Control circuit 2
(password-
protected)
Assignment of sensor for independent 2nd
control circuit (thermostat)
With this parameter, you can set which sensor input is
to be assigned to the 2
nd
control circuit.
Control circuit 2: setpoint
Here, you can set the setpoint for the 2nd control
circuit (thermostat). If a button is parameterised
accordingly, the setpoint can also be viewed and set
up via this button directly.
Control circuit 2: switching mode
Heating contact or cooling contact.
Control circuit 2: hysteresis
In this parameter, you can specify the control
hysteresis. A small hysteresis enables exact control,
but will result in frequent switching of the relay.
Control circuit 2: Hysteresis mode
With this parameter you can define if the hysteresis will
be active at the corresponding switching point
symmetrically or on one side only. In the case of a
one-sided hysteresis, the hysteresis will be active
below the setpoint in the case of the heating function
[[
=0] and above the setpoint in the case of the
refrigerating function [
=1]. In the case of a
symmetrical hysteresis, there is no difference.
Control circuit 2: upper setpoint limitation
Control circuit 2: lower setpoint limit
With these parameters, you can limit the setting range
of setpoint
to avoid that the end user does not
enter non-permissible values.
Control circuit 2: Function in the case of sensor
fault
Here, you can define if, in the case of a fault, the
addressed output contact will open or close.
Control circuit 2: Defrosting interval
The defrosting interval defines the time after which a
defrosting operation is started. As soon as the
defrosting cycle is triggered, the defrosting interval
starts again. In this way, periodic defrosting at a fixed
time interval is ensured.
Control circuit 2: Defrosting time limitation
Here, you can set the max. time in which the defrosting
operation must be completed.
Password of parameter level
With this parameter, you can set the password for
parameter level
.
