Hi,
Today I released new versions of my Zoned Heating/Cooling smartapps (ecobeeSetZoneWithSchedule & ScheduleTstatZones v7.3, ScheduleRoomTempControl v3.3) with new HVAC Pressure checks.
- Added new baseline pressure sensor configuration in Rooms Setup page for checking the vent pressure vs. a given sensor’s baseline pressure.
- Modified the Config Page to display the baseline pressure, the vent pressure, and the offset between the vent pressure and the baseline pressure. The offset
should be around 0.5-0.8 inches of water (124.54-200 Pa) which is the maximum static pressure in a standard HVAC (residential). - Ideally, the baseline pressure sensor should be located in the main supply plenum, just after the furnace. Otherwise, you may also place a pressure sensor
in the same room as the vent, but you’d need to fine tune the offset (as the range in Pa above would likely not be right) in the GeneralSetup page accordingly. - The standard pressure offset (124.54 Pa) in the General Setup page can be modified under the safeguards section according to your own HVAC specifications.
- Made some design changes to avoid ST runtime timeouts (due to rate limiting) in the smartapps ( observed sometimes when a lot of rooms/zones/vents are configured).
The new versions of the smartapps are available at my store:
