systems automatically enforce a Minimum Off Time. In this case, the heating or cooling will
remain off for the higher of the two settings (Thermostat or HVAC system).
Stage Configuration (Heat Stage 1, 2; Cool Stage 1, 2; Auxiliary; Emergency)
The stage configuration boxes allows for setting the engage delta, minimum run time and
maximum run time for each stage.
Note: These settings take effect as soon as the Advanced Device Configuration box is
closed.
Delta (degrees)—Use the up or down arrows to set the stage engage temperature delta.
This sets how many degrees the current temperature will reach beyond the setpoint before
the stage engages.
Example:
For heat, if the heat setpoint is 70 degrees Fahrenheit and the engage delta is 2 degrees
Fahrenheit, the heat stage will engage when temperature reaches 68 degrees.
Note: For multi-stage systems, the deltas for the first and second stages are cumulative. If
the first stage delta is set at 2 degrees Fahrenheit and the second stage delta is set at 2
degrees Fahrenheit, the second stage will not engage until the current temperature has
passed the stage setpoint by 4 degrees Fahrenheit. However, the Auxiliary Heat and
Emergency Heat deltas are NOT cumulative.
Minimum Run Time—Use the up or down arrows to set the stage x minimum run time in
minutes. . The minimum run time is one (1) minute. This sets the minimum time the heating
and cooling will run before shutting off. 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: Some HVAC systems have built-in Minimum Run Times that may
be greater than that set on the Thermostat.
Maximum Run Time—Use the up or down arrows to set the Heat Stage x maximum run
time in minutes. The maximum run time is 255 minutes. This sets the maximum time the
heating or cooling will run before turning off. Example: If heating or cooling is engaged, but
does not reach the Cutoff Point before the Maximum Run Time is reached, the cooling
system will turn off. 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
The Auxiliary and Emergency Heat stages are specifically for heat pump systems. The switches
on the back of the Thermostat allow the Thermostat to operate a heat pump system.
Note: These settings take effect as soon as the Advanced Device Configuration box is closed.
Stage Delay (Minutes)—Use the up or down arrows to set the stage delay for x minutes.
This sets the allotted time the main heat pump system will run without reaching the desired
heat setpoint goal before the Auxiliary stage engages. Note: If set to the maximum time
allowed, the auxiliary system will be disabled and never engage.
Stage Cutoff Delay (seconds)—Use the up or down arrows to set the stage cutoff delay
in seconds. This sets how much of a delay before the main heat pump cuts off, leaving the
