TT2 Thermostat controller

The TT2 Thermostat controller is equipped with two high-current relays to which an electric immersion heater of up to 3.6 kW (230 V~) / 1.8 kW (115 V~) can be connected. Thus, the TT2 manages the time and temperature control of the electric backup heating for a DHW store. The rapid heat-up function makes for extra comfort. A wireline remote control with an integrated LED enables a comfortable operation of the rapid heat-up function.
