START-UP
Make sure that ALL DIP SW on the interface card 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 EX1, EX2 and EX3 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".
Make all the specific adjustments to the setting (configuring the installation).
-
OK
- Press the key
- Hold down the key
Confirm with the key
-
Parameter the heat pump's setting (See "„ FUNCTION TABLE of 2-3 CONTROL SETTING".).
On commissioning (or the case of error 10), the electrical backup heaters may 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 avoid this situation, the sensor must be connected correctly.
Re-initialise line 8703 (commissioning level, Consumer diagnostic menu).
