The DRX2 controls floor heating/cooling valves via triac or analog outputs, regardless of available I/Os. 3-position actuators, thermal pulse width modulation (PWM) actuators, PWM actuators with return spring can be connected to the triac outputs.
A maximum of 1 thermal valve can be connected to each triac on the DXR2 with AC 230 V power.
Conventional 0…10V actuators as well as 6-port valves can be connected to analog outputs.
