The Duo-Therm 5-button thermostat offers enhanced climate control features for RV environments. The intuitive LCD provides clear information, including current temperature, set temperature, operation mode, fan speed, and zone identification.

The thermostat's fan speed settings (Low, Medium, High, Auto) allow for customized airflow control. Additionally, the thermostat supports multi-zone functionality, enabling independent temperature control in different areas of the RV. Advanced features such as a compressor time delay and automatic restart after power interruptions add to its efficiency and convenience.
