Computherm T70RF Wireless Digital Programmable Room Thermostat

The COMPUTHERM T70RF type switched-mode room thermostat is suitable to regulate the overwhelming majority of boilers and air conditioners available. It can be easily connected to any gas boiler having a two-wire thermostat connection point and to any air conditioning apparatus or electrical apparatus, regardless of whether they have a 24 V or 230 V control circuit.

Easy to program wireless room thermostat. With its large digital display and touch buttons, you can set an hourly program for each day of the week. It provides more accurate temperature measurement and temperature adjustment than mechanical thermostats, as well as the ability to switch between heating and cooling modes, calibrate your temperature sensor and lock the control buttons. Can be set a comfort, a saving and an absence temperature.

The simultaneous use of several COMPUTHERM room thermostats and one COMPUTHERM Q4Z zone controller provides the possibility for the thermostats to also control a pump or a zone valve in addition to starting the heater. This way it is easy to divide a heating system into zones, thanks to which the heating of each room can be controlled separately, thus greatly increasing comfort. Furthermore, the zoning of the heating system will greatly contribute to the reduction of energy costs, as due to this only those rooms will be heated at any time where it is required.

The device consists of two units. One of them is the portable control unit (thermostat), while the other unit is the receiver that controls the boiler. Because there is a wireless (radio-frequency) connection between the two units, no cable is required between the thermostat and the boiler.

Temperature can be measured and set at digital display more precisely as compared to simple, conventional thermostats. We recommend using it in places where programmability is not required, but accurate temperature measurement, accurate temperature setting and switching sensitivity is important.
