Maximum Run Time :
Sets the maximum time heating or cooling will run before turning off. To
adjust, use the up and down arrows. Example : If cooling or heating is engaged, but does not
reach the Cutoff Point before the Maximum Run Time is reached, the cooling system will turn
off.

NOTE: For multistage systems, the deltas for the first and second stages are cumula-
tive. If the first stage delta is set at 2 degrees, and the second stage delta is set at 2
degrees, the second stage will not engage until the current temperature has passed
the stage setpoint by 4 degrees. However, the Auxiliary Heat and Emergency Heat
deltas are NOT cumulative.
Minimum Run Time (Minutes) :
Sets the minimum time the heating or cooling will run before
shutting off. To adjust, use the up and down arrows. Example : If while cooling or heating, the
temperature reaches the designated Cutoff Point before the Minimum Run Time is reached, the
system will not shut off until the Minimum Run Time is reached. Also, if heat or cool is engaged
and shut off manually, the system will not shut off until the Minimum Run Time is reached.
NOTE: The Maximum and Minimum Run Times are not per stage, but for cooling and
heating run times regardless of first or second stage transitions.
Auxiliary Stage
Stage Delay (Minutes): Sets the allotted time the main heat pump system will run without
reaching the Heat Set Point before the auxiliary stage engages. To adjust (in minutes), use the
up and down arrows.
NOTE: If set to the maximum time, the auxiliary system will be disabled and never
engage.
Stage Cutoff Delay (Seconds) : Sets the time delay before the main heat pump cuts off, leaving
the auxiliary heating stage to run on its own. To adjust (in seconds), use up and down arrows.
NOTE: Some HVAC systems have built-in Minimum Run Times that may be greater than
that set on the Thermostat.
