Electronic Controller Operations
Introduction
The SC112N-A chiller is fitted with a CAREL S4 electronic controller. The
electronic controller is visible on the front panel and is housed inside the
controller box at the front of the refrigeration system.
The electronic controller controls and displays the chiller temperature and
signals temperature alarms. It uses two temperature probes within the
refrigeration system to collect data and runs the chiller accordingly.
The electronic controller is pre-programmed; SKOPE does not recommend
that the settings be changed unless it is absolutely necessary. To ensure
efficient operation, the electronic controller automatically forces a defrost
cycle when required.
Faceplate
Because the electronic controller plays such an important role, it’s helpful to
know the parts of the faceplate you may use.
IMPORTANT
The electronic controller must only be adjusted by an authorised
service agent.
