Functions The controller acquires the room temperature with its integrated sensor and maintains the setpoint by delivering control commands. It is possible to choose PI control with PWM actuating commands or two-position control with ON / OFF actuating commands. The proportional band or the switching differential can be 1 or 4 K in heating mode and 0.5 or 2 K in cooling mode (selectable). The integration time cannot be adjusted and is 10 minutes.

Note Output Y1 (heating): when used in connection with thermic actuators, the selected interval should be 240 seconds. When using electric heaters, it should be 90 seconds. Caution When used in connection with electric valve actuators, DIP switches no. 5 and no. 6 must be set to ON for two-position control.
