• 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 (option)
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 (option)
" If the boiler connection option is used, the
electric boost option must not be connected.
- Please refer to the instructions supplied with the boiler
connection kit.
- Please refer to the instructions supplied with the boiler.
• Domestic hot water tank (option)
If the installation is tted 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.
• 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 EX2.
- Set the parameter 83 to "Off-peak hours".
• 230V on input EX5 = "Peak hours" information
activated.
• Power shedding 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 EX1, 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 oor; insert the heated oor
thermal safety fuse son the binding of heating-cooling
oor circulation pump.
