Space Temperature
This is the current temperature of the zoned area that the WCC3 
VAVBOX II is controlling. It is listed in degrees Fahrenheit. 
(Zone temperatures sensors WM Part# OE210, OE211, OE212, 
or OE213) A duct sensor in the return air ducting may also be used 
for return air control of the VAVBOX zone (WM Part# OE230, or 
OE231)
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.
Current Heating Setpoint
This is the current heating setpoint that the VAVBOX II software 
is controlling to. This setpoint is dependent on “Occupied” or 
“Unoccupied” conditions. It is listed in degrees Fahrenheit.
Heating / Cooling Demand
This is the current heating or cooling demand for the VAVBOX 
controller in degrees from the current setpoint. This current setpoint 
could be the occupied cooling or heating setpoint or the unoccupied 
cooling or heating 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.
Current Airfl ow
This is the current airfl ow calculation in CFM (Cubic Feet per 
Minute).
Calculated Airfl ow Setpoint
In pressure independent systems, you may want to have a set CFM 
level in the zoned space.
Current Airfl ow Demand from Calculated Setpoint
In pressure independent systems, this calculation is in CFM and 
is the current airfl ow calculation demand from the Calculated 
Setpoint.
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.
RELAY STATUS
Fan Operation:
This fi eld displays the current status of the series or parallel fan. 
The status will be either OFF or ON.
Heat Stages:
This fi eld displays how many stages of heat are currently active. 
There can be up to 3 stages total.
