In Manual mode, the thermostat displays the current room temperature and the word MAN. In OFF mode, it displays the current room temperature and the word OFF. In AUTO mode, it shows the current room temperature, the number of the current program, and the word AUTO.
• Page 17: Setting the date, time and programming mode involves pressing specific buttons to adjust the year, month, day, hour, and minute. You can switch between 5/2d and 7d or 24h mode. Daylight saving time can be turned on or off. The thermostat will return to normal operation after 20 seconds or by pressing a button. Holiday mode switches the thermostat off while enabling frost protection. You can set the start and end time for holiday mode. The thermostat will remain off during the holiday period. The holiday function can be canceled by pressing a button for 5 seconds.
• Page 18: How your programmable thermostat works When the thermostat is in the AUTO mode, it will operate according to the times and temperatures that have been programmed. The user can select from 6 different programs per day, each with a time and a temperature. There is no OFF time, only a higher and a lower target temperature. If the user wants the thermostat to be OFF at a certain time, set the temperature for this time to be low. The thermostat will turn ON if the room temperature is lower than the target temperature for the current period. Example: If P1 is set to be 21˚C at 6am, and if P2 is set to be 10˚C at 8am, the thermostat will look for the temperature to be 21˚C between 6am and 8am.
• Page 19: Factory program setting includes various time and temperature settings for different days. The schedule is divided into three programs: P1, P2, and P3. Each program has specific temperature settings at designated times throughout the day. Typical settings include 21˚C in the morning and evening, with lower temperatures during the day. The program is designed for both weekdays and weekends, with specific settings for each. The 24-hour program allows for continuous operation with specified temperature adjustments. Temperature settings vary from 10˚C to 21˚C depending on the time of day. The document outlines settings for Monday to Friday and Saturday to Sunday. The controls are provided by EPH Controls Ltd. The manual appears to be focused on user-defined temperature scheduling.
• Page 20: Programming modes of the RDTP Room Thermostat include 5/2 Day mode, 7 Day mode, and 24 Hour mode. 5/2 Day mode allows programming Monday to Friday as one block and Saturday and Sunday as a second block, with each block having 6 different times and target temperatures. 7 Day mode enables programming all 7 days individually with different times and target temperatures. 24 Hour mode allows programming all 7 days as one block with the same times and target temperatures. In 7 Day mode, each day can be programmed with 6 individual times and temperatures. In 24 Hour mode, each day can only be programmed with the same 6 times and temperatures.
• Page 21: Adjust the program setting in 5/2 day mode. Programming for Monday to Friday is now selected. Adjust the P1 time and temperature. Repeat this process to adjust P2 to P6 times and temperatures. Programming for Saturday to Sunday is now selected. Adjust the P1 time and temperature. Repeat this process to adjust P2 to P6 times and temperatures. Press to return to automatic mode. While in programming mode, pressing will jump to the next day.
• Page 22: Temporary override allows adjustment of the target temperature in AUTO mode. Press buttons to adjust the target temperature. The thermostat will operate to the new target temperature until the next switching time. Permanent override can be activated by selecting manual mode. Adjust the target temperature in manual mode. The thermostat will operate to the new target temperature. To cancel permanent override, press until AUTO or OFF mode is selected.
• Page 23: Boost function allows the thermostat to be set to a specific temperature for 1, 2, or 3 hours. This feature is available in all modes except for holiday mode. Pressing 1, 2, or 3 times will display the end time of the boost program on the screen. Adjust the target temperature by pressing the appropriate buttons. Press or wait for 5 seconds to activate the boost. The screen will display 'BOOST TO' along with the end time for the boost program. Press again to deactivate the boost. The thermostat will revert to its previous operating mode after deactivation.
• Page 24: Menu function allows the user to adjust additional functions. To access the menu, press and hold specific buttons together for 5 seconds. P01 operating mode has three settings: Normal, Delay Start, or TPI mode. The default setting is Normal. Press and hold specific buttons together for 5 seconds to access the mode selection. ‘P01’ will appear on the screen for mode selection. Use the designated buttons to select between Normal mode, Optimum start mode, or Time proportional integral mode. Press the designated button to confirm the selected mode.
• Page 25: Normal mode activates when the temperature falls below the target temperature. The thermostat will demand heat in this case. When the temperature rises above the target temperature, the demand for heat is canceled. The graph illustrates the normal mode with on/off control. The target temperature is set at 21˚C. The temperature readings range from 17˚C to 22˚C. Time is measured in minutes, ranging from 0 to 100.
• Page 26: Optimum Start Control (OS) allows the thermostat to reach the target temperature by the start of the next switching time. The thermostat sets a time interval (Ti) to 10, 15, 20, 25, or 30 minutes to increase the room temperature by 1°C. To achieve the target temperature when the program starts, the thermostat reads the room temperature (RT), setpoint temperature (ST), and target temperature difference (TTD). TTD is the difference between the setpoint temperature and the room temperature. The time to overcome TTD is called Optimum Start Time (OST), with a maximum value of 3 hours (180 minutes). OST is subtracted from the start time. As the temperature increases, the thermostat recalculates the OST.
• Page 27: Optimum start control graph with Ti = 20. Optimum start control graph with Ti = 15. Optimum start control graph with Ti = 10. Example when Ti = 20: The thermostat will start the heating at 05:30am to reach 21°C for 06:30am. Example when Ti = 10: The thermostat will start the heating at 06:00am to reach 21°C for 06:30am. Target temperature difference ˚C. Program 1 on the thermostat is 21°C for 06:30am and the room temperature is 18°C. Target temperature difference ˚C. EPH Controls Ltd.
• Page 28: Operating mode Time proportional integral mode (TPI) affects the thermostat's operation when the temperature is rising and falls into the proportional bandwidth section. The thermostat will turn on and off to prevent overshooting the target temperature. It will also activate if the temperature is falling to avoid undershooting the target. This results in a more comfortable level of heat for the user. Two settings affect the thermostat's operation: the number of heating cycles per hour and the proportional bandwidth. The number of heating cycles per hour determines how often the thermostat cycles the heating on and off. You can select from 2, 3, 6, or 12 cycles per hour.
• Page 29: Proportional bandwidth refers to the temperature below the target at which the thermostat will start to operate in TPI control. You can set this temperature from 1.5°C to 3.0°C in 0.1°C increments.
• Page 30: Operating mode Time proportional integral mode (TPI) Once TPI mode is selected, ‘CYC’ and ‘06’ will appear on the screen. Use and to select from 2, 3, 6 or 12. Press to confirm. ‘P Band’ and ‘2.0’ will appear on the screen. Use and to select from 1.5 to 3.0. Press to confirm. Press to return to normal operation.
