Hydraulic unit
Access to connection terminals :
- Remove the front plate.
- Open the power control box.
- Make the connections according to the diagram
(
fi g. 44, page 39).
Do not place the sensor and power supply lines
parallel to each other to avoid interference due
to voltage spikes in the power supply.
Make sure that all electrical cables are housed
in the areas provided for this purpose.
▼
Interconnection between outdoor unit
and hydraulic unit
Match up the terminal block markers on the hydraulic
unit to those of the outdoor unit exactly when connecting
the interconnection cables.
An incorrect connection could result in the destruction
of one or other of the units.
▼
Electrical backup
If the heat pump is not installed with a boiler connection:
- Connect the power supply for the backup to the
electrical panel.
▼
Boiler connection (option)
If the boiler connection option is used,
the electric backup must not be connected.
- Please refer to the instructions supplied with the boiler
connection kit.
- Please refer to the instructions supplied with the boiler.
▼
Second heating circuit (option)
- Refer to the instructions supplied with the second
hydraulic circuit kit.
▼
Contract with Energy Supplier
The heat pump can be set to operate within particular
types of energy contract, e.g. off -peak, PV (Photovoltaic).
In particular, domestic hot water (DHW) at the comfort
temperature will be produced at off -peak times when
electricity is at its cheapest.
- Connect the "Power Provider" contact to input EX2
(fi g. 45, page 39).
- Set the DHW confi guration to "Off -Peak".
• 230V on input EX2 = "Peak Hours” information activated.
(Base setting / Line modifi cation possible 5983,
Confi guration menu).
▼
Power limitation or EDR (Energy Demand
Reduction)
Power limitation is designed to reduce electricity
consumption when it is too high for the contract signed
with the energy supplier.
- Connect the power limiter device to input EX1 (
fi g. 45,
page 39
). Heat pump and DHW backups will be shut
off in the event of over-consumption by the dwelling.
• 230 V on input EX1 = power limitation in progress
(Base setting / Line modifi cation possible 5981,
Confi guration menu) (Operating line 2920).
During the power limitation or EDR, the
outdoor unit errors are not displayed on the
hydraulic unit.
▼
Faults external to the heat pump
Any component which reports back information
(Underfl oor heating safety switch, thermostat, pressure
switch, etc.) may signal an external problem and stop
the heat pump.
- Connect the external component to input EX3 (fi g. 45,
page 39).
• 230 V on input EX3 = heat pump stopped
(system displays Error 369).
