2/ Heat & Cool detection by contact: (“HC” = CtAC)
Open => The system will work in heat mode
Closed => The system will work in Cooling mode
Check the heat pump output before connection.
1/ Heat & Cool detection by sensor: (“HC” = SenS)
The heat & Cool input is used with a sensor to detect
the water temperature in the incoming pipe of the
installation, to decide the working mode. (Must be
mounted on the incoming water pipe of the manifold
with precautions).

1/ Humidity detection by NTC sensor:
The NTC sensor is used to control the water
temperature in the pipe. If the temperature in the pipe
is too cold the cooling output will be deactivated to
avoid risk of humidity in the house. (Must be mounted
on the incoming water pipe of the manifold with
precautions).
2/ Humidity detection by contact sensor
(free contact)
The humidity sensor is used to control the water
temperature in the pipe. If condensing has detected on the
pipe the cooling output will be deactivated to avoid risk of
humidity in the house.
Open => The installation works in normal way.
Closed => The humidity function will be activated.
