To access the programmable parameters of
the TECC electronic controller proceed as
following :
Raise set-point temperature to the max. i.e.
29° Centigrade. Then turn off system by
pressing the
Press simultaneously the 2 set-point keys for
aprox. 3 seconds until you see to the left of
the digital display a single number code indi-
cating the programming line presently valid
and to the right a single ou double read-out
indicating the present programming value.
To go to the next programming line (left sin-
gle number), press
If you modify the programming value (to the
right of the display), you need to validate the
changes made by pressing the
go to the next programming line. This step
will validate and memorize the changes
made.
Here-after the explanations regarding the
available programmable functions :
1° Functions accessible by raising the set-
point to 29° C. :
Code <0> - factory setting : +4° Celsius -
lower set-point temperature of the chilled
water circuit when in cool cycle. This value
gives the compressor cut-out point when in
cool cycle.
Adjustment range : between 0°C and +15°C.
Code <1> - factory setting : +7° Celsius -
higher set-point temperature of the chilled
water circuit when in cool cycle. This value
gives the re-start point of the compressor(s)
after a thermostatic interruption (in cool
cycle).
Adjustment range : between 2°C and +18°C.
Code <2> - factory setting : 40° C. higher
set-point temperature of the chilled water cir-
cuit when in heat cycle. This value gives the
cut-out point of the compressor(s) when
functioning in heat cycle.
Set-point temperature adjustable between
30° and 55° C.
Code <3> -factory setting : 37° C. - lower
set-point temperature of the chiller water cir-
cuit when in heat cycle. This value gives the
re-start point of the compressor(s) after a
thermostatic interruption (in heat cycle).
Set-point temperature adjustable between
27° and 52° C.
Code <4> - pre-programmed value : 0 - cali-
bration of the chilled water circuit tempera-
ture - possible adjustment between -9° and
+9° C.
Code <5> - factory setting : 15 - time delay
in minutes before the digital display goes
into blank/sleep mode. Cycle LED flashes
discretely to indicate system is operational.
Code <6> - factory setting : 1 - first start up
delay in seconds after connecting AC supply.
Adjustable between 1 and 20 seconds.
Code <7> - factory setting : 0 - calibration
of room temperature read-out. Correction
between +9 and -9° C.
Code <8> - pre-programmed value : 0.
Factory calibration of AC voltage 50 Hz as
displayed on the digital panel when access-
ing the secondary commands - F/Blower key.
Correction between -20 and +20 Volt.
Code <9> - pre-programmed value : 0 -
Functioning principle of staging relay :
Value 0 : the relay functions as a staging
relay (see also page 25)
Value 1 : the relay functions as the outlet con-
trol for a soleniod valve system for the air-
handlers directly controlled by the main
TECC controller.
Value 2 : the relay functions as a witness for
a system halt and general alarm (A01, A02,
A09, etc) :
- contacts closed between C2 and R2 or con-
tacts open between C2 and T2 = no alarm
- contacts open between C2 and R2 or con-
tacts closed between C2 and T2 : general
alarm and system halt.
Value 3 : cycle indication
- contacts closed between C2 and T2 = heat
cycle
- contacts closed between C2 and R2 = cool
cycle
System Halt : contacts closed between C2
and R2.
Code - pre-programmed value : -10.
Factory calibration of AC voltage 60 Hz as
displayed on the digital panel when access-
ing the secondary commands - F/Blower key.
Correction between -30 and +20 Volt
Code - Program version
Re-intializing the factory default set-
tings :
It is possible to force the program to re-ini-
tialize all program values to factory default
settings by the following procedure :
When reading the line as above (through
the 29° set-point), push the
the program version starts to flash. Keep the

PROGRAMMING MODE :
To enter programming mode : raise or lower set-point to 29 or 15° C.
Turn off system by pressing
Press simultaneously keys <11>. The display will show to the left
<15>, the number code of the current programming line and to the right
<16> the present value.
To validate and memorize modified parameters press the
