Theword HOLD will appear in the display. Press the HOLD/ENDbutton a second time and the thermostat will return the temperaturesettings to the programmed comfort schedule.

Pressing the UP orDOWN button again will temporarily change the setpoint asneeded. At the next programmed time, the programmed comfortschedule will resume.CHANGING BATTERIESIn some situations, two AA batteries are the power source for thethermostat. If batteries are used with your equipment then theyshould last about one year. As the batteries lose their power abattery icon appears on the display. As the batteries get weaker, theicon goes down to one black bar and then none. As the iconbecomes empty, you will begin to lose thermostat functionsbecause the batteries are losing their power. When the batteries arecompletely dead, you won’t be able to use the thermostat.When using batteries for power, we recommend you replace themwith two AA alkaline batteries. They are in a compartment underthe lid on top of the thermostat. You do not have to remove thethermostat from the wall to replace the batteries. Simply open thelid, lift out the batteries, and replace them like you would any otherbattery operated device.TROUBLESHOOTINGWhat if AUX HEAT appears on the display?(Heat pump model only)If auxiliary heat is on, you will see AUX HEAT indicator in thedisplay. When it is on this means the system has determined thatit’s too cold outside for your heat pump to heat the house withouthelp, so it’s getting help from the electric heaters. This happensautomatically.NOTE: This indicator does not mean there is a problem with yoursystem.What if E--Heat appears on the display?If the heat pump is not working properly, you can manually turnon the emergency heat for extra help in heating. You’ll knowthere’s a problem if the house can’t seem to get warm when it’scold outside.You want to avoid using emergency heat, though, because it’s themost expensive option. And, of course, if you suspect a problemwith your heat pump, call your heating and cooling dealerimmediately.Table 1 – Programming TableENERGY STARFACTORY DEFAULT VALUES NEW COMFORT SCHEDULEPERIOD TIME COOL HEAT MoTuWe ThFrTIME COOL HEAT SaSuTIME COOL HEATMORNING 6:00A.M.78_F26_C68_F20_C 1) 2) 3) 13) 14) 15)DAY 8:00A.M.85_F29_C60_F16_C 4) 5) 6) 16) 17) 18)EVE 5:00P.M.78_F26_C68_F20_C 7) 8) 9) 19) 20) 21)NIGHT 10:00P.M.82_F28_C60_F16_C 10) 11) 12) 22) 23) 24)TB -- PAC / TB -- PHP
