The thermostat controls an electric heater. It works like most programmable thermostats — you set a target temperature and it turns the heat on or off to reach it.
Finding the buttons
To access all the buttons, you need to open the two side panels — they swing out like little doors on the left and right of the thermostat. The left panel has the programming buttons (Day, Hour, Min, etc.) and the right panel has the preset and temperature buttons.
The Basics
The display normally shows the current room temperature. To see the target (setpoint) temperature, briefly press the ▲ or ▼ button — it appears for 5 seconds.
The little flame icon shows heating is actively running. More flames = more heat output.
There is a physical On/Off switch on the thermostat. This completely cuts power to the heater.
- On — normal operation (heating controlled by thermostat)
- Off — heater is completely off (won't affect your stored schedule or clock)
When to turn it off
Use Off in summer or during a long absence when you want zero heat.
Day-to-Day Use
The simplest way to adjust temperature is just pressing ▲ or ▼ until you see the temperature you want.
If you are running a schedule (Automatic mode), this creates a temporary override. The schedule resumes at the next programmed period.
There are three shortcut buttons on the thermostat for common situations:
Comfort
For when you're home and awake. Default: 70°F
Economy
For when you're asleep or away. Default: 62°F
Vacation
For extended absences (days or weeks). Default: 50°F
Press the button once to jump to that preset. The icon appears on screen.
Customizing a preset
To change a preset's temperature: press ▲ or ▼ to your desired temp, then press-and-hold the preset button until its icon appears.
Two Modes: Automatic vs. Manual
Automatic (Auto)
Follows the programmed schedule. Switches between Comfort and Economy temps on a set timetable. The 'A' icon appears on screen.
Manual
Ignores the schedule and holds whatever temperature you set — indefinitely, until you change it.
Press the Mode/Ret button to toggle between modes.
Recommended setting
Automatic mode is recommended — it saves energy by automatically lowering the temp when it's not needed.
Temporary Override
You can temporarily change the temperature without affecting the whole schedule:
- Press ▲ or ▼ to set your desired temperature.
- The thermostat holds that temperature until the next scheduled period kicks in.
- At that point, it automatically goes back to following the schedule.
Error Messages
Temperature is below sensor range. Heat is ON. Usually not a concern.
Temperature is above sensor range. Heat is OFF. Usually not a concern.
Wiring or sensor issue. Contact the property owner.
After a Power Outage
Most settings (schedule, presets) are saved through a power failure. However, if power is out for more than 6 hours, the clock and Daylight Saving Time setting will need to be reset:
- Press Hour, then Min to reset the time.
- Press Day to reset the current day.
- The thermostat will return to whatever mode it was in before the outage.
