Input2 - Selfio FlowBox-HC Guide D'installation Et D'utilisation

Inst:  System parameters: Input, "C_b"
In case of mutizone regulation "WFHC Master RF with or without Heat&Cool function" is installed you
could use the input 1 to connect the pump relay output to swtich off the circulation pump1 in case of no
water circulation demand is asked in the house.
Note:
- The heating output will follow the circulation demand from the pump1.

Input2

Inst:  System parameters: Input, "HC"
You could use the input 2 to connect the an external signal which give the Heating or Coling working mode
of the installation (This signal could be done directly by a reversible input).
"HC" is only available if Input1 is set on "no or Aqua"
Inst:  System parameters: Input, "Aqu"
You could use the input 2 to connect the an immersion thermostat witch schould be placed in a storage
tank. In Heating mode this immersion thermostat will be use to switch off the circulation pump to avoid cold
water circulation in the circuit if the storage tank is discharged.
The immersion thermostat connected on the Input2 will manage the working of the main circula-
tion pump (Mixed circuit) if the ClimaticControl-HC drive only one pump.
In the installation with two circulations pumps, the immersion thermostat connected on the Input2
will manage the working of the 2
Note:
- The heating output will stay activated even if the aquastat have stopped the circulation pump.
- To avoid problem in cooling mode, if the storage tank is filled with cold water (by heat pump...) the
aquastat function will be automatically desactivated.

The WFHC connecting box connected on the Input2 will manage the working of the main circula-

will manage the working of the 2
Example 1: Reversible installation with circulation pump (UFH application).
In1 Used to change the working mode of the installation, signal from Heat Pump (Inst:  System parameters: Input, "HC")
In2 used to stop the pump when D.H.W is in demand (Inst:  System parameters: Input, "Aqu")
Attention:
In case of the CLIMATICCONTROL-HC must be linked with the Heat pump (from the Heat /
Cool switch)
Pay attention to check the compatibility of the electrical signal before connection.
The inputs 1 or 2 (Inst: Parameter menu: In1, In2 "HC") need a live signal "Phase L" to works
in cooling mode.
