Appendix A: VAV Zone II Points/Properties
Point Name/Description
Inhibit Cooling Call from this zone? - VVT system only. If Yes, the VVT Master ignores
this controller as a cooling caller.
Active Cooling Caller? – VVT system only. Determines if the zone will be counted as a
cool caller for system cooling when the zone has a local demand for cooling.
Linkage Callers – VVT system only. The minimum number of zones required to make
the air source go into heating or cooling mode. 1 is typical for systems with 8 zones or
less. For larger systems, increase the number by 1 for each 6 zones. For example, 3
linkage callers for a 20 zone system.
System Mode Reselect Timer (minutes) – Applies only to a VVT master. Defines how
long the system continues to operate in the current mode before it reassesses all zones
while the current demand is still active.
Linkage RH Type – Determines if the VVT or VAV Master sends to the air source the
average or maximum values of all linked zone controllers that have a relative humidity
(RH) sensor.
Linkage IAQ Type – Determines if the Master controller sends to the air source the
average or maximum values of all linked zone controllers that have a CO
DCV and IAQ control.
Air Source Mode – If Airside Linkage Status is Active, this is the current mode of the
linked air source. If Airside Linkage Status is Not Active, this is the mode of the air
source as determined by the zone controller's SAT sensor.
Air Source Supply Air Temp – Displays the air source's SAT when Airside Linkage
Status is Active.
Air Source Static Pressure – Displays the air source's supply static pressure when
Airside Linkage Status is Active.
Air Source Outdoor Air Temp – Displays the air source's OAT when Airside Linkage
Status is Active.
