INAL CHECK AND TEST RUN
Final check
Before switching on the unit, read the following:
■
When the complete installation and all necessary settings have
been carried out, be sure that all panels of the unit are closed. Is
this not the case, inserting your hand through the remaining
openings can cause serious injury due to electrical and hot parts
inside the unit.
■
The service panel of the switch box may only be opened by a
licensed electrician for maintenance purposes.
In order to purge most of the air out of the system perform a pump
operation as described below:
1 Change field setting [E-04]
The default value is 0.
■
When changing the setting to 1, the pump will operate at low
speed (pump only, the unit will not operate).
■
When changing the field setting to 2, the pump will operate at
high speed.
2 When air purging is finished, change the field setting back to 0.
It is the responsibility of the installer to make sure that the air is
purged out of the unit and system.
Test run
The installer is obliged to verify correct operation of the indoor and
outdoor unit after installation. Therefore a test run must be performed
according to the procedures described below. At any time it is
possible to check correct operation of space heating and domestic
water heating.
Temperature read-out mode
On the remote controller, the actual temperatures can be displayed.
1 Push and hold the button for 5 seconds.
The leaving water temperature is displayed (icons and
and are blinking).
2 Use the and buttons to display:
• The entering water temperature (icons and are
blinking and the icon is flashing slowly).
• The indoor temperature (icons and are blinking).
• The outdoor temperature (icons and are blinking).
• The hot water supply tank temperature (icons and are
blinking).
3 Push the button again to leave this mode. If no button is
pressed, the remote controller leaves the display mode after 10
seconds.
Procedure for space heating
1 Check the leaving water and entering water temperature through
the remote controller read-out mode and write down the
displayed values. See "Temperature read-out mode" on
page 34.
2 Push the button 4 times so the icon will be displayed.
3 Perform the test as follows (when no action is performed, the
user interface will return to normal mode after 10 seconds or by
pressing the
button once):
To test the space heating operation push the button to start
the test run operation.
4 The test run operation will end automatically after 30 minutes or
when reaching the set temperature. The test run operation can
be stopped manually by pressing the
button once. If there are
misconnections or malfunctions, an error code will be displayed
on the user interface. Otherwise, the user interface will return to
normal operation.
5 To resolve the error codes, see "Error codes" on page 37.
6 Check the leaving water and entering water temperature through
the remote controller read-out mode and compare them with the
values noted with step 1. After 20 minutes of operation an
increase of the values should confirm the space heating
operation.
Procedure for domestic water heating
1 Check the domestic hot water tank temperature through the
remote controller read-out mode. See "Temperature read-out
mode" on page 34.
2 Push the button for 5 seconds.
The icon will start blinking with 1 second intervals.
3 Keep the unit operating for 20 minutes and check the domestic
hot water tank temperature through the remote controller again.
An increase of the value with 5°C should confirm the domestic
water heating operation.
4 The operation will stop if the tank storage temperature has been
reached.
NOTE When using thermostatic radiator valves, make sure to
open all valves during air purging operation.
NOTE
When the indoor and outdoor unit are powered on for
the first time, an initialisation takes place. This will take
maximum 12 minutes.
When using the remote controller during the
initialisation, an error code (
UH
) will be displayed.
NOTE
■
During the first start up of the unit (the first 48
hours of compressor running), it might happen
that the noise level of the unit is higher than
mentioned in the technical specifications. This is
not an abnormal event.
■
Start up of the unit in space heating mode is only
possible when the outdoor ambient temperature is
lower than 20°C. Refer to "[9-02] Thermo ON/OFF
admission" on page 24 how to increase this
temperature limit.
NOTE To display the last resolved error code, push the
button 1 time. Push the
button again 4 times to
return to normal mode.
NOTE It is not possible to perform a test run if a forced
operation from the outdoor unit is in progress. Should
forced operation be started during a test run, the test
run will be aborted.
