Backup Heat Upstage Timer
The Backup Heat Upstage Timer is available for any system
with 2 heating types and the Backup Heat Droop is set to
2 °F (1.0 °C) or higher.
Backup heat is not used unless the indoor temperature
drops to the Backup Heat Droop setting or the Backup Heat
Upstage Timer expires, whichever occurs first. The upstage
timer starts when the highest stage of the previous
equipment type turns on.
Backup Heat Upstage Timer options are Off, 30 minutes to
16 hours. Default is Off.

Multistage Control
Multistage Control keeps the high stage of the equipment
running until the desired setpoint is reached. This setting is
recommended for Geothermal Heat Pumps to allow the
loop to rest.
To view/adjust “Finish with High Heat Stage” or “Finish
with High Cool Stage,” set ISU 301 Control Options to
“Advanced Options.” See Fig. 107. Select Yes to turn on this
feature. Default is No.
