If a heat pump is commanded on in a desired heating or cooling mode:
-
The isolation valves for desired heating or cooling mode are commanded
open.
-
Plants with dedicated primary pumps:
The dedicated primary pumps are commanded on when the
associated isolation valves are commanded open.
-
Plants with headered primary pumps:
The headered primary pumps are commanded on as described in
Buildings.Templates.Plants.Controls.Pumps.Generic.StagingHeadered.
-
Once the isolation valves are fully open (based on nominal valve timing
dtVal)
and the lead pumps are proven on, the heat pump is enabled in heating or cooling
mode.
If a heat pump is commanded off:
-
The heat pump is disabled.
-
After the time required for the internal shutdown cycle to time out
(
dtOff to be determined empirically, defaulting to 3 min),
all isolation valves are commanded closed.
-
Plants with dedicated primary pumps:
The dedicated primary pumps are commanded off when the associated
isolation valves are commanded closed.
-
Plants with headered primary pumps:
The headered primary pumps are commanded off as described in
Buildings.Templates.Plants.Controls.Pumps.Generic.StagingHeadered.
