Switching the unit on
To switch the unit on in cooling mode, proceed as follows:
Press the D key for approximately 5 seconds, the G LED will
1
be displayed.
To switch the unit on in heating mode, proceed as follows:
Press the C key for approximately 5 seconds, the F LED will
1
be displayed.
In both cases an initialization cycle is started, the L LED, the M LED,
the & LED and the é LED will light up depending on the programmed
thermostat function.
In case the & LED or the é LED is flashing, it indicates that there is a
compressor 1 or 2 startup request. The compressor will start after the
timer has reached zero.
NOTE If remote on/off control is enabled, refer to "Selecting
local or remote on/off control" on page 12.
2 When the unit is started up for the first time, or when the unit has
been out of operation for a longer period, it is recommended to
go through the following checklist.
Abnormal noise and vibrations
Make sure the unit does not produce any abnormal noises or
vibrations: check the fixations and piping. If the compressor
makes any abnormal noises, this may also be caused by an
overcharge of refrigerant.
Working pressure
It is important to check the high and low pressure of the
refrigerant circuit to ensure the proper operation of the unit and
to guarantee that the rated output will be obtained.
For reference, the average saturated temperature of R410A in
relation to the pressure readout can be found in "Annex I" on
page 17.
The pressures measured will vary between a maximum
and minimum value, depending on the water and outdoor
temperatures (at the moment of measurement).
3 If the unit does not start after a few minutes, consult the actual
operational information available in the list of direct parameters.
Also refer to the chapter "Troubleshooting" on page 15.
In case of remote on/off control (h07=1), it is recom-
NOTE
mended to install an on/off switch near the unit in
series with the remote switch. The unit can then be
switched off from either place.
The selection of cooling mode or heating mode can
only be carried out at startup. Selecting an opposite
mode without switching the unit off is impossible.

Press the C or D key to select the required parameter
2
group.
Press the B key to enter the selected parameter group.
3
Press the C or D key to select the required parameter.
4
Press the B key to consult the selected parameter.
5
Press the C or D key to raise, respectively lower the
6
setting of the selected parameter. (Only valid for read/write
parameters.)
Press the B key to confirm the modified setting.
7
OR
Press the A key to cancel the modified setting.
Press the A key to return to the parameter group.
8
Press 2 times the A key to return to the main display.
9
If during the procedure no buttons are pressed for 30 seconds, the
displayed parameter code or value will start flashing. After another
30 seconds without pressing any buttons, the controller automatically
returns to the main display without saving any modified parameter.
How to consult the "sensor readout menu" parameters
For an overview of the menu structure, refer to "Menu overview" on
page 18.
The b01/b02/b03 parameters are part of the "sensor readout
menu".
Press the C or D key in the main display.
1
The b01 parameter is displayed.
In case no buttons are pressed, the value of the b01 sensor will
be displayed until C or D is pressed again to select
another parameter (b02 or b03).
Press the A key to return to the main display.
2
If during the procedure no buttons are pressed for 30 seconds, the
displayed parameter code or value will start flashing. After another
30 seconds without pressing any buttons, the controller automatically
returns to the main display.
Adjusting the cooling temperature setpoint
Modify the r1 cooling setpoint parameter.
1
This is a direct parameter, refer to "How to consult and modify the
direct parameters" on page 8.
NOTE When dual setpoint is enabled (refer to "Selecting dual
setpoint control" on page 12).
