ATR 244-12ABC parameters list: ATR 144-ABC parameters list: Description of the application:
Hot setpoint set to 20 degrees: the controller heats up (active Q1) to 20°C (restart at 18°C).
Cold setpoint (intervention AL) set to 25 degrees: the controller cools down (active Q2) if the temperature exceeds 27°C (switch off at 25°C).

Cold setpoint (intervention AL) set to 2 degrees: the controller cools down (active Q2) if the temperature is 2°C higher than the hot setpoint.

Please note Once all setpoints have been set, you can enter the parameter configuration again and hide the cold setpoint using parameters:
25[P.SE.] = "Pr.A." for ATR121/141
30[A.1.S.P.]="HidE" for ATR142/ATR243-20ABC.
P_135[A.I.S.P.]="Hide" for ATR244-12ABC
P_71[A.I.S.P.]="Hide" for ATR144-ABC
In this way the user will always set the heat reference setpoint.
