Having a problem with McQuay UV controls. Theses unit ventilators were installed last summer in a school with Bacnet interface to an Alerton system. The units are equipped with a hot water coil, OA damper and a face and bypass damper.
These units are enabled for DCV using factory installed CO2 sensor. I believe the CO2 set-point is 1200 PPM.
Is there a way to write custom programs for the micro-tech using the McQuay laptop interface and software?
For example, I might want to try keeping the hot water coil flooded and modulating the F&BP dampers when the unit is not calling for heating in order to minimize draft complaints due to the 5% minimum outside air by tempering the outside air.
The teachers are covering the vents with books to eliminate drafts. These are floor mounted upflow unit ventilators. There is a teachers union grievance pending.
