3.3 Electrical Wiring
Connect the heater to a dedicated 240V hardwired circuit. Refer to the wiring diagram provided in the packaging for specific connection details. Ensure all connections are secure and insulated.
4. Operating Instructions
The heater can be operated using the digital touch panel on the unit or the included remote control.
4.1 Powering On/Off
- Press the Power button on the control panel or remote to turn the heater on or off.
4.2 Heat Settings
The heater offers three heat settings:
- H (High): 10000W output for maximum heating.
- L (Low): 7500W output for moderate heating.
- FA (Fan Only): Operates the fan without heat, useful for air circulation.
Use the Heater Control button on the panel or remote to cycle through these settings.
4.3 Digital Thermostat
Set your desired temperature using the Temperature Control buttons on the panel or remote. The heater will automatically maintain the set temperature.
4.4 ECO Function
The ECO function helps save energy by automatically adjusting the heater's operating mode based on the current temperature relative to the set temperature.
- When the current temperature is within 5°F below the set temperature, the heater will switch to low gear.
- When the current temperature is 1°F above the set temperature, the heater will stop heating, and the fan will stop after 60 seconds.

- Inspection: Annually inspect the heater for any signs of damage, loose connections, or wear. If any issues are found, contact a qualified technician for repair.
6. Troubleshooting
This section addresses common issues you might encounter with your heater.
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not turn on. | No power supply; circuit breaker tripped; overheating protection activated. | Check power connections and circuit breaker. Allow heater to cool down if overheating protection was activated. |
| Fan does not work or rotates slowly. | Input voltage is lower than 208V. | Check the Voltage Display Screen on the unit. If voltage is below 208V, consult a professional electrician to rectify the power supply issue. |
| Heater produces insufficient heat. | Incorrect heat setting; thermostat set too low; room size too large for heater capacity. | Ensure heater is on 'H' (High) setting. Adjust thermostat to a higher temperature. Verify heater capacity is appropriate for the space. |
| Heater cycles on and off frequently. | Thermostat setting too close to ambient temperature; ECO function active. | Adjust thermostat to a more stable temperature. This behavior can be normal if the ECO function is enabled and maintaining a precise temperature. |
