How to use

Install the thermostat on a suitable wall box following local electrical codes and wiring guidelines. Connect the thermostat in series with the heating actuator or load according to the installation diagram provided by the system manufacturer. Rotate the knob to select the desired temperature setpoint; the internal mechanism will switch the connected heating circuit when the ambient temperature crosses the setpoint. No programming is required; adjustment is immediate and mechanical.

Recommendations

Mount the thermostat away from direct sunlight, drafts, or heat sources to ensure accurate temperature sensing. Verify that the connected load and wiring meet the devices voltage and frequency ratings. For installations in larger or zoned systems, use this thermostat to control individual rooms or zones and combine with centralized control where precise scheduling or remote control is needed.
