AVT5589 A + - 4-channel thermostat with alarm. 4-channel thermostat with alarm

Description

The system is used to maintain and monitor temperature in four points. Thanks to the fact that the temperature of switching on and off the relays is set independently, virtually unlimited application possibilities have been achieved. The thermostat can work in both heating and cooling modes with almost any hysteresis loop width. In addition, the user has the option of setting the alarm temperature separately for each sensor, the exceeding of which will be signaled by a buzzer.

To make the thermostat's functionality even more attractive, the user can assign an individual name for each of the four measurement points.
