2 12 Start-up
-Make sure that ALL DIP SW are OFF before starting
up. DIP SW shuold be set OFF for normal operation.
Power supply to the hydraulic unit must be turned off
while toching DIP SW.
-Close the installation’s main circuit breaker.
On first commissioning (or in winter), in order to
allow the compressor to pre-heat, engage the
installation’s main circuit breaker (power supply
to the outdoor unit) some hours before starting
up the tests.
-Engage the start/stop switch.
To ensure that inputs EX4, EX5 and EX6 operate
correctly : Check that the live-neutral polarity of
the electrical supply is correct.
When the power is switched on and every time that the
ON/OFF button is switched off and then switched on
again, the outdoor unit will take approximately 4 minutes
to start up, even if the setting is requesting heating.
The display can show error 370 when the
appliance (re)starts. Do not be concerned, the
communication between the outdoor and hydraulic
unit will re-establish itself in a few moments.
During the regulator initialisation phase, the display
shows all the symbols and then "Data, update" and then
"State heat pump".

).
On commissioning (or the case of error 10), the electrical
backup heaters are liable to start up even if the outdoor
temperature at the time is above the heaters’ trigger
temperature.
The regulating system uses an average initial outdoor
temperature of 0°C and requires some time to update
this temperature.
To mitigate this situation, the sensor must be connected
correctly. Re-initialise parameter 8703 (implementation
level, consumer diagnostic menu).
