BJ-S Digital Thermostat

BJ-S Digital Thermostat

BJ-S Digital Thermostat is a digital temperature protection relay that can replace the traditional bimetallic control switch, designed to automatically control the install enclosure inside temperature & humidity variation within a specific range. This temperature protection relay can be used in the worst environment for long-term use because of its reliable design. This thermostat relay is the ideal product to protect the normal efficient operation of electric equipment and to reduce cost.

It is with LED / LCD display and an optional RS485 communication port for remote monitoring. Optional customized control logic design can be used in other places that need temperature and humidity control.
