4.6 Heating and cooling outputs
There are 2 Free contact Outputs (Fig. A):
• Heating output.
• Cooling output.
You can configure 2 types of Output using DIP switch 6:
• Demand: Heating or cooling outputs will be triggered if there is any heating or cooling
demand in the installation.
The output follows the pump output on the main controller (See 4.5).
DIP switch 6= OFF
• Mode: Heating or cooling outputs follow the working mode of the installation.
DIP switch 6= ON
See 3.3
The switching between Heat or Cool mode is detected in a few seconds.
If DIP switch 5= ON, when the H&C mode is switched over, we stop immediately the current
mode output, we wait at least
• 5 min in mode configuration (DIP switch 6= ON)
• 5min plus the demand in demand configuration (DIP switch 6= OFF)
with no active outputs then we activate the reverse mode output. During the transition period
with no active output, the system is considered to be in the reverse mode (H&C led).
See 3.3
2 Live, Neutral connectors allow to convert the outputs in live contact (See Fig B).

4.7 Humidity detection input, dehumidifier output
The product has a humidity detection input.
Format of the signal:
The input is a free contact
When humidity is detected in cooling mode:
• the local pump is stopped
• the local actuators are closed
• the local cooling is stopped
• the local dehumidifier is started
• the drier led becomes fix green (See 3.1).
As long as the signal remains closed, this behaviour is maintained.
Remarks:
• Humidity detection must be connected on a controller with a pump to be able to stop it.
• When the controller cooling output manages the cooling of the whole installation, the cooling is stopped for the whole
installation when humidity is triggered.
