Hot water coil intergrated (H) / Changeover water coil (CO) et cold coil C
For units equipped with a cold battery or changeover, the additional module is equipped with a removable stainless
steel condensate tray with integrated siphon. Connection of the PVC pipe diameter 32 to predict.
Connection between the additional module and the B1 junction box to be made.
Pay attention to let the doors free of access (ducts, cables)
In the ELITE and EDEN version, the battery is already installed in the central unit, the Antifreeze Thermostat is connected.
However, you must wire the 3-way valve. If you are using a hot coil battery, also connect the THA (Thermostat Antifreeze)
and remove the supply temperature sensor after the battery
THE VALVE MUST BE CONNECTED OFF
Connect the actuator of the 3-way valve as follows:
