10.4 Switching difference (d)
This parameter defines the switching difference (hysteresis) of
the control function. If the current actual temperature lies
above the desired temperature by the value set here, the
output will be switched off. If the actual temperature falls below
the setpoint by the value set here, the output will be switched
on (for each heating and de-energized closed drives operating
mode).
The factory setting for the switching difference is ±0.2° C.
10.5 Frost-prevention temperature (F)
This function is the only way of permanently activating the
frost-prevention temperature. This prevents an inadvertent
activation from causing damage.
The frost-prevention temperature that was set under the
temperature levels can be activated or deactivated here (On /
OFF). The frost prevention function will be activated when this
setting in the "On" position is confirmed with SET.
To deactivate, the corresponding input must be confirmed with
"OFF". After deactivating the frost prevention function, the
automatic control device operates in the permanent lowering
operation.
10.6 Upper limit temperature (o)
This parameter allows a specific upper limit to be set for
temperature on the external sensor. When the limit function is
activated (heating operating mode with limit function and de-
energized closed actuator operation selected), the output will
be deactivated when the temperature measured on the
external sensor exceeds the temperature set here.
The possible setting range is +25° C to +50° C.
The factory setting for the upper limit temperature is 50° C.
The limit function does not have any switching difference, i.e.
switching occurs immediately when the limit value is exceeded
or undershot. Similarly, the minimum switching duration is
ignored.
10.7 Lower limit temperature (u)
This parameter allows a specific lower limit to be set for
temperature on the external sensor. When the limit function is
activated (heating operating mode with limit function and de-
energized closed actuator operation selected), the output will
be deactivated when the temperature measured on the
external sensor falls below the temperature set here.
The possible setting range is +12° C to +35° C.
The factory setting for the lower limit temperature is 14° C.
The limit function does not have any switching difference, i.e.
switching occurs immediately when the limit value is exceeded
or undershot. Similarly, the minimum switching duration is
ignored.
