Emerson White Rodgers NP110 Operating features
Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.
- SIMULTANEOUS HEATING/COOLING SETPOINT STORAGE — You can enter both your heating and cooling setpoints at the same time. There is no need to re-enter the thermostat at the beginning of each season.
- TEMPERATURE SETTING — Press UP or Down Button until the display shows the temperature you want.
The thermostat will keep the room temperature at the selected temperature.
- °F/°C CONVERTIBILITY — The factory default setting is Fahrenheit. Clipping W904 jumper on the circuit board will alter this feature to Celsius temperature setting. See diagram on page 11.
- LOW BATTERY INDICATOR — If the 2 “AAA” alkaline batteries are low and should be replaced, the display will be blank except for Battery Indicator. When the batteries are low, pressing any button will cause the display to operate for ten seconds. After ten seconds, the display will be blank except for Battery Indicator . After Battery Indicator has been displayed for 4 weeks, the thermostat will raise the temperature 10° above your setpoint in COOL mode and drop the temperature 10° below your setpoint in HEAT mode. You cannot program with low batteries, but you can override setpoint temperature.

Emerson White Rodgers NP110 TROUBLESHOOTING
Reset Operation
If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation you can reset the thermostat by pressing UP and Down Button at the same time while moving the SYSTEM switch from OFF to HEAT. This also resets the factory defaults. If the thermostat has power, has been reset and still does not function correctly contact your heating/cooling service person or place of purchase.
Batteries
For best results, replace batteries once a year with new premium brand alkaline batteries such as Duracell® or Energizer®.
