During low-voltage cut-out the display panel
will show the 3 letters
Programming of a cut-out level below 195 V
is done at the entire risk of the operator. It
should be noted that almost all compressor
manufacturers decline all responsibility for
defects resulting from operating the com-
pressors below 195V AC.
Code <1> - factory setting : 0 - infra-red
remote control :
0 = infra-red remote control disabled (in this
mode no interference is possible with other
infra-red commands)
1 = infra-red remote control active
Code <2> : Blower type : Centrifugal or
Cross-Flow. Factory default : 1
0 = centrifugal blowers only
1 = centrifugal + cross-flow
Code <3> - pre-programmed value : 1 -
basic choice of blower control :
0 - thermostatic control of blower operation
i.e. blower operation will be interrupted ther-
mostatically when reaching the appropriate
set-point.
1 - un-interrupted blower operation regard-
less of the thermostatic control.
Code <4> - factory setting : 1 - Choice
between integrated air sensor and external air
sensor :
1 - air sensor integrated in digital display
0 - external air sensor
Code <5> - Celsius or Fahrenheit display -
factory setting : 1
0 = Celsius read-out
1 = Fahrenheit read-out
Code <6> : modification speed N° 5 (max)
Code <7> : idem speed N° 4
Code <8> : idem speed N° 3
Code <9> : idem speed N° 2
Code - factory setting : 0 - access code
for programming mode.
0 = no access code required
1 to 99 = access code/number activated
*) Factory access code : in case the system is
blocked and the access code cannot be found,
you can acces the programming line by using
the factory code number : 64

DIPSWITCHES :
The TCC controller card has a dipswitch
arrangement which should be set and main-
tained according to the following settings :
1) TCC controller for single compressor ,
without the secondary card for compressors 3
and 4 :
Attention :
if dipswitches are not set
according to the above configurations i.e.
according to the number of compressors
effectively on line, the TCC controller card
may behave in unpredictable manner :
- the initialisation
ed - card remains locked on start-up.
- HP/BP alarms for non--existing com-
pressors.
7. PRACTICAL INSTALLA-
TION GUIDE
1) Sea-water cooling :
Install the pump/strainer assembly in such
a manner that a natural gentle upwards
slope exists from the sea-cock to the pump
itself. See also drawing hereabove ref. 6.1.
It is strongly recommended to install an
air-bleeder system both in the suction line
as well as immediately after the discharge
outlet of the pump. The advice is especial-
ly valid for pumps WEBAS-
TO250/350/1000. The WEBAS-
TO1500/2000 and Calpeda pumps 0.5HP
to 1 HP generally will not require a bleed-
er system to ensure proper operation.
For ALL boats it is strongly recommend-
ed to install a water-scoop at the entry of
the sea-cock and directed towards the bow
of the boat so that at speed positive pres-
sure builds up in the supply line to the sea-
water pump.
2) Sea-water cooling exits :
Provide for a separate sea-water exit for
each air-conditioning unit installed even if
only one pump provides cooling for all
units.
