tst digital temperature switches compressor defroster fans

Regulate a compressor, defroster and fan in refrigeration systems using the Series TST Digital Temperature Switch. This switch features dual probe input, three SPST relays, alarm output, and digital input. The digital input can be configured to control fan and compressor activity or defrost synchronization.

The Series TST offers 48 programmable parameters to optimize system performance. Parameters are password protected for security. The user can define set point, regulation times, fan operation, alarms, compression cycling, drip time, and many more. The unit offers short cycling protection to avoid hard starts, overload voltages, and unnecessary equipment wear.

Dual probe input permits defrost termination by temperature. The ambient and defrosting probe temperature can be viewed on the 3-digit display. Relay, fan or defrost status is indicated by LEDs on the front of the switch. The Series TST includes two probes, mounting clip, gasket, rear terminal cover, and instruction manual
