unit and the indoor unit
Comply with the correspondence between the
markings on the indoor 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 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 or / and Regulation extension
kit.
Contract with the power provider
•
The heat pump’s operation can be controlled to suit
special contracts (e.g. Low-tariff, 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
-
EX2.
Set the parameter line 1620 to “Low-tariff”.
-
230V on input EX2 = “Peak hours” information
-
activated.
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 EX,
-
the back-ups for the heat pump and the DHW
stop in the event of over-consumption by the
dwelling.
230 V on input EX1 = power limitation in
-
progress.
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 EX3.
-
230 V on input EX3 = 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.
