SKOPE CAREL ir33 Controller
Service Manual
Temperature Probes
Three temperature probes feed data to the electronic controller - the control,
ambient and evaporator probes. Refer to page 73 for information on
servicing the probes.
Control Probe
The control probe controls the freezertemperature and provides the freezer
temperature for the electronic controller to display.
Ambient Probe
The ambient probe measures the temperature around the refrigeration unit
and activates the high ambient (
HO
) alarm if the temperature exceeds 40°C
(freezers) or 32°C (ice storage cabinets). Instances of high ambient alarm
activation are recorded and can be reviewed by accessing the parameters
and reviewing the AHO parameters (see page 20).
Evaporator
Probe
The evaporator probe measures the evaporator coil temperature. The
evaporator coil temperature is used for evaporator fan operation (fan will
start when evaporator coil temperature drops to -8°C) and to stop the defrost
cycle (defrost cycle stops when evaporator temperature raises to +4.5°C).
Temperature
Probe Reading
The temperature of each of the three temperature probes can be displayed
by pressing and holding both the
and
keys simultaneously for 5
seconds.
To display the temperature probe readings
Temperature probe readings
1. Press and hold both
the
and
keys simultaneously
for 5 seconds.
2. Press and hold the
key to scroll the
probes (see table below). The
key
is not active for this function. This
function will time out after 60 seconds
(cannot be turned off prior to 60
seconds elapsed time).
