Overview
The chiller may be fitted with refrigeration unit UB84AMD (with Carel ir33
electronic controller) or UB84ANF (with Carel S4 Evo electronic controller).
Refer to the unit rating label on the front of the unit to determine the
refrigeration unit model, or the electronic controller faceplate to determine
the electronic controller type.
The electronic controller controls and displays the cabinet temperature. The
preset temperature setting controls the internal air temperature, and signals
temperature alarms.
The electronic controller is located behind the front panel and is connected
to the refrigeration unit junction box.
Customised SKOPE controllers cannot be replaced with standard CAREL
controllers.

Cycles Defrost Cycle
To ensure efficient operation, the electronic controller forces a defrost cycle
when required. During a defrost cycle, the compressor stops, DEF and the
will display on the electronic controller faceplate. The chiller will resume
normal operation once the defrost cycle has finished. A manual defrost can
also be initiated by pressing and holding the button.
The standard minimum defrost interval is 2 hours (parameter ‘dl’). In addition
to this the controller can initiate a demand defrost; if the evaporator coil is
colder than parameter ‘d11’ (-9°C) for longer than parameter ‘d10’ (10
minutes) a demand defrost will be initiated.
Frequent demand defrosts are likely in high load situations or where
evaporator refrigeration faults exist.
Continuous Cycle
The continuous cycle can be used to pull down the temperature of product
inside the chiller quickly. During a continuous pull down the compressor runs
continuously for a set time.
To start a continuous cycle
To stop a continuous cycle
Temperature
Probes Three temperature probes feed data to the electronic controller - the control,
evaporator and condenser probes. Refer to page 55 for information on
servicing the probes.
Control Probe
The control probe controls the chiller temperature and provides the chiller
temperature for the electronic controller to display.
Condenser Probe
The condenser probe measures the condenser coil temperature and
triggers the condenser over-temperature alarm (Cht).
1. While the chiller is switched on and
running, press and hold the and
buttons for five seconds.
The symbol will display during a
continuous cycle.
1. The electronic controller will
automatically stop the continuous cycle
after a period of time.
The continuous cycle can be stopped
by pressing and holding the and
buttons for five seconds.

Condenser over-temperature two stage alarm
To prevent damage to the refrigeration system, during periods of excess
condensing temperature, the electronic controller will completely shutdown
the chiller (and can only be reset by replugging the chiller into the power
supply).
This is a two stage alarm - Stage One is simply a warning code of ‘cht’,
which ideally the customer should respond to. Cleaning the condenser may
possibly remedy the problem. If the condenser fan fails, the controller will
quickly move to Stage Two alarm ‘CHt’ and completely shutdown the chiller.
• Parameter ‘Ac’ (SKOPE default) = 60 (Shutdown = 60°C)
• Parameter ‘AE’ (SKOPE default) = 10 (Warning Initiation = Ac minus
AE/2 = 55°C. Warning Reset = Ac minus AE = 50°C).
Note: In low ambient conditions the alarm may not activate due to a blocked
condenser. In applications with a continuously low ambient, it may be
worthwhile lowering the alarm threshold if condenser blockage notification
is wanted.
Hardware
Setup Refer to the refrigeration unit wiring diagram. The controller has five
separate inputs, three of which are used for temperature probes.

Programming Set-Point
The cabinet is manufactured with a pre-set control temperature set-point. If
this set-point does not match your required storage temperature it is
recommended that you change the set-point accordingly. The set-point can
be adjusted between a temperature range as detailed in the parameter sets
beginning on page 17.
To view and adjust the temperature set-point
1. To view the set-point: press and hold
the key for 2 seconds, until the
set-point value flashes
2. To adjust the set-point: press either the
and keys to display the
required set-point value.
3. Press the key again to memorise
the new set-point value. If this is not
done within 60 seconds, changes will
be lost and you will need to repeat the
above procedure.

Controller Reset
To delete program modifications and reset the controller to SKOPE default
program, or when a replacement controller is being fitted, a ‘Controller
Reset’ must be performed.
To reset the controller
1. Disconnect the chiller from the power supply.
2. Press and hold the key while
plugging the chiller into the power
supply (this may require two people).
After a few seconds the controller is
reset and program mode ‘bn0’ is
displayed. The controller must never be
left in program mode ‘bn0’ as failure
will occur.
3. Press the or keys to select the
appropriate bn program (see page 17).
4. Immediately press the key to
confirm the preferred program. If not
confirmed within 60 seconds the chiller
will remain in program mode ‘bn0’ (and
cause failure). If this occurs, repeat the
above procedure.

to access parameters. Also used for programming.
4Light (down): Button. Press to switch the cabinet light on
and off. Also used for programming.
