[Equest-users] Pumps and Aux.

[Alan Crittendon]

It was my pilot lights.  I went to Furnace Fuel Aux under hvac
para/heat/unitary power and set it to 0.  problem solved.

Alan,

 

If your heat pumps are set to "reverse cycle" defrost, try "resistive" and
see if the Pumps/Aux gas use goes away or changes.

 

I would create a custom hourly report for the system, selecting supply cfm
and OA percentage, to see what the system is actually doing on an hourly
basis.

 

Regards,

Bill

What equipment is in this field on the gas consumption of the report?  I
have a gas water heater and dual fuel hat pumps, that are shown in the space
heat and hot water fields, but cant figure out what the Pumps and Aux is
including.  Could it be the gas used when the heat pumps go into defrost?  

 

Also, I've specified a min cfm in the wizard and now a fresh air and exhaust
under the ERV portion of my air side equip.  could both be going into the
space or does one take precedence over the other?
