• Interconnection between the outdoor unit and the
hydraulic unit :
Comply with the correspondence between the markings
on the hydraulic unit’s terminals and those on the outdoor
unit when connecting the interconnection cables.
A connection error could cause the destruction of one or
other of the units.
• Electric back-ups :
If the heat pump is not installed with a boiler
connection :
-Connect the electrical supply for the back-ups
(terminals 20, 21, 22 and 23) to the electrical panel.
• Boiler connection :
-Please refer to the instructions supplied with the boiler
connection kit.
-Please refer to the instructions supplied with the boiler.
• Domectic hot water tank :
If the installation is fitted with a DHW tank with electrical
back-up heating :
-Please refer to the instructions supplied with the DHW kit.
-Please refer to the instructions supplied with the DHW tank.
• Second heating circuit :
-Please refer to the instructions supplied with the
second circuit kit.
• Contract with the power provider :
The heat pump’s operation can be controlled to suit
special contracts (e.g. off-peak, day/night).
In particular, domestic hot water (DHW) at Nominal
temperature will be produced during the off-peak hours
when electricity is cheaper.
-Connect the "Power Provider” contact to input EX5.
-Set the parameter (1620) to "Off-peak hours".
• 230V on input EX5 = "Peak hours" information activated
(Basic setting / Modification possible line 5989,
menu Configuration).
• Power limitation or EJP (peak day removal) :
Power limitation is intended to reduce electrical
consumption when this is too high compared to the
contract with the power provider.
-Connect the power limiting device to input EX4, the
back-ups for the heat pump and the DHW stop in the
event of over-consumption by the dwelling.
• 230 V on input EX4 = power limitation in progress.
(Basic setting / Modification possible line 5987,
menu Configuration). (Operating line 2920)
• External faults the heat pump :
Any component of carryforward of information
(thermostat, pressure switch, etc.) may signal an
external problem and stop the heat pump.
-Connect the external component to input EX6.
• 230 V on input EX6 = stoppage of heat pump
(the system displays Error 369).
-In the case of a heated floor, Connect the floor heating
safety device into the connector of the floor heating
pump (QX3 - circuit 1, QX23 - circuits 2).
