Electronic Controller
Introduction
The electronic controller is visible through a cut-out in the front panel. It uses
temperature probes and a door switch to collect data and runs the chiller
accordingly. The electronic controller can be manually switched between
‘Normal’ and ‘Energy Saving’ operating modes. Additionally, the controller
can be programmed to automatically switch the chiller between ‘Normal’ and
‘Energy Saving’ modes depending on chiller usage (see page 8 for more
information).
To ensure efficient operation, the electronic controller forces a defrost cycle
when required.
Door Switch
The front door (electronic controller side) is fitted with a door switch which
tells the electronic controller when the door is opened and closed. If the door
is opened for an extended period an alarm will sound. Press the alarm
button on the electronic controller to mute the alarm (see below).
Faceplate
Because the electronic controller plays such an important role, it’s helpful to
know the parts of the faceplate you may use.
