Boiler Connection - Fujitsu WOxK112LCT Design & Technical Manual

Interconnection between the outdoor
•
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.
