SCS module will shut down its stages and allow the Back-Up System
to control the drive relays.
• Receive LED
This LED is used to indicate incoming network traffic. It doesn’t necessarily
indicate that the incoming data is intended for this module or that the incoming
data is correct. It just means that data is being passed across the network.
• Transmit LED
This LED is used to indicate outgoing network traffic. Therefore, if the LED is
flashing it indicates that good data has been received by the module and an
acknowledgment has been transmitted.
Important: Note the red and white piano switch in the top right hand corner of
the board near the LED indicators. This is an address switch. It will be used in
the future on controller upgrades. But, when used with the Vent Master 24, the
switches have to be in the “ON” position.
16.3 Possible
Solutions
Sensor Error
If any of the sensors are bad try the following:
• Reset the controller by taking power away at the breaker, or unplugging it.
• Determine which sensor is bad, then check the connection inside the controller door. If
the error is for sensor 3, read the section below to determine alternate course of action.
• Determine which sensor is bad, then check the sensor that is hanging in the house to
make sure that it has not been damaged.
• Replace the bad sensor.
Sensor 3 Error
•
Check to see if you are using sensor 3. If not, deactivate it using switch number 4
(SWX-4) on the status switch bank located on the back of the controller’s door.
Cycle Error
• If a Cycle error has occurred, it will flash the error code until the error is manually reset
by removing power from the controller and then reapplying power.
• If a Cycle error is indicated, check the operation of the timer fan.
• Also, check the operation of the inlets.
High Pressure Error
• If a High Pressure error has occurred, it will flash the error code until the error is
manually reset.
• If a High Pressure error is indicated, check the operation of the inlets.
Low Pressure Error
• If a Low Pressure error has occurred, it will flash the error code until the error is
manually reset.
• If a Low Pressure error is indicated, check the operation of the fans and inlets.
