Timers
There are several timers which influence the thermostat’s operation: If any of
the timers listed below is preventing the equipment from turning on, the
display icons which show the equipment is operating will be flashing to
indicate a turn-on delay is present.
Five-Minute Compressor Timeguard
This timer prevents the compressor from starting unless it has been off for 5
minutes.
Minimum On Timer
Once the equipment has been turned on, it must remain on for 3 minutes. A
change in mode or setpoint will cancel this timer.
Cycle Timer
Based on the selection of 2, 4, or 6 cycles per hour, this timer is set to 30, 15,
or 10 minutes. This much time must elapse from the start of one cycle before
another cycle can start. It serves to impose the cycles per hour limits.
Auto Changeover Timer
To prevent unnecessary cycling between heating and cooling modes, this
timer prevents a changeover to the opposite mode until a demand exists in
the opposite mode for 20 minutes. It is defeated when setpoints are changed
so that the opposite mode is immediately available if desired.
