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.
