[Equest-users] Heat Control Reset

[Patrick O'Donnell]

Bill,

Thanks for the advice.  I found I could create the schedule that way,
but I am finding that the cooling control of PVAV is really what
controls the heating.  Making adjustments on the heating controls really
only changes the sizing/responsiveness of heating air at the central
level during winter; you cannot manipulate heating DA temp setpoint from
the heating controls only from the cooling control min and max reset
range, if that makes sense.

 

Anyways, cheers,

-Patrick

Patrick,

 

Create the reset schedule you want (of TYPE=RESET-TEMP), then select it
in the HEAT-RESET-SCH field by right-clicking, selecting "Edit/View User
Default" and selecting your new schedule as the User-Defined Default
Value. I think you can follow this process for any field that is
grayed-out with "n/a", though you may not get meaningful results if you
override a field when it really is not applicable.

 

Regards,

Bill

Hi all,

I am using a PVAV with HW baseboard heating and would like to implement
a discharge air temperature heating control reset at the central level
(using the AHU's furnace).  I can get the option of selecting the
"Reset" heating control option by controlling my cooling based off the
Warmest zone and plugging in a Hot Deck Max Leaving Temp.  The thing is
there is no further specification of this control such as what OA temp
conditions will control the reset and running hourly reports show that
this Reset heating control isn't really doing anything.    Am I missing
something here or is this heating control not properly supported in the
newest version of eQuest?

Any help would be much appreciated, thanks!

-Patrick
