Temperature blocking:
In order to lock the set temperature, insert pegs on both sides of the "stop rib".
Temperature setting:
The factory setting of the thermostat is arranged so that the number 3 on the graduated scale gap
corresponds to a room temperature of 20°C.
Should this setting be inadvertently disturbed, the following procedure should be undertaken in
order to restore it:
– First remove the frame cover and pull-off the graduated scale cap.
– Turn the centre adjustment screw clockwise until stop, and then turn it anticlockwise until the
factory red paint marks falls in line with the "stop rib".
– Then replace the graduated scale cap so that the number 3 also falls in line with the "stop rib".
– Thus the original setting is restored.
– Finally replace the gram cover (Illustration 6).
