Prevent freezing of your central heating installation

When the thermostat has been switched off for both the Com-

fort setting and the central heating (the (!) symbol is visible),

the thermostat will keep room temperature at a minimum of

5°C (Frost prevention). This is the case when ‘UIT’ (OFF) has

been selected in the central heating menu and the tapwater

menu. However, it is advisable not to set the thermostat lower

than approx. 12°C. This reduces the risk that parts of your cen-

tral heating system or water pipes will freeze considerably, in

particular when the pipes are located in a frost-exposed area.

6 Trouble-shooter

This chapter explains some faults and questi-

ons you may have regarding the functioning of

the thermostat.

Questions / complaints about your heating installation

Explanations are given in respect of likely questions.

Faults

Explanations are also given in respect of faults usually indica-

ted by the

symbol. Check whether you can solve the faults

yourself and call your installer if necessary. These faults may

also be caused by a connected boiler. Therefore, also check

the boiler’s display screen and refer to the corresponding

manual.

Questions / complaints about your

heating installation

Heating up takes a long time in the morning.

• Are all radiator taps open? Check it out.

• Is the night temperature not set too low? You may increase

the current night temperature by 1 or 2 degrees to prevent

slow heat up.

• Consult your installer if the complaint persists.
