Setup
Initial Power On
After installation, ensure all electrical and plumbing connections are secure and checked by a professional. Turn on the main water supply to the unit, allowing it to fill completely. Then, activate the electrical breakers for the water heater.
Temperature Setting
The unit features an integrated LED display for temperature control. Use the '+' and '-' buttons on the unit to adjust the desired water temperature. The adjustable range is typically from 86°F to 140°F.
WiFi Connection
The WN36 model supports remote control via WiFi. Refer to the included "WiFi Connection Instructions" for detailed steps on connecting your device to the WINTEMP app. This feature allows for convenient remote temperature adjustment and monitoring.
Operating Instructions
The WINTEMP tankless electric water heater is designed for efficient, on-demand hot water supply.
- Automatic Operation: The unit automatically activates when water flow is detected (e.g., opening a hot water faucet) and deactivates when flow stops. This ensures hot water is produced only when needed, eliminating standby energy loss.
- Stable Temperature: The self-regulating technology continuously adjusts energy consumption based on incoming water temperature and flow rate. This maintains a consistently stable output water temperature, preventing uncomfortable fluctuations during use.
- Energy Efficiency: The system reduces power usage when water flow decreases and consumes no energy when idle. This design achieves up to 99% energy efficiency, suitable for 3-5 usage points in a home.

Maintenance
Regular maintenance ensures the longevity and efficient operation of your water heater.
- Regular Inspection: Periodically check for any signs of leaks, corrosion, or damage to the unit and its connections. Address any issues promptly.
- Inlet Filter Screen: The cold water inlet is equipped with a filter screen to prevent debris from entering the unit. Inspect and clean this filter periodically (e.g., every 6-12 months) to ensure optimal water flow and prevent sediment buildup. Turn off water and power before cleaning.
- Descaling: In areas with hard water, mineral buildup (scale) can affect efficiency over time. Descaling may be necessary. Consult a qualified plumber for professional descaling procedures.
- No Tank Maintenance: Unlike traditional tank heaters, this tankless unit does not store water, thus eliminating the need for flushing for sediment or mineral scale accumulation within a tank.
Troubleshooting
If you encounter issues with your WINTEMP water heater, refer to the following table for common problems and solutions. For problems not listed or if the suggested solutions do not resolve the issue, please contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | No power to unit, water supply off, insufficient water flow rate to activate heater | Check electrical breakers, ensure water supply is fully open, verify minimum flow rate requirement is met (0.75 GPM to activate). |
| Inconsistent or fluctuating temperature | Fluctuating incoming water pressure, sediment in inlet filter, multiple hot water demands exceeding unit capacity | Check household water pressure, clean inlet filter screen, reduce simultaneous hot water usage. Ensure installation meets electrical specifications for optimal performance. |
| Error code on display | Internal fault, overheat protection activated, sensor malfunction | Note the error code and refer to the full instruction manual for specific code meanings. If not found, power cycle the unit (turn off/on breakers). If issue persists, contact customer support. |
| WiFi connection issues | Incorrect WiFi password, router issues, unit too far from router, app malfunction | Re-enter WiFi password carefully, restart your home router, ensure the unit is within effective WiFi range, reinstall the WINTEMP app if necessary. |
Note: A customer-submitted video (below) demonstrates instances of temperature fluctuations and the unit reaching high temperatures (165°F) before erroring out, despite being set lower. While the product's maximum set temperature is 140°F, if you experience temperatures exceeding this or unexpected fluctuations, ensure your installation meets all electrical and plumbing specifications and contact support if issues persist.
