Programmable controller

HMI VOLT BMS

The HMI VOLT programmable controller is used to control the operation of fans and electric heating elements in installations with electric unit heaters. The device automatically regulates the system's operation by comparing the room temperature with the set temperature, ensuring thermal comfort and energy savings. It allows operation in heating, cooling or ventilation mode. It features a large backlit LCD screen, touch buttons, and the ability to programme a weekly schedule (6 time slots per day). The controller works with a temperature sensor (internal or external – included) and supports RS485 communication with the Modbus RTU protocol, enabling integration with a BMS.
