COMPUTHERM E800RF Multizone Wi-Fi Thermostat Instruction Manual Overview

Summary of Contents

• Page 1: Multizone Wi-Fi thermostat With touch button controllers Operating instructions
• Page 2: A general description of the thermostat Important warnings and safety recommendations Meaning of the LED lights on receiver unit Information appearing on the display of the thermostat Functions accessible in the phone application Location of the thermostat and the receiver unit Connection and installation of the thermostat and the receiver unit Putting the thermostat into operation Setting up the internet control Basic operation of the thermostat
• Page 3: An example of dividing the heating system into zones is shown in the figure below. By dividing a heating/cooling system into zones, the various zones can operate either simultaneously or independently of each other. This way only those rooms are heated at a given time, whose heating is required. More than 8 zones can be controlled by using additional COMPUTHERM E800RF (TX) thermostats. In this case, the potential-free boiler output (NO-COM) must be connected in parallel to the boiler. The zone outputs work independently. There is a wireless (radio frequency) connection between the thermostats and the receiver units.
• Page 4: The thermostat and receiver have their own security code for safe operation. Installation, connection, and synchronization of the receiver with the thermostats are detailed in Chapter 7. The thermostat repeats its current switching command every 6 minutes. Heating/cooling control is maintained after a power failure if selected in the settings (see Chapter 11). The transmitter range in open field is approximately 250 m, reduced indoors by obstacles. Portability of the thermostat allows for no cable installation, beneficial for modernizing old buildings. Optimal device location can be selected during operation, allowing movement between rooms. Thermostats connected to the multi-zone receiver can be controlled via the Internet and touch button interface. Automatic control based on temperature and time is available for the device. COMPUTHERM E800RF thermostats can control gas boilers, heating/cooling systems, electric water heaters, solar systems, and other electric devices.
• Page 5: Functions accessible in the phone application.
• Page 6: Location of the thermostat and the receiver unit It is expedient to install the thermostat in a room used regularly or for a prolonged stay. The optimal position for the thermostat is at a height of 0.75-1.5 m from the floor level. The receiver of the COMPUTHERM E800RF thermostat should be installed near the boiler. The receiver should be protected from moisture, dust, chemicals, and heat. Install the receiver at a distance of at least 1-2 m from the boiler and other large metal structures. The recommended height for the receiver installation is 1.5-2 m. Check the reliability of the radio frequency connection at the selected location before installing the receiver. Do not install the receiver under the boiler cover or near hot pipes. If radiator valves are equipped with a thermostat head, set it to maximum level or replace it with a manual regulating knob.
• Page 7: Connection and installation of the thermostats and the receiver unit. Make sure that the Computherm E800RF thermostat and the apparatus to be controlled are de-energized while putting them into operation. The device should be installed and put into operation by a competent person. If you do not possess the necessary skills and qualifications, please get in touch with an authorized service. The modification of the device poses a risk of electric shock or breakdown. We recommend that you install the heating system in such a way that the heating liquid can circulate in the closed position of all zone valves. This can be achieved with a permanently open heating circuit or by installing a by-pass valve. Connect the front of the thermostat to its holder, then connect the USB-C power cable to the back of the holder. Connect the other end of the USB cable to the adapter included in the package and connect it to the 230 V mains.
• Page 8: Putting the receiver unit into operation involves loosening the screws on the bottom without removing them completely and separating the front panel from the back panel. Fasten the back plate with the supplied screws to the wall near the boiler. Connection points on the electrical panel are marked as L, N, 1, 2, 3, 4, 5, 6, 7, 8, NO, COM, and NC. The receiver controls the boiler or air conditioner via a potential-free relay with connection points NO, COM, and NC. Connect the room thermostat to the NO and COM terminals in the rest open state. If the controlled device lacks a thermostat connection point, disconnect its power supply wire and connect it to the NO and COM points of the thermostat. Always consider the load capacity of the receiver and follow the manufacturer's instructions for the controlled device. The receiver can control multiple heating/cooling zones and a pump. Zone valves must be connected to points 1 through 8 of the terminal block. A voltage of 230 V AC appears at the connection points of the pump in response to the heating/cooling command from any thermostat.
• Page 9: The back of the receiver contains important connection details for the heating unit. The receiver unit is designed for 230 V AC and 50 Hz power supply. Zone valves can be connected to the receiver, accommodating up to 2-3 parallel devices. If more devices are needed, such as 4 zone valves, they should be combined before connecting to the zone controller. For slow-acting electrothermal zone valves, it is advisable to delay the boiler start if all valves are closed to protect the boiler pump. The 230 V power supply must be connected to the terminals marked N-L inside the receiver unit. This power connection does not appear on the output connection points of the boiler control relay. The neutral wire should connect to the N point, and the phase wire to the L point. Proper wiring is essential for the safe operation of the heating system. Refer to Chapter 11.7 for more information about output delay settings.
• Page 10: Pay attention to the phase correctness when connecting the power supply. It is not necessary to connect a ground because the product is double insulated. The grounding point on the electrical panel is only an option for grounding the product connected to the receiver. The thermostat and receiver unit are synchronized in the factory. They have their own security code for safe operation. If they do not communicate, follow the steps to synchronize them. Look at the 14-digit identification code inside the receiver. Enable the “synchronize with receiver” function in the thermostat. Turn off the thermostat, then touch and hold the arrow while tapping the button. A sign will appear on the display with a two-digit number that must match the first two digits of the identification code on the receiver unit. If the displayed number does not match, use the arrows to change it. Press the button on the thermostat to set the next digits in a similar way. After setting the appropriate value, touch the menu button to complete the synchronization process.
• Page 11: The left side contains a verification code. If this number does not match with the last two digits of the number sequence on the receiver unit, one of the SN values has been set incorrectly. Start the alignment again and check the set values. If the value displayed on the thermostat matches the last two digits of the number on the receiver, press the button again. The thermostat’s display shows the text on the right and the number on the left. This function may be used in a future development of the product. Do not change this value, just tap to complete the synchronization. The thermostat synchronizes with the receiver within 1 minute after performing the synchronization steps. After a short time when finishing synchronization, the “Synchronize with receiver” function is automatically disabled and remains disabled until it is re-enabled. The thermostat repeats the on/off commands to the receiver unit every 6 minutes.
• Page 12: Setting up the internet control involves installing the application. The thermostat can be controlled by both a smartphone and a tablet with the help of a free application. The application is available for iOS and Android operating systems. The applications can be accessed through a specific link or using a QR code. The application is available in English, Hungarian, and Romanian languages. It automatically displays in the language corresponding to the default settings of the phone. If the default settings are not one of these three languages, it is displayed in English.
• Page 13: Connecting the thermostat to a Wi-Fi network is necessary for remote control. The COMPUTHERM E800RF can operate on a pre-set program without a permanent Internet connection. The thermostat only connects to a 2.4 GHz Wi-Fi network. To synchronize, switch on the Wi-Fi connection on your phone or tablet and join the 2.4 GHz Wi-Fi network. Activate the GPS location feature on your phone. Start the COMPUTHERM E Series application and grant all requested access. Touch and hold the button on the thermostat for approximately 10 seconds until the symbol on the display flashes quickly. In the application, touch the Configure icon. Ensure your phone is connected to the desired Wi-Fi network and enter the network password. The connection is successful when the symbol on the thermostat's display illuminates continuously.

