• For the “2-pipe” TWN C electric heating or 2 and “4-pipe”.
• Control by actuating the 230 V "on/off" valves and/or the ventilation control.
• For all technical information concerning the operation of these controls, consult the corresponding Technical Instructions.
F - Sensors accessories
Important:
- The sensor inputs (B1-M and B2-M) of "RCC" controls being connected to the 230 v, use cable which
satisfies the corresponding insulation requirements.
- Maximum connection length: 10 m with 1.5 mm
2
.
- To avoid electromagnetic disturbance, do not route sensor connection next to power cables.
• Temperature sensor (bare) for RCC remote controls - code 70250053
- Type CTN 3 kΩ at 25°C.
- IP 65 - cl. II.
- 2 uses possible:
- Change-over sensor (heating / cooling switch) for TWN 2-pipe heating and cooling:
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 insulation assembly (not supplied) to ensure that the true temperature
is recorded.
- Air temperature sensor:
The RCC type 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 diagrams above.
