The Honeywell RTH111B1016/A Digital Non-Programmable Thermostat is designed to provide you with the most basic push-button climate control while offering the reliability to give you many years of service. The thermostat is non-programmable, so in simplest you us the Up/Down arrow buttons to set the temperature you want (setpoint), select ‘Heat’ or ‘Cool’, and select the fan to ‘Auto’* or ‘On’ – that’s it! The digital LCD display shows the ambient (measured) temperature at all times. You also have one-touch access to view the setpoint temperature at any time by pressing the Up or Down arrow. When the Cooling system is on, ‘Cool On’ text is displayed on the LCD display, and when the heating system is on ‘Heat On’ is displayed. There is a battery backup, two AAA batteries required (sold separately), that will maintain your setpoint even if you lose power; a low battery indicator displays when the batteries need to be replaced. A built-in compressor protection feature helps prevent damage to the compressor in your air conditioning or heat pump system which can occur if the compressor is restarted too soon after shutdown.
This thermostat is compatible with the following systems:
- Gas, Oil or electric furnace
- Central air conditioner
- Hot water system with or without pump
- Millivolt system
- Central heating and cooling system
- Heat pump without auxiliary/backup heat
* In ‘Auto’ mode (the most commonly used setting), the fan runs only when the heating or cooling system is on.
Please Note: This thermostat does not work with heat pump systems and electric baseboard heat (120v-240V)
