I have a building that utilizes a variable volume, outside air unit with a HW coil to serve primary air to number of fan terminal units at the zone level. The FTUs also have a HW coil to provide reheat capabilities on a zonal level. Heating for the outside air unit and the FTUs is provided through a central HW boiler. There is no mechanical cooling. In eQuest I've tried modeling it as a powered induction unit, but I can't get it to offer central heating. I also tried the reheat fan system, but it is a constant volume system. I can't accurately model a variable volume, centrally heated system with zone reheat and fans. Any thoughts?

Thanks.
