How to use

Install the controller on an interior wall at a representative height for ambient measurement, away from direct sunlight, drafts and heat sources. Use the display to read the current room temperature and adjust the setpoint according to comfort requirements. After commissioning and connection to the heating or cooling controller, operate the device to change setpoints locally; the controller transmits the setpoint to the connected regulation system for automatic modulation of the HVAC equipment.

Recommendations

For stable temperature control, place the unit on an interior wall in a central location of the room and avoid mounting near windows, doors, radiators or supply vents. Calibrate setpoints according to occupancy patterns and allow a settling period after changes to confirm comfort and system response.
