ME210 Triac power amplifier

Triac power amplifier

To connect up to 4 thermic actuators to UC..., FC... controllers and UI.... room units. Contains a 24 V / 2 A triac. Flush box installation (under the room unit), dimensions 49 x 49 x 14 mm.

Datasheet

ME220 is a triac module controlled by a 24 V AC signal. It amplifies the 24 V AC PWM output signal from an IRC controller or room unit (UI..., UX..., UC..., FC..., US...), which are able to control maximum 2 actuators per output only.

  • Control of more radiators, fan coils, or any other heating or cooling circuits by a single controller.

In a plastic casing suitable for monting into a flush box there is a board with terminals, triac and other components. When the input is energized the triac opens and gives 24 V AC control voltage for the actuators at the output terminals. 

If more radiators or cooling panels are situated in a single space and controlled together, some of them may be hot while others stay cold. This is due to the characteristics of the actuator and valve set together with the hydraulic parameters of the installation, and it does not indicate wrong function of the controller or of the triac amplifier.
