APPLICATION

Room temperature regulation for single-family or zoned heating installations by PI modulating control action of a valve operated by a reversible actuator.

The room temperature is monitored by an NTC 10 kΩ sensing element inside the controller.

Controls flow temperature in relation to shift in room temperature with a maximum limit of 45 °C.

Essential detectors for all models:

  • 1 plant flow detector.

Essential detectors for /D models:

  • 1 room detector.

FEATURES

  • Power supply: 230 V ~.

  • Consumption: 4 VA.

  • Protection: IP 20.

  • Voltage-free output contacts: rating 250 V ~, 5 (3) A.

  • Control of actuators with run times: 60 ... 120 seconds.

  • Setting range: 5...30 °C.

  • PI control action.

  • Proportional band: ± 1 °C.

  • Possibility of limiting setting range by means of pins supplied on request.
