TTC 3-phase controller for electric heating

TTC is a 3-phase triac controller for control of electric heaters. The device is connected in series between the power supply and an electric heater or radiator. TTC has a temperature controller with inputs for sensors placed, for instance, in a supply air duct or room.
It can also be controlled using an external control signal. The controller utilises stepless, time-proportional control.
Triac control is considerably more accurate than on/off control, meaning increased heating comfort and lowered energy costs.
TTC controller is available in several types: for DIN-rail mounting and for wall mounting.


TTC has a built-in function for automatically adaptating the control mode as needed:

  • supply air control
  • room temperature control
  • control of larger loads
