Series PCR-300/-310/-410/-300RC
ELECTRONIC COLD STORE CONTROLS
PRODUCT DATA
Features
• User friendly programming
• Compressor control with delayed start-up
• Evaporator fan control; fan in combination with
compressor, operating continuously or switched via
the evaporator temperature.
• Defrost control for electrical heating or hot-gas
defrosting; initiated via programmable time intervals,
at PCR-300RC by real-time clock
• Alarm output (not for PCR-310)

Specification (1)
Application
PCR-300, PCR-310, PCR-410 and PCR-300RC are
microprocessor-controlled cold store controls for refrigeration
and deep freeze systems.
The control switch the compressor, evaporator fan and the
defrost heating depending on the cold store temperature and
the adjusted parameters.
