Hello,

I need to setup the ATR121 controller to control the temperature inside winterization package, it should turn the heaters ON when temperatures drop below -5C and turn them OFF when it's reached +10C. By my understanding we need to setup: Regulation type(rEG.) - "HEA", Command hysteresis(HY.c) - "15", and the main setpoint value to -5C. Is the correct parameters for this case?

Thanks!

Hi,
you must insert 10°C as setpoint (temperature when output is switched off) and [Hy.c] to "15" (so it power-on the relay if temperature goes below -5°C (Setpoint - hysteresis).
