Honeywell RTH2310B Manual

Your new Honeywell RTH2310B thermostat has been designed to give you many years of reliable service and easy-to-use, push-button climate control.Early Start allows the thermostat to “learn” how long your furnace or air conditioner takes to reach the set temperature.Simply program the desired times and desired temperatures into the schedule.The Honeywell RTH2310B thermostat will determine when to activate heating or cooling so that the desired temperature is attained at the desired time.

Your Honeywell RTH2310B thermostat has a feature that helps prevent damage to the compressor of your air conditioning.Because damage can occur if the compressor is restarted too soon after shutdown, this feature forces the compressor to wait 5 minutes before restarting.During the wait time, flashes on the screen. When the safe wait time has elapsed, the icon stops flashing and the compressor turns on.

Install two fresh AA batteries when the low-battery icon flashes on the screen.The icon will flash for 120 days, then the thermostat will cut power to the heating/cooling unit.The icon disappears once the batteries are replaced.Replace batteries once a year or before leaving home for more than a month.After replacing the batteries, set the time and the day (see page 7).The other settings are not erased when the thermostat is without power.
