2.2 THERMOSTAT
2.2.1 Explanation of the icons
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.
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 connection
The thermostat is successfully connected to the
RF Receiver.
Low battery
It is necessary to replace the batteries immediately.
RF communication error
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.
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
with your installer if this does not fix the problem.
Defective thermostat
The thermostat is defective and needs to be
replaced.
2.2.3 Night temperature reduction
F77
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 5°c is suggested, but this depends on
the heating system and the amount of insulation of the building.
The text F77 is displayed in addition to this icon
when communication with the YUTAKI unit has
failed for more than 180 seconds.
No power to the thermostat
2.2.4 Installation menu
If the thermostat screen appears blank after initial
installation, then check whether the protective film
has been removed from the batteries. Otherwise,
try replacing the batteries.
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.
