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.
Fig. 106.
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.
