temperature is between -10°C to +50°C, then it is recom-

mendable also to adjust the hysteresis (C) according to the

requested regulating range.

As an example if the temperature is set at 18°C and the

hysteresis at 3°C the thermostat will switch on at 18°C and

off at 21°C.

For controlling of room temperature the Hysteresis is rec-

ommended to the set point of 1°C.

Minimum Temperature Limiter

When the thermostat is used in connection with snow and

ice melting systems, it is recommendable also to use and

adjust the minimum temperature limiter (B) which ensures

both an upper and lower temperature range in between

which the thermostat allows the system to heat.

The requested maximum temperature range has to be

between -10°C to +50°C and the requested minimum tem-

perature range has to be between -10°C to +5°C.

An link between terminal 9+10 must be connected to acti-

vate the use of the minimum temperature feature when the

thermostat controls snow and ice melting in gutters, valley

gutters and down pipes, where the waste of unnecessary

energy must be avoided. In particular by extremely cold

weather where flowing water or moisture does not occur.
