Attach the electrical cables using the cable pass-through
located in the electrical box in order to ensure good resistance
to pulling (for the 14kW model, use the anti-wrench connector
supplied with the appliance).
13.4 Hot domestic water controller function and
components description

DHW controller function description :
A- Limit the time duration in dhw mode in order to not bloked
heating mode and to optimzed the tank Heat pump temperature
set point.
B- Alternative operation between HP end immersion heating.

Apply power to timer. Output contacts transfer immediately and
cycle between ON and OFF for as long as power is applied. The
ratio is 1:1 (time on = time off).
Temporization setting requirements:
-
For low thermal inertia installation (radiators) the time T1 must
be set to 30 minutes.
-
For High thermal inertia installation the time (floor heating) T1
must be set to 60 minutes.
i
Note : The HP will run T1 minutes alone then the
electrical back up will run to complete the DHW
demand if the HP has not achieved it alone. Important
T1 value could maximize the HP usage in DHW mode
but will be not available for heating mode during
T1 value (Risk of comfort or Heating electrical back
up usage according installation thermal inertia
characteristics)
