COMPUTHERM E800RF

Multi-zone Wi-Fi thermostat with wireless touch button controllers

The basic package of the device includes two wireless programmable Wi-Fi thermostats and a receiver. If required, it can be expanded with 6 more COMPUTHERM E800RF (TX) Wi-Fi thermostats. The receiver receives the switching signals of the thermostats, controls the boiler and gives commands to open/close the heating zone valves (max. 8 zones) belonging to the thermostats, as well as to start the pump connected to the common pump output. The zones can be operated separately or even simultaneously. This way only those rooms are heated at a given time, whose heating is required. With internet access, devices connected to the thermostat can be remotely controlled and their operation can be checked using your mobile phone or tablet. The thermostats enable you setting the switching sensitivity, calibrating the heat sensor, easy switching between cooling and heating modes and locking the control buttons. We recommend it for places where programmability and the division of the heating system into zones are needed, and remote control, accurate temperature measurement and temperature setting, portability and switching accuracy are also important.
