White-Rodgers 1F83-277 Air Conditioning Auto Changeover Manual: Questions and Answers
What does flashing setpoint temperature mean on White-Rodgers 1F83-277 Air Conditioning Auto Changeover?
The thermostat is in compressor time delay mode to protect the compressor from short cycling. The setpoint flashes for about five minutes. User Manual, p. 10
Why is my White-Rodgers 1F83-277 Air Conditioning Auto Changeover cycling too fast or too slow?
Digital thermostats cycle faster than older models but use no extra energy. To increase cycle time, select SL for slow cycle in the menu. User Manual, p. 9
