VCB-X Controllers
Building Pressure Control
This confi guration option is available if the EM1 Module has been
installed and confi gured. Touch the radio button to select type of Building
Pressure Control. Default is None.

None—
No Building Pressure Control by this controller.
 
On/Off Control— If the building pressure rises above
setpoint, a relay confi gured as Exhaust Fan will energize in
order to turn on an On/Off exhaust fan. You must confi gure
one of the output relays as Exhaust Fan.
 
Modulating Control— If the building pressure rises above
setpoint, a modulating signal will be used to control an
exhaust fan VFD or a modulating damper. A relay
confi gured as Exhaust Fan can be used to enable this device
so that the modulating signal can control it.
 
Reverse Acting OA Damper Control —Select if reverse
acting Building Pressure Control using the Outdoor Air
Damper is required. If the building pressure falls below
setpoint, the OA Damper (Economizer) signal will be used
to modulate the OA Damper to maintain setpoint.
 
Reverse Acting Supply Fan VFD Control —Contact
WattMaster Factory regarding this reverse acting Building
Control option. This should not be used in most
applications.
Morning Warm-Up
Touch the radio button to select type of Morning Warm-Up control.
Default is None.

None — There is no Morning Warm Up required.
 
Stand Alone Warm-up Control
— The VCB-X Controller
is not communicating to Orion VAV Box controls, but a
Morning Warm Up Relay can be confi gured to signal boxes
by other to open.
 
Warm-up w/Broadcast to Fixed Airfl ow—
The VCB-X
Controller is communicating to Orion VAV Boxes and will
broadcast a command to the boxes to go to a Fixed
Percentage Position or Airfl ow while in Morning Warm Up.
This fi xed position is confi gured in the VAV box controller.
 
Warm-up w/Broadcast to Maximum Airfl ow—
The
VCB-X Controller is communicating to Orion VAV Boxes
and will broadcast a command to the boxes to go to a
Maximum Percentage Position or Airfl ow while in Morning
Warm Up. This maximum position is confi gured in the VAV
box controller.
Binary Input Confi guration
Touch the square button to select the binary inputs on the VCB-X
Controller.
 Emergency Shutdown Input is Required
Select this item for YES if a Smoke Detector/Firestat
or other Emergency Shutdown input is connected to the
Emergency Shutdown binary input. If a Shutdown condition
occurs and the 24V signal is removed from this input, the
Supply Fan and Heating and Cooling Relay Outputs will be
de-energized and an alarm will be generated. Default is NO.
VCB-X Confi guration
 Proof of Flow Input is Required
Select this item if the unit is equipped with a Proof of Flow
Switch and it is connected to the VCB-X. If selected as
YES and the Proof of Flow Switch is open, only the Supply
Fan Relay will be active. If any other relays such as Heating
Stages or Cooling Stages are active, they will be deactivated
when the Proof of Flow Switch input is lost. Default is NO.
 Dirty Filter Input is Required
Select this item if a Dirty Filter switch is connected to the
Dirty Filter binary input. If the Dirty Filter input is active,
an alarm will be generated. Default is NO.
 Defrost Coil Switch Installed
Select this item if a Defrost Coil Temperature Switch is
installed and is connected to the Defrost Coil Temperature
Switch binary input. If this switch closes, it will initiate a
Defrost Mode. Default is NO.
Installed Sensors
Touch the square button to select the desired airfl ow sensor monitoring:
 Monitor Return Airfl ow Sensor—
Select this item if
you have an Airfl ow Monitoring station measuring the CFM
of the Return Air airfl ow stream of this unit . Default is NO.
 Monitor Supply Airfl ow Sensor—
Select this item if
you have an Airfl ow Monitoring station measuring the CFM
of the Supply Air airfl ow stream of this unit . Default is NO.
 Monitor Exhaust Airfl ow Sensor— Select this item if
you have an Airfl ow Monitoring station measuring the CFM
of the Exhaust Air airfl ow stream of this unit . Default is NO.
 Monitor Outdoor Airfl ow Sensor— Select this item if
you have an Airfl ow Monitoring station measuring the CFM
of the Outdoor Air airfl ow stream of this unit . Default is NO.
 Control Outdoor Airfl ow—
Select this item if
you have an Airfl ow Monitoring station and are controlling the
OA Damper to an airfl ow (CFM) setpoint. Default is NO.
 Has Outdoor Air Temperature Sensor— Select this
item if you have any type of Outdoor Air Temperature Sensor
installed.
 Broadcast Outdoor Air Humidity— The VCB-X will
broadcast its Outdoor Air Humidity Reading to other HVAC
units if they are not equipped with their own Outdoor Air RH
sensors. A network communications device (MiniLink PD or
CommLink) is needed in order for this feature to operate.
 Broadcast Outdoor Air Temperature—
The VCB-X will
broadcast its Outdoor Air Temperature Reading to other HVAC
units if they are not equipped with their own Outdoor Air
Temperature sensors. A network communications device
(MiniLink PD or CommLink) is needed in order for this feature
to operate.
