The recommended hole size for the GE-VCPL is 9  
5/32” x 3 5/8”but in addition there are the holes for  
the fasteners as per the drawing on the reverse of  
this instruction manual.  
DEFROST CYCLE  
*(ꢀ9&3/ꢁ  
It may be possible that from time to time the user  
wants to use some extra defrost cycle(s). To activate  
a manual defrost, push the manual defrost button and  
keep it pressed for a minimum of 5 sec. Until the  
defrost signal shows on the display.

DESCRIPTION  
PARAMETER LISTING  
Access through set button:  
The VCPL series is especially designed for  
use in the commercial refrigeration and is  
available in various different models. The  
VCPL is also available with communication  
properties.  
In addition to extremely accurate temperature  
control the VCPL offers the user diagnostics,  
marketing information and current statistics  
scroll i.e. average temperature, lowest  
temperature, highest temperature, number of  
door openings, compressor cycles and  
compressor running hours.  
As standard all models in the VCPL series are  
fitted with 6 relays switching : compressor,  
heating element or solenoid valve, external  
alarm, evaporator fan, on/off switch and  
light(s). All relays in this unit have a switching  
capacity of 16 Amp. @ 240 Volt.  
A manual defrost may be activated as many times as  
required.

WARNING  
This manual is part of the product and should be kept  
near the instrument for quick reference.  
The instrument should not be used for purposes other  
than described and/or specified by the manufacturer.  
These controls can only be used with GE double  
insulated sensors.

SAFETY PRECAUTIONS  
Ensure that the supply voltage is correct before  
connecting the instrument. (240 Volt )  
Ensure that the instrument is not exposed to water or  
any other liquid.  
Ensure that the current that is switched does not  
exceed the maximum switching capacity of the  
instrument. If the current to be switched is greater  
than the instrument limits, a separate relay should be  
installed.

CHANGING PARAMETER VALUES  
To change the parameter values switch the power to  
the unit off, push the temperature set button and keep  
it pushed whilst switching the power on again. The  
display will flash and intermittently show the figures  
888. Once the display stops flashing, the instrument  
is in parameter mode and the values can now be  
changed.  
To scroll through the parameters push the  
temperature set button and to change the value of the  
parameters use the ‘value’ buttons.  
When finished, release all buttons and wait until the  
display shows the actual temperature again.

WARNING  
To clean the facia of the GE-VCPL use wet soapy  
rag.  
The instrument is an electronic device, do not use  
water or any other cleaning liquid to clean the facia  
of the instrument as this may cause serious and  
unnecessary damage to the system and may be  
dangerous.

TO SET THE TEMPERATURE  
In case of an instrument failure or faulty functioning  
of the instrument, return it to your local distributor or  
direct to the manufacturer. If the unit is still in its  
warranty period it will be replaced free of charge.  
To set the temperature push the ‘temperature set  
button’ and the display will intermittently show the  
letters SP (set point) and the pre-set temperature. To  
increase the temperature use the value up button (),  
to decrease the temperature use the value down  
button (v).  
Once the required temperature is selected, release the  
buttons and wait until the display shows the actual  
temperature again. The instrument has now adopted  
the new setting and will operate in accordance with  
these new instructions.  
WIRING INSTRUCTIONS  
All wiring instructions are printed on the housing of  
the unit and contain all possible information needed  
to connect the GE-VCPL  
Follow these instructions and ensure that all  
connections in the terminals of the instrument are  
properly fastened as loose connections may influence  
the performance of the instrument and may cause  
sparking.  
The GE-VCPL is powered by 240 Volt and should be  
connected direct to the mains.  
IMPORTANT  
Only authorised and competent personnel should  
connect and/or disconnect the GE-VCPL.  
cURus Approval Pending  
GE Electronic Temperature Control Systems should not be  
exposed to low temperatures or high humidity, such as  
outdoor or refrigerated environments. It is the customer’s  
responsibility to determine the proper application of the  
controls and to specify the optional Conformal Coating if the  
controls are going to be used in these environments.
