<h10.2> (10.2 ° C) - example.
c) Control of external heat-source.
<F 1> = normal auto-reverse cycle
(cool/heat) without external heat source.
<F 2> = autoreverse cycle operation with
external heat assistance. In that case the oulet
connectors <HEAT> on the Cabin controller
card are activated together with the
<VALVE> oultlet when heat cycle is select-
ed. This external heat source can be an AC
heating element or any other source such as
ceramic heaters etc
<F 3> = heat operation with external heat
source only. Inthat case the <VALVE> outlet
on the controller card is not activated and
only the <HEAT> connectors are opera-
tional.
c) Automatic dehumidification
while
absent.
Factory default setting : <d 0>
0 = non active
1 = 1 cycle per 24H
2 = 2 cycles per 24H etc
d) display time of secondary functions
(F/Blower key) by periods of 20 seconds.
Factory default setting : <t 1> = display
time 20 seconds
Special features - 2000/2004 Series :
See beginning page 4.
Continued features - 2000 Series :
A) Automatic blank/sleep mode
- program-
mable time delay. Factory default : 15 min-
utes. While in blank/sleep mode the cycle
LED flashes discretely every 20 seconds. To
go back to normal operation push any key.
B) Real time modification of all blower
speed settings.
It is now possible to alter all speed settings (1
to 5) before actually putting the system into
service. To do so entrer programming mode
with set-point at 15° C.; proceed to line<6> =
speed 5 (max).
Alter value and blower speed will immedi-
ately change in real time. When satisfied go
to following line <7> = speed 4 and do the
same.
Proceed until lowest speed N° 1 and go back
again to speed N° 5 if not satisfied.
When all speeds are programmed according
to need, validate by pushing on/off key
(<memo> will be displayed briefly).
Attention : Never program speeds so
low that the blower is in danger of
stopping or will not re-start at that
setting. This will inevitably entail
motor-windings burn-out and will
not be covered by WEBASTO war-
ranty.
Programming of the CAB - 230V
controller cards :
To access hidden programming functions
raise set-point temperature to 29° or lower to
15° and push On/Off key.
Then push both set-point keys simultaneous-
ly for approx. 3 seconds and you will enter
programming mode as explained here-after.
Validation is obtained by pushing the
F/Blower key and by going to the next pro-
gramming line.
Programming codes available by raising the
set-point to 29° C :
Code <4>
: Calibration of chilled water temp
Code <5>
: time delay in minutes before the
display goes into sleep mode.
Code <7>
: Calibration of room temperature
read-out.

: Program version
Programming codes available when lowering
the set-point to 15° C :
Code <1> -
factory setting : 0 - infra-red
remote control :
0 = infra-red remote control disabled
1 = infra-red remote control active
Code <2>
: Blower type : Centrifugal or
Cross-Flow. Factory default : 1
0 = centrifugal blowers only
1 = centr cross-flow
Code <3>
: continuous blower operation = 1
thermostatic blower control = 0
Code <4>
: integrated air-sensor = 1
external air-sensor = 0
Code <5>
: display in Celsius or Fahrenheit
default value = 0
0 = Celsius read-out
1 = Fahrenheit read-out
Code <6>
: calibration speed N° 5 (max)
