    8.12 Dual action heating-cooling ATR142 is suitable also for systems requiring a combined heating-cooling action. Main command output must be configured foe hearting PID ( act.t. = Heat and p.b. must be greater than 0), and one of the alarms ( AL. 1 or AL. 2 ) must be configured as cooL. Command output must be connected to the actuator responsible for heat, while the alarm output will control cooling action.
