5.3.4 Programmable room thermostats & setting variable internal temperatures.
Central heating is controlled by the heating curve programmed into the Termo E boiler and fine tuned by a room
thermostat.
With modern central heating controls such as a programmable room thermostat it is possible to set different room
temperatures at different times of the day. e.g. to have a lower temperature set during the night. If this system is
used the heating curve selection is unchanged and the offset of the heating curve should be set to the highest
room temperature required during the day. (See paragraph above). The programmable room thermostat is then
set according to the manufacturers instructions to set lower temperatures when required.
When setting variable temperatures please be aware that the heating system will take some time to heat up from cold and
similarly will remain hot for some time after the temperatures are reduced or the system is switched off. To optimize comfort
levels and minimize energy consumption it is suggested to activate the boiler 30 minutes before the set temperature in heating
system is required and to reduce temperature or switch off 30 minutes before the lower temperature is desired.
5.5 Protection from freezing
To protect the entire central heating system from freezing (if a building is to be left empty for an extended period
of time during cold weather), set the boiler to standby mode. The room thermostat or central heating programmer
must be set to freezing protection mode (usually 5 to 7˚C, depending from room thermostat manufacturer), this
will allow pump to circulate heated medium through central heating system.
6. Recommended annual checks (all boilers)
The safety valve should be checked annually, preferably before the heating season to ensure correct operation
and avoid accumulation of lime scale. It is not recommended to annually drain the system to protect the system
from freezing as refilling with fresh water will increase the risk of limescale attack
We recommend inspection of the boiler once a year by an authorized service engineer. This service is not
included in the guarantee. During the inspection all electric and water connections should be tightened, the
system should be vented and – if necessary – filled up, valves and general functionality of the device and safety
valves should be checked.
When cleaning the product do not use an aggressive liquid as e.g. gasoline, kerosene or solvent. For the external
shell and decorative cover, liquid for cleaning plastics or dish washing media may be used. Control panel should
be cleaned with dry or moist cloth (not wet).
