JUMPERS
FIPG

– Fan On In Purge – Placing this jumper ON 

keeps the Fan running during the two minute 
Purge Mode. The jumper Off allows the furnace 
controls to cycle the fan.  

FIH 

– This jumper ON brings the Fan On with a 

call for heat.  When off the fan is brought on by the 
furnace controls.  

TEST –

Used ONLY to test the panel as this 

accelerates all of the timings.

LOW LIMIT

– Sets Heating Limit at 170°F with 

jumper  ON and 180°F with jumper OFF.  

BOOT Button

– Resets the microprocessor.

NO SENSOR

– Must be ON when not using 

Leaving Air Sensor and OFF when sensor is 
wired.
