F7: Ventilator function at cooling operation
At F7=1 the ventilator is always on (except possibly
for a defrosting process, see parameter F4).
At F7=2 the ventilator is always on or off together
with the compressor.
At F7=3 the ventilator is switched on whenever the
compressor is on and the evaporator temperature
(sensor F2) is below the refrigerating chamber
temperature (sensor F1). The ventilator is switched
off whenever the evaporator is switched off, whereas
parameter F5 is not active. In the case of sensor
error the ventilator reacts as in the setting F7=2.
F8: Ventilator revolution number at normal
cooling operation
This parameter determines the ventilator revolution
number at normal cooling operation.
F9: Ventilator revolution number at defrosting
This parameter determines the ventilator revolution
number at defrosting.
F10: Kick-start (in seconds)
If necessary, this is an option to set a time during
which the ventilator starts with the maximum number
of revolutions for stable operation. This parameter is
only efficient, if the ventilator is newly started.
b1: Function key A
b2: Function key B (if available)
At setting = 0 the respective key has no function.
At setting = 1 the controller is switched to standby
mode
At setting = 2 the key is linked with the function
“setpoint Y1 for the thermostat 2 indicate/adjust”
At setting = 3 a relay (indicated with parameter Ux)
can be switched on or off directly with the key. In
standby mode the key is locked and the
corresponding relay switched off. After restarting the
corresponding relay remains switched off.
At setting = 4 a relay (indicated with parameter Ux)
is switched despite of
the standby mode.
The
condition of the exit is maintained until the key is
pressed again or until it is changed by an external
switching entrance. After net interruption, the
condition before power failure is re-installed.
At setting = 5 the actual value of sensor 2 can be
indicated. At setting P4=0 the key has no function.
b3: Function key 3 (standby)
At setting b3=0 the function of the key can be
deactivated.
b11: Function external entrance E1
b12: Function external entrance E2
b13: Function external entrance E3
b14: Function external entrance E4
Depending on existing hardware there are no or not
all external entrances.
At setting = 1 the controller is switched to the
standby mode.
At setting = 2 defrosting of both controllers is started.
At setting = 3 a relay (indicated with parameter Ux)
is switched on or off directly. In standby mode it is
locked and the relay is switched off.
At setting = 4 a relay is switched directly (indicated
with parameter Ux) regardless of the standby mode.
After net interruption the condition before power
failure is re-installed.
U1: Exit connection K1
U2: Exit connection K2
U3: Exit connection K3
U4: Exit connection K4
Depending on existing hardware there may not be
all output relays. This parameter assigns the
respective relay to the internal controller exits, to
function key 1 or 2, to one external entrance or the
buzzer.
At setting =6 or =7 the relay is switched manually. It
changes its condition with each pressure of the key
and adopts the condition of the respective switching
entrance whenever the latter changes. If the
corresponding key or switching entrance has not
been released for this function (see parameters b1,
b2 and b11 to b14), the relay remains switched off.
The buzzer connection in its function is comparable
to the alarm connection. The buzzer, however, can
be switched off with the DOWN key.
