Detailed Product Description

Temperature Controller

Product:7 x 3.5 x 7.5cm
Bore Size:70 x29mm
Main Function:
Refrigeration Controlling (Refrigeration / heat): temperature showing, temperature controlling (refrigeration/heat mode can be set), compressor start delay protection, temperature sensor error alarm, it can run periodically with the on-off rate and stop which has been set when the temperature sensor is broken.
Fan Controlling: 7 fan running modes: fan ahead or delay start, delay stop, temperature controlling start and stop, time controlling start and stop, always on, always off, run or stop when defrosting.
Defrost Controlling: 2 defrost modes (electric heat, hot gas), 3 defrost start mode (time alternation, accumulative compressor running time, real time clock), 2 defrost end mode (timing, controlled by both temperature and time), dripping, manual defrost, defrost sensor error alarm, high temperature alarm is forbidden when defrosting.
External alarm: one external alarm input, it can be set to 5 modes: always open, always open locked, always closed, always closed locked or forbidden.
High and Low temperature alarm: You can set the high and low temperature alarm point and alarm delay time, and can set high temperature alarm delay enable after defrosting.
Real Time Clock (RTC): Internal RTC, it is still running when power off, and it supplies an accurate time, used for real time defrost.
