C - Connections with automatic remote control RCC 10 - code K 60 D 051 Z
• Automatic switching of the operating mode, by sensor or external contact.
Note: If the control is to operate only in cooling mode, shunt terminals M and B2 (otherwise the unit will remain in
heating mode).
• Control by action on the 230V "On/Off" valve and/or on ventilation.
• 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 12 151 .

E - Temperature sensor accessories
Important:
- The sensor inputs (B1-M and B2-M) of RCC control 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 RCC remote controls - code K 60 D 053 Z
- Type CTN 3 kΩ at 25°C.
- IP 65 - cl. II.
- Use:
- Change-over sensor heating/cooling switch) for MSW3 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 in box for RCC remote controls - code K 60 D 054 Z
- Type CTN 3 kΩ at 25°C
- IP 30 - cl. II.
- 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.
