Operating Instructions
Your InoKraft garage heater offers versatile control options and heating modes.
Control Options:
- Panel Touch Control: Directly operate the heater using the buttons on the unit's control panel.
- Remote Control: Use the infrared remote for convenient operation from a distance. Ensure AAA batteries are installed.
- Sensor Control: The built-in digital thermostat allows for precise temperature management.
Heating Modes:
- High Mode (H): Provides maximum power for rapid heating to reach the set temperature.
- Low Mode (L): Uses reduced power to maintain the set temperature, suitable for smaller spaces or less intense heating needs.
- ECO Mode (E): Automatically adjusts heating output based on ambient temperature to optimize energy consumption without sacrificing comfort. The heater will cycle between high and low power as needed and may shut off when the desired temperature is reached, reactivating when the temperature drops.
- Fan Only Mode (FAN): Circulates air without engaging the heating elements, useful for ventilation.
To switch between modes, press the Mode Selection button on the control panel or remote.
Temperature Control:
The built-in digital thermostat allows you to set the desired temperature between 40°F and 99°F. Use the Up/Down buttons on the control panel or remote to adjust the temperature. The heater will operate until the set temperature is reached, then cycle on and off to maintain it.
Timer Function:
Set a 1-24 hour timer for worry-free operation. The heater will automatically shut off after the set time has elapsed.
External Thermostat Option:
The heater supports two thermostat control options: built-in thermostat or external thermostat. A selector switch on the unit allows you to choose between these options. If using an external thermostat, ensure the switch is set to the appropriate position.
Maintenance
Regular maintenance ensures optimal performance and longevity of your heater.
- Cleaning: Disconnect power before cleaning. Use a soft, damp cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
- Fan Delay Function: The automatic fan delay function ensures effective heat distribution and helps cool down internal components after heating stops, contributing to a longer service life.
- Storage: If storing the heater for an extended period, ensure it is clean, dry, and stored in a safe, protected location.
Troubleshooting
If you encounter issues with your heater, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not turn on. | No power, tripped circuit breaker, incorrect thermostat setting. | Check power connection and circuit breaker. Ensure thermostat is set above ambient temperature. |
| Heater has power but won't adjust settings. | Thermostat selector switch is in the wrong position (external thermostat selected). | Set the switch to position 'I' for built-in thermostat control. Refer to the installation video for switch location. |
| Heater is not producing enough heat. | Incorrect mode selected, room size exceeds coverage, poor insulation. | Select High mode. Ensure room size is within 750 sq ft. Improve room insulation if necessary. |
| Heater shuts off unexpectedly. | Overheat protection activated, timer expired, desired temperature reached in ECO mode. | Check for obstructions around the heater. Reset timer if applicable. Heater may be operating normally in ECO mode. |
