During periods of low humidity (especially during cold weather), you may feel or see a spark discharge when you touch the ther- mostat. This may cause the program to be lost or the thermostat to display incorrectly. To correct this, remove the thermostat from the wall and disconnect the batteries. Wait about two minutes, then reconnect the bat- teries. The thermostat will revert to the fac- tory preset program until you reprogram the thermostat. If you don’t want to reprogram
