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.
