6. Operating Instructions
6.1 Touchscreen Interface
The thermostat features a large LCD touchscreen for direct control. The main screen displays the current temperature, set temperature, operating mode, and Wi-Fi status. Use the up/down arrows to adjust the set temperature. The power icon turns the heating system on or off. The hand icon activates a temporary hold.
6.2 Programming Schedules
The K902-W allows for programmable schedules with 4 or 6 time periods per day. This feature helps optimize energy usage by adjusting temperatures automatically based on your daily routine. Schedules can be set directly on the thermostat or more conveniently through the Hoot app.
- Access the 'Schedule' or 'Program' menu on the thermostat or within the Hoot app.
- Define desired temperatures for each time period (e.g., Wake, Away, Home, Sleep).
- Apply the schedule to specific days of the week or all days.
6.3 Temperature Control
You can manually adjust the temperature at any time. This adjustment will typically override the current schedule until the next scheduled period begins. To maintain a specific temperature indefinitely, use the 'Hold' function. The thermostat also features a user-defined maximum temperature lock to prevent settings from exceeding a certain limit.
7. Maintenance
The KING K902-W thermostat requires minimal maintenance.
- Cleaning: Wipe the screen and casing with a soft, damp cloth. Do not use abrasive cleaners or solvents.
