Marlin,
 
Thank you for the suggestion. That seemed to have done the trick. I have
looked over the SIM file and it appears to reflect what is intended.

REHEAT-DELTA-T for the ZONE command is only defined for the PIU system
type, not the VAVS system. As you indicated, for VAVS systems,
REHEAT-DELTA-T is available only at the system level and therefore
applies to all zones served by that system. The best (and as far as I
know the only) way to suppress reheat for selected zones on a VAVS
system is to remove the heating thermostat schedule assignments from the
zones that have no reheat. Test this by checking the zone-level heating
reported on the SS-G report in the SIM file for the affected zone(s). If
you find this suggestion helpful, please post your findings to the whole
eQUEST users list.

Hello all,

 

Working on a 4-story building that has 2 VAV air handling units with 53
deg F well water for the cooling coil and 200 deg F hot water (from
boiler) for the heating coil. The AHU's then provide air to the various
VAV boxes. The problem is that 1/4 of them have hot water reheat. I am
using VAVS for the AHU HVAC system type, but the only option for reheat
or no reheat is located there in the Air-Side HVAC System properties.
Therefore, it puts reheat on all VAV boxes. I have looked through the
Air-Side HVAC Zone properties, but there does not seem to be any way to
select which zones/VAV boxes have reheat and which do not. Any help
would be much appreciated.

 

Regards,
