9.2.3. Switching between cooling and heating
Switching the unit between cooling and heating can be done in
2 different ways. This will depend on how the temperature is
controlled, i.e. based on room temperature or based on leaving water
temperature.
If the unit control is based on room temperature (external room
thermostat or remote controller room thermostat), switching
between cooling and heating is done through the remote
controller by pushing button 32 (refer to "Name and function of
buttons and icons" on page 29). For more information about
selecting cooling and heating operation, refer to "Space cooling
operation ( )" on page 30 and "Space heating operation ( )" on
page 31.
If the unit control is based on leaving water temperature, we
suggest using the ABC terminals on the outdoor unit (possible
for EWYQ models only). The location of the terminals is shown
in the following figure.

position.
(
is the position of the switch)
2 It is recommended to re-initialise the communication of the
module by pressing BS5 (reset button) for 5 seconds.
3 When the voltage free contact between terminals A and C is
open, the unit is in cooling. Closing the contact between A and C
will switch the unit to heating.
9.2.4. Field settings on the remote controller
The unit should be configured by the installer to match the installation
environment (outdoor climate, installed options, etc.) and user
demand. Therefore, a number of so-called field settings are available.
These field settings are accessible and programmable through the
remote controller.
Each field setting is assigned a 3-digit number or code, for example
[5-03], which is indicated on the remote controller display. The first
digit [5] indicates the 'first code' or field setting group. The second
and third digit [03] together indicate the 'second code'.
A list of all field settings and default values is given in the "6.1.1. Field
settings on the remote controller" on page 41. In this list we provided
for 2 columns to register the date and value of altered field settings at
variance with the default value.
A detailed description of each field setting is given under
"9.2.6. Detailed description" on page 20.
9.2.5. Procedure
To change one or more field settings, proceed as follows.
1 Press the button for a minimum of 5 seconds to enter FIELD
SET MODE.
The icon (3) will be displayed. The current selected
field setting code is indicated (2), with the set value
displayed to the right (1).
2 Press the button to select the appropriate field setting
first code.
3 Press the button to select the appropriate field setting
second code.
4 Press the button and button to change
the set value of the select field setting.
5 Save the new value by pressing the button.
6 Repeat step 2 through 4 to change other field settings as
required.
7 When finished, press the button to exit FIELD SET MODE

It is possible that the leaving water temperature becomes
lower than the set point if the unit is controlled by room
temperature.
