ALARM CODES
SPECIFICATION
Front panel 34.5 (H) x 76mm (W) +/- 2mm
Cut out 30 (H) x 72mm (W) +/- 1mm
Operating temperature -5 to 55°C
Storage temperature -10 to 65°C
Power supply 12/24 Volt DC
Power consumption < 10 watts
Temperature range -40 to 90°C
Inputs = 2 NTC sensors 1.5m
Outputs:
Compressor output 17/7Amp
Fan output 10 Amp
Defrost output 10 Amp
Alarm output = built in buzzer
Problem solver
Remove power from controller
E1 or E2 check probe connections, clean plug in terminals
Probes can be extended to 100m but should have good
watertight connections, recalibration may be required for long
extension
LA alarm = excessive temperature, allow controller to cool
down and relocate or ventilate to keep cool
Relay failure = check full load amperage of output to ensure
that it is below ratings on controller
Defrost will not start = check coil temperature
Fan will not start = check coil temperature
Wiring
Warranty procedure
1 year replacement warranty
