In this case the Red LED will flash a number of times to indicate probable cause.
1. Disconnect power
2. Correct error
3. Re-connect power
RED (Diagnostic)
On Power Up of system, the RED LED will flash. If there is a problem detected the system
will try two times to diagnose and correct the problem (approx. 80 seconds). If problem
persists RED LED error code will flash.
RED 3 Flashes Heat/Aux Sensor Trouble
a) Ensure sensor or Jumper Plug is fully plugged into connector
b) Otherwise, Replace Sensor or Jumper Plug
RED 4 Flashes B1 Output Trouble
a) Check for wiring error
b) Otherwise replace control
RED 5 Flashes System Trouble
a) Replace control

2.9 AUXILIARY TEMPERATURE SENSOR INSTALLATION
The auxiliary sensor is required for systems with air conditioning coils or for systems using
auxiliary forms of heat. The control board is supplied with a jumper on the Cool Sensor
terminal. This jumper must be removed when the auxiliary sensor is used. Note that the control
will not work if there is not sensor or jumper on the Cool Sensor terminal.
Paradigm Condensing Furnace comes with a jumper plug on the “AUX SENSOR” board
connection. To get the auxiliary temperature sensor to become active when using an
alternative source of heat, the “G” line on the 9300i control must be triggered. To trigger the
“G” line on the 9300i a dry contact switch (relay) must be used to make contact between the
“R” (24V supply) and “G” (24V common) terminal screws on the 9300i. The dry contact switch
(relay) is to be activated by the alternate heating source when it is in operation or requires the
blower to come on. This only applies to an alternate heating source; a cooling coil uses the “Y”
terminals to activate the temperature sensor.
