• Control by action on the 30V "On/Off" valve.
• Permanent or slaved ventilation.
• Mode change possible (Eco or Stand-by) by external contact.
• For all technical information concerning the operation of this controller, consult Technical Instructions No. 10 1 151.

(if used)
D - temperature sensor accessories
Important:
- the sensor inputs (B1-M and B2-M) of the remote controls being connected to the 230v, use cable which
satisfies the corresponding insulation requirements.
- Maximum connection length: 10 m with 1.5 mm
- to avoid electromagnetic disturbance, do not route sensor connection next to power cables.
• temperature sensor (bare) for the remote controls "rcc" - code 70250053
- Type CTN 3 kΩ at 5°C.
- IP 65 - cl. II.
-  uses possible:
- change-over sensor heating/cooling switch) for -pipe heating and cooling models:
Use a retaining clip to secure this sensor to part of the piping representative of the water temperature in the
system.
Use thermoconductive paste and cover the sensor with insulation (not supplied) to ensure that the true
temperature is recorded.
- air temperature sensor:
The thermostats operate according to the ambient air temperature measured internally or according to the
temperature indicated by the external sensor (switching takes place automatically as soon as the external
sensor is connected).
Control connection as per the following diagrams.
Important: If an air recirculation sensor is installed in the unit, the fan must operate on a permanent
basis (mandatory valve).
• air temperature sensor in box for the remote controls "rcc" - code 70250054
- Type CTN 3 kΩ at 5°C.
- IP 30 - cl. II.
- air temperature sensor:
The thermostats operate according to the ambient air temperature measured internally or according to the
temperature indicated by the external sensor (switching takes place automatically as soon as the external
sensor is connected).
Control connection as per the following diagrams.
