When the temperature is higher than the set cut-out
+ the set dierential, the compressor relay will be cut-
in. It will cut-out again when the temperature comes
down to the set cut-out limit.
Setpoint. The thermostat’s cut-out value when the
given thermostat band is in use
When the temperature is higher than the set cut-out
+ the set dierential, the compressor relay will be cut-
in. It will cut-out again when the temperature comes
down to the set cut-out limit
Setpoint limitation - The controller’s setting range for
the thermostat setpoint may be narrowed down, so
that too high or too low values are not set accidental-
ly - with resulting damages.To avoid a too high set-
ting of the setpoint, the max. allowable reference val-
ue may be lowered
Setpoint limitation - The controller’s setting range for
the thermostat setpoint may be narrowed down, so
that too high or too low values are not set accidental-
ly - with resulting damages.To avoid a too low setting
of the setpoint, the min. allowable reference value
may be increased
Night setback value.The thermostat’s reference will be
the setpoint plus this value when the controller
changes over to night operation.
Heat function. Set the width of the Neutral Zone for
changeover from cooling to heating
Time delay on transition from refrigeration phase to
heating phase (there is no time delay on transition
from heating phase to refrigeration)
Melt function. Only for control of MT cases/rooms (-5
to +10°C). The function ensures that the evaporator
will not be blocked by ice crystals. Here you set how
often the function is to stop the refrigeration and
hence transform the ice crystals to water.
Melt period. Here you set how long an ongoing melt
function is to last
