This is a room thermostat suitable for every kind of building where reduced energy consumption and high comfort need to be met. The ability to switch between control modes depending on occupancy makes it particularly suitable for public spaces, such as hotel rooms, offices, schools, and hospitals, etc.
Function
The room thermostat regulates the heating and/or cooling in a room via on/off outputs for 2- or 4-pipe installations and has a function for three-speed fan control. The large LCD touch display shows the status and is also used to access all parameters, such as setpoint, hysteresis, fan speed etc. The unit has a built-in temperature sensor for controlling the room temperature. The change-over function can be controlled using an external PT1000 sensor or via a digital input connected to any potential free contact. Functions such as mold protection and automatic valve exercise ensure proper functionality and a problem-free installation over time.
The modular design makes it easy to install and the flush mounting gives the unit a discreet appearance. The unit can operate in standalone mode or through Modbus,
