between the evaporator and the cold store sensor
is to be used for controlling the fan. The control
setpoint and hysteresis are defined via parameters
and
.
Fan mode defrosting
In this parameter, you can define if the fan is to be
on or off during defrosting. This parameter will not
be effective in temperature-controlled fan mode
[
=4 or 5].
Delay after compressor On
In order to avoid mains overload by starting the
compressor and fan at the same time, you can
define a delay for the fan in this parameter. It will
not be effective in temperature-controlled fan mode.
Delay after defrosting
At the end of a defrosting cycle, the fan will be
switched on after the delay set in this parameter.
This parameter will be effective in all fan modes set
up.
Drip interruption time (if
=2)
If the fan runs in continuous mode, there is low
temperature variation at high atmospheric moisture.
In operation mode "with compressor on", the
temperature variation will be greater while the
atmospheric moisture is lower. This parameter is to
enable a combination of both advantages. The fan
runs in continuous mode and is switched off for the
time specified here when the compressor is
switched off. This enables the moisture
accumulating at the evaporator to drain off.
Control offset evaporator
sensor (for
=4 or 5)
If [
=4] the following applies: The setpoint for
control circuit 1 (
or
) forms the basis. If the
evaporator temperature is below the setpoint, the
evaporator fan will be switched on. This switching
point can be shifted by the value defined here.
If [
=5] the following applies: The temperature
difference between cold store (sensor from
) and
evaporator temperature (sensor from
)
determines the switching point for the evaporator
fan. If the evaporator temperature is below the cold
store temperature, the evaporator fan will be
switched on. This switching point can be shifted by
the value defined here.
Hysteresis (if
=4 or 5)
The control hysteresis is always set above the
theoretical switching point.
Assignment of evaporator sensor
With this parameter, you can set which sensor input
is to be used as the evaporator sensor. The
selected sensor must be set up accordingly in the
parameters.
Condenser fan: setpoint
Only effective if [
=3]. If the value defined here
is exceeded, the condenser fan will be switched on.
Condenser fan: switching hysteresis
Only effective if [
=3]. The hysteresis is set on
one side above the setpoint of parameter
.
Condenser fan:
Delay after compressor start
On-delay of condenser fan after activation of the
compressor.
Condenser fan:
Delay after compressor stop
Off-delay of condenser fan after shut-down of the
compressor.
Function of condenser fan
0: no function, i.e. condenser fan is off
1:
condenser fan on at all times
2:
condenser fan on if compressor is on
3: condenser fan controlled via setpoint in
parameter F51. In the case of a sensor fault, the
fan behaves like defined in [
=2].
4: like 3., but the fan is controlled continuously via
a voltage output
The proportional range is defined in parameter
.
