TRQ 21 W
5.3.3 Operating Reserve
After at least three days of operation from
the commercial power source, the timer has
an operational reserve available of approx.
50 hours. During this period, the timer conti-
nues to run on a rechargeable battery.
Take care that the power supply is not inter-
rupted for longer than 50 hours (also when
the heater is switched off). Deep discharging
shortens the service life of the rechargeable
battery!

Error Localisation

Error
Room temperature setting is
not achieved.
Room temperature setting is
exceeded.
Room temperature variations
too large.
6
Switch off the heater before ventilating the
room. Always ventilate briefly but intensively.
Avoid continuous ventilation.
A reduction in the room temperature by 1°C
can save up to 5 % of the energy used. Do
not allow the room temperature to sink below
15° C, however, since strong heating up
consumes more energy than uniform hea-
ting.
With good insulation of the building, it is pos-
sible that the reduced temperature setting is
not reached. Energy is saved, however, sin-
ce the heater remains switched off. In this
case, the switching time for reduced mode
can possibly be set earlier.
For subsequent installation of a thermostat
in a room with thermostatically controlled ra-
diators, the thermostatic valves in this room
must be opened completely. Otherwise, the
thermostatic valves restrict the heating alt-
hough the heater is switched on continuous-
ly.
Cause
Boiler thermostat on the hea-
ter is set too low.
or
Thermostatic valves are in-
stalled in the room where the
thermostat is mounted.
Mounting position of the ther-
mostat is unfavourable, for
example, exterior wall, near
a window, etc.
Intermittent effect of external
warmth on the thermostat,
e.g., sunshine, room lighting,
TV or fireplace, etc.

Tips for Saving Energy
