Temperature Controller

Temperature  Controller

Main Function

Temperature display, temperature controlling(refrigeration/heat mode),compressor start delay protection, it can run periodically with the on-off rate when the temperature sensor is broken. 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, 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), high and low temperature alarm, sensor error alarm, one external alarm input, password, real time clock, C/F unit change.

Operating Guide

1, Meaning of the index lights on the panel

2,Meaning of the LED display

    The LED usually shows temperature, if it shows “SHr”, it means the temperature sensor is short, and “OPE” means the temperature sensor is open. The temperature and the alarm code (Axx) will show alternately when in the alarm state. The code is showing below:
