This IQ2020 Heater Relay Circuit Board is the newest revision for the 2001-2009.5 IQ2020 Control Box. It’s upgraded design provides a more efficient method of connecting the heater’s power cord to this board, therefore, reducing fatigue on the two “beefed up” relays.
Note: This circuit board does not come with a Pressure Switch Bypass jumper. The jumper must be plugged into P34 port labeled pressure switch.
