OPERATIONAL INFORMATION
Timers
Five
−
Minute Compressor Timeguard
This timer prevents compressor from starting unless it has been off for at least 5
minutes. It can be overridden for 1 cycle by simultaneously pressing FAN and
UP buttons.
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. It can be
defeated for one cycle by simultaneously pressing the FAN and UP buttons.

−
Minute Staging Timer
In multistage heating or cooling, this timer prevents any higher stage from
turning on until preceding stage has been on for 10 minutes. When staging
between compressor and electric heat or between compressor and furnace heat,
the time is configurable. The timer is configurable via Option 17. This timer is
overridden if temperature error is greater than 5
(usually due to a large change
in desired temperature) and equipment stages up in 60 second intervals.
The ten
−
minute staging timer does not require the thermostat to change to a
higher stage after 10 minutes. If the system is able to meet the demand (maintain
setpoint) it may not change stages after the 10 minute timer has expired. If there
is sufficient demand for a higher stage at the end of 10 minutes or at any time
after the 10 minute timer has expired, the thermostat will energize the next higher
stage.
