Current Cooling Setpoint
This is the current cooling setpoint that the VAVBOX II software
is controlling to. This setpoint is dependent on “Occupied” or
“Unoccupied” conditions. It is listed in degrees Fahrenheit.
Cooling Demand
This is the current cooling demand for the VAVBOX controller in
degrees from the current setpoint. This current setpoint could be
the occupied or unoccupied cooling setpoint. It is listed in degrees
Fahrenheit.
Sensor Slide Effect….(Optional)
If the zone temperature sensor that is connected to the VAVBOX
controller is equipped with a slide offset pot, (WM part# OE212, or
OE213) for tenant comfort control of space temperature then this
fi eld value will range from “0” to “5”, with “0” being disabled, and
1, 2, 3, 4, and 5, being the degrees in Fahrenheit, both plus and minus
from the programmed heating or cooling setpoint depending on the
current mode of operation of the WCC3 VAVBOX II controller.
Duct Temperature
Each WCC3 VAVBOX II controller has an input for a Duct supply
air temperature probe. VAVBOX zones so equipped with reheat
can use cool air, and then “Reheat” it back up to temperature for
desired heating of the zone. These “reheated” zones are usually
located on the outer perimeter of a building’s heating or cooling
needs. This is because interior zones generally require cooling only
type of control.
Damper Position
This is percentage of “OPEN” for the actuator and this corresponds
to how much the air valve is open to let conditioned air into the
space. 10% and the air valve is open very little; 100% and the air
valve is fully open. Please note that there are different manufacturers
of air valves, and these air valves can be of the 60 or 90 Degrees
type on the rotation to fully open. WattMaster VAVBOX II works
with both of these types of air valves.
