1. the main features
▲ with large digital numbers display, so that the working status of thermostats and display
of measured values more intuitive.
▲ adjusted using the I2C and storage technology, data protection save power.
▲ external three-phase fan with fan motivation (regular start and stop) function.
▲ with over temperature alarm, over temperature trip, fan start and stop functions.
▲ with 4-20mA analog current output and RS-485 communication.
