- Frequency: 50/60 Hz
- Input power rating: 1000 W at 115 V (+15 % / - 20 %)
- Airflow requirement: Minimum 3 m/s
- Operating temperature: -14 °F to 109 °F (-25 °C to 43 °C)
- Storage temperature: -4 °F to 158 °F (-20 °C to 70 °C)
- Humidity: < 90 % rH non-condensing
Service and safety
R290 Refrigerant: When performing service or repairs on systems using R290, exercise extreme caution. R290 is a flammable refrigerant. Ensure proper handling procedures are followed to prevent leaks or ignition hazards. Always use appropriate tools and follow safety protocols for flammable refrigerants.

Practical help
Common problems
Check that the airflow is at least 3 m/s. Ensure the controller is not overheating.
Verify all wiring against the color-coded pinout diagram provided in the manual.
Before use
- Verify supply voltage is 115V (+15%/-20%).
- Ensure the installation environment provides at least 3 m/s airflow.
- Check that all sensor and relay connections match the color-coded diagram.
- Confirm operating temperature is within -14 °F to 109 °F.
- Ensure humidity is below 90% and non-condensing.
