To access the electrical connections hub:
• Remove the cover and the shell.
• Remove the cover of the appliance by removing the screws which
fix the shell onto the lower part of the appliance.
• Remove the black protective cover from the electronics board.
The power supply should comply with all regulations in effect in
the country of installation, as well as the NFC 15-100 standard.
A method of disconnection which ensures total power-cut in
Category III conditions should be installed in fixed piping in
compliance with the installation rules.
• an 8A all-pole circuit breaker with a minimum 3mm
contact opening.
• a protective 8A circuit breaker with a 30mA differential.
If the power supply cable is damaged it must be replaced by the
manufacturer, their customer service technicians, or by a qualified
technician to avoid any risk of injury or danger.
4.5 - Electrical connections
4.5.1 - External control
Only a dry contact, voltage-free, external
connection may be used. Otherwise you
risk damage to the electronics board.
Do not connect the heat pump water
heater to wiring from an older water
heater using the peak/off-peak hours contact.
The heat pump water heater must always be
connected to a power supply.
Peak/off-peak control can be managed through
programming or though an independent cable.
Grounding is obligatory.
Power supply is managed through a 230V single-
phase and grounding cable.
The heat pump water heater can be used to continuously
ventilate a room even if the heating cycle is complete.
To stop the fan from operating, connect a timer on a moisture
sensor. Use the same procedure as for the timer switch, but
connect the 2-wire cable to «Input 2» on the electronics board.
- Switch open
= the fan will not operate
- Switch closed = the fan will operate
• Set the regulator to «External control ventilation mode» :
f a n
m o d e 3 .
4.5.1.2 - Controlled ventilation
4.5.1.1 - Peak/off-peak hours contact
To prevent the electrical back-up from running during peak
hours, connect the dry contact originating from the electricity
counter, to terminal 1.
- Switch open = Back-up not allowed to run
- Switch closed = Back-up allowed to run
By choosing load shedding level 0 or 1 (see § «Load shedding»),
you stop the electrical back-up alone from running (load
shedding =1) or the heat pump and the electrical back-up from
running (load shedding = 0).
• Pass a 0,75mm² 2-wire cable with metal tips through a cable
gland at the back of the appliance and bring the end of the
cable around to the electronics board. The other end of the cable
should be connected to the timer switch.
• Insert the 2-wire cable through a grommet from the electronics
box.
• Connect the 2-wire cable to «Input 1» indicated on the electonics
board, having already removed the existing red bridge.
4.5.1.3 - Electricity provider contact
To program the operation of the heat pump water heater during
peak/off-peak hours, it is not necessary to connect the dry contact
to the electricity counter.
It is possible to program scheduled operating times for the heat
pump water heater or of the electrical back-up from the control
panel (see §3.8 Programming).
It is possible to connect the dry contact from the electricity
counter to the heat pump water heater without programming
from the control panel.
- Switch open
=
Load shedding
- Switch closed
=
Normal functioning
The level of load shedding can be chosen from the control panel
of the appliance (see § 5.9.2.4 Load shedding).
By default the electrical resistance does not operate during peak
hours. .
It is not advised to operate the heat
pump water heater during off-peak hours
so as to optimise its functionality.
