2.2.1 Explanation of the icons
Setting temperature
The figure appearing on the screen corresponds
to the setting temperature, instead of the current
room temperature.
Heating on
Heating is demanding, and thus the heat pump
should be in operation, either intermittent or
continuous.
RF receiver binding
The thermostat is on binding process with the RF
receiver.
RF receiver connection
The thermostat is successfully connected to the
RF receiver.
Setting modification indication
In case that RF receiver connection symbol
is surrounded by this symbol means that setting
temperature has been updated from central
application.
This symbol is not displayed in case setting
temperature has been modified by turning the
thermostat wheel.
RF communication error
These icons flash to indicate that the signal from
the RF Receiver is not properly received. Check
that the RF Receiver is powered on, and consult

2.2.2 Setting of room temperature
The current room temperature is shown in the display. The
setting temperature can be changed by turning the dial to
the right to increase temperature, and to the left to reduce
temperature. The setting temperature changes in 0.5ºC steps,
one for each 'click' as the dial is turned.
The display changes to current room temperature again after
five seconds have passed. Then the thermostat tries to maintain
the set temperature as accurately as possible. The setting
temperature can be checked by turning the dial one 'click' to the
left or right. It will flash up for a few seconds, before returning to
the display of room temperature again.
2.2.3 Night temperature reduction
It is recommended to set the thermostat to a lower temperature
at night and during absence periods, as it helps to save energy.
In general a reduction of 3°C is suggested, but this depends on
the heating system and the amount of insulation of the building.
2.2.4 Installation menu
The single zone thermostat has an installation menu that is used
to set the maximum and minimum temperature limits.
The maximum temperature that can be set on the thermostat is
35ºC and the minimum temperature is 5ºC.
2.2.5 ON/OFF Switch
The temperature dial is used to turn the system ON and OFF.
Turn the dial to the left until the displayed temperature is lower
or equal than 10 ºC in order to turn the system off. Turn the dial
to the right until the displayed temperature is more than 10 ºC in
order to turn the system ON again.
2.2.6 Activation of the installation menu
