Heatit Triac thermostat

The Heatit Triac is an electronic thermostat that can be set to function in two different ways: As an effect regulator, or controlled by an external sensor. The thermostat has a switchback temperature option.

In effect regulator mode the thermostat regulates the temperature by switching on and switching off in intervals. Switch-
on and switch-off is done via triac. This eliminates electronic noise and clicking. In external sensor mode, the effect is regulated by temperature.

The Heatit Triac uses time proportional control with a cycle of about 42 seconds. This means that the heating element is switched on and off in a pulse/pause interval. The average power is set to the desired temperature. The pulse/pause interval is controlled by a triac.

The thermostat is designed for electrical heating.

The desired pause/pulse interval can be set steplessly from 0 to 10.
For example, if the thermostat is set to 5, the heating element will be switched on for 21 seconds and switched off for 21 seconds.

effect regulation principle

The thermostat is set to 22°C

  • If the floor temperature is 21°C or lower, the heat is on constantly.
  • If the floor temperature is 21,5°C ,the heat is set to 75% effect.
  • If the floor temperature is 22°C ,the heat is set to 50% effect.
  • If the floor temperature is 22,5°C ,the heat is set to 25% effect.
  • If the floor temperature is 23°C or higher, the heat is switched off.

The hysteresis is + -1°C from set temperature.
