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: absolute/relative setpoint
available as of version 1.60:
If
=0, the setpoint
is an absolute value, if
=1 the setpoint of control circuit 2 is the sum of
and the actual setpoint
/
/
.
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