Tapping the button you can switch between the functions to be set. A given function can be set by arrows. To exit the settings menu and save the settings: Switch the appliance off and on again using the button, or Wait 15 seconds until the thermostat display returns to the main screen, or Scroll through the settings by pressing the button.
• Page 19: The setting options are shown in the table below. Selecting switching sensitivity (DIF) allows you to specify how much the appliance switches the connected device on/off below/above the set temperature. The lower the switching sensitivity value, the more uniform the internal temperature of the room. The switching sensitivity does not affect the heat loss of the room. Defining maximum and minimum settable temperatures is possible. Calibration of the temperature sensor can be performed. Antifreezing settings are available. Memorizing ON/OFF status in case of a power failure is an option. Changing between heating or cooling mode is supported. Resetting to factory default settings can be done.
• Page 20: In case of higher comfort requirements, the switching sensitivity should be chosen to ensure the most constant internal temperature. The switching sensitivity can be set between ±0.1 °C and ±1.0 °C. We recommend setting ±0.1 °C or ±0.2 °C as the factory default setting. The measuring accuracy of the thermometer of the thermostat is ±0.5 °C. The temperature displayed by the thermostat can be modified in 0.1 °C increments, but the modification cannot exceed ±3 °C. When the antifreezing function is activated, the thermostat will switch on its output when the temperature goes below 5 °C. When the temperature reaches 7 °C, normal operation of the output is restored. The Memorizing Settings function allows the thermostat to continue operating after a power failure. The thermostat can be set to turn off and remain off until altered, or return to the same state it was in before the power failure. The default setting for the power failure mode is to return to the previous state.
• Page 21: Output delay function does not work for the switch-on signal of additional thermostats. To activate/deactivate the output delay function, press the delay button inside the receiver for approx. 3 seconds. For safety reasons, use a non-conductive device to press the button. The activated status of the output delay function is indicated by the continuously lit purple LED labeled delay inside the receiver. The thermostat has the following 2 positions: off position and on position. You can switch between off and on positions using the phone application or by tapping the button on the thermostat. When the thermostat is off, the screen of the devices turns off and the relay outputs of the device go into off (open) position. When the thermostat is on, the display of the device illuminates continuously. When the thermostat is on, it possesses the following 2 modes of operation: manual mode and programmed auto mode.
• Page 22: You can switch between the modes using the phone application or on the thermostat. The currently selected mode is indicated in the phone application and on the thermostat. The two modes are described in detail in the following sub-chapters. In manual mode, the thermostat maintains a preset temperature until the next intervention. The temperature to be maintained by the thermostat can be specified in 0.5 °C steps. The currently set temperature can be modified using the phone application or on the thermostat. Programming means setting of switching times and selection of corresponding temperature values. Any temperature set for a switch will remain in effect until the time of the next switch. Switching times can be specified with an accuracy of 1 minute. The temperature range has minimum and maximum values.
• Page 23: The device can be programmed for a period of one week. In the programmed auto mode, the thermostat operates automatically and cyclically repeats the entered switches every 7 days. 5+2 mode allows setting 6 switches per day for 5 working days and 2 switches per day for 2 days of the weekend. 6+1 mode allows setting 6 switches per day from Monday till Saturday and 2 switches on Sunday. 7+0 mode allows setting 6 switches per day for every day of the week. Unnecessary switches can be eliminated by setting their time and temperature to the last switch you want to use. To enter programming mode, touch the display icon. The indication of the currently selected programming mode is located at the top of the screen for programming. You can switch between programming modes by touching the programming mode indication. You can modify data (time, temperature) of switches by tapping the value concerned.
