the Pre Prog button during 5 seconds. Once the letter is chosen, you must validate your choice by pressing down the Mode button. If you do not press down any button for more than one minute or press the Exit button, the thermostat exits the adjustment function and saves the current choice. The view of the selected preprogramming is made in a way similar to the Auto mode programming. It is impossible to modify the preprogramming. Press down the button corresponding to the day to view.
• Page 16: Choose the period number (1 to 2) to view using the + or - button. For each period, the hour and set point are displayed. You can also press down the Mode button to switch to period 2. At any time, you can exit the View mode using one of these 3 methods. If you do not press down any button during 1 minute, the thermostat quits the view mode. To switch from the mode to the mode, press down the A/F button. If the thermostat fails to detect the presence of a floor sensor, it will automatically revert to safe mode at a setpoint of 21°C. If you want to use the STCP thermostat with a temperature sensor already installed in the floor, you must contact customer service to validate compatibility. You must know the serial number and name of the installed sensor.
• Page 17: Temperature control is managed by the thermostat with high accuracy. A clicking sound is normal when the heating starts or stops, indicating the relay's operation. The screen backlights when a button is pressed and turns off after 15 seconds of inactivity. Pressing the + or – button once will activate the backlight without changing the set point value. The thermostat includes an Equipment Ground-fault Protection Device (EGFPD) that detects leakage currents of 15mA. If a defect is detected, the EGFPD activates, deactivating the screen and heating system. The EGFPD can be reinitialized by pressing the Test button or disconnecting the thermostat. Monthly verification of the EGFPD installation and operation is essential. The EGFPD verification procedure involves increasing the temperature set point and pressing the Test button. Successful tests will be indicated by the red light on the thermostat.
• Page 18: The display indicates the temperature. Press down the Test button to reinitialize the EGFPD, the red indicator turns off. The red indicator of the thermostat lights up and the display indicates E4. Disconnect the heating system at the electrical panel and call customer service. The thermostat has detected a ground-fault if the display shows only the time. Security mode imposes a maximum temperature set point that cannot be exceeded. It is possible to lower the set point while in Security mode. To activate Security mode, press down the + and - buttons for 10 seconds. The icon indicates that Security mode is activated after 10 seconds. To deactivate Security mode, cut off the power supply at the electrical panel and wait at least 30 seconds.
• Page 19: Restore the power supply to the thermostat. The icon will blink during a maximum of 5 minutes, indicating that you can deactivate the Security mode. Simultaneously press down the + and - buttons for more than 10 seconds. The icon will then be hidden indicating that the Security mode is deactivated. The thermostat saves some parameters in its nonvolatile memory to recover them when power is restored. These parameters include the current Man/Auto/Pre-Prog mode, the hour and the day of the week, and the last effective set point. The thermostat can detect a power failure and saves adjustments in volatile memory during this time. After a power failure, the thermostat enters a very low consumption mode and only displays the hour and day of the week. The thermostat is self-sufficient for 2 hours. If the power failure lasts less than 2 hours, the thermostat saves the adjustment of the hour. When power is restored after an extensive failure, it recovers the last mode and various adjustments that were effective when the failure occurred. During the first half hour of the failure, the hour and day of the week are displayed. After half an hour, the screen turns off to ensure energy saving.
• Page 20: Troubleshooting In normal operating conditions, the thermostat housing can reach nearly 40°C at maximum load. It is normal and will not affect the operation of the thermostat. Check if the thermostat is properly connected. Refer to the installation section. Heating does not run even if the thermostat indicates it is on. Check the power supply at the electrical panel. The display does not come on. Check the presence of an air stream or a heat source near the thermostat, and correct the situation. The display indicates E1, E2, or E3. Contact customer service for faulty thermal sensor issues. The display indicates E4. Check thermostat wirings for a bad contact. Weak luminosity of the display may indicate issues. If you do not solve the problem after checking these points, cut off the power supply at the main electrical panel and contact customer service.
