Does anyone know a method or workaround within OpenStudio or E+ to activate an air handler based on high humidity (Zone RH > SP) when that system is scheduled off but "Use Night Cycle" is enabled?
(E.g. IF AHU Availability schedule = 0, zone temp <= SP, but zone humidity > SP, THEN cycle on system.)
I know with Trace 700 there is, conceptually, a workaround to create schedules with IF THEN statements (IF zone RH >SP, THEN override schedule value to 100). I've used this in the past to pin a sensible load on the zone so that it raised the temps of the zone whenever RH% > SP, thus activating the AHU, but I can't see how that even possible in E+.
This is a typical concern in buildings we work with and trying to lower zone temp to trigger more runtime hours isn't cutting it, nor is it time efficient to play a game of whack-a-mole in scheduling each individual unit available for all the individual hours where zone RH > SP.
Thanks for any input.
