Jumper Configurations
Jumper Connections
J-1 Connected with a jumper in all modes except when using automatic charge control with two-mode circuit boards.
J-2 Always connected with jumper.
J-3 Connected with violet jumper except when fans are to be disabled during the charge period.
J-4 Input voltage selector: When fan circuit input voltage is 208-240 VAC,
J4-2 to J4-3 are connected. When fan circuit input voltage is 120 VAC, J4-1 to J4-2 and J4-3 to J4-4 are connected.
J-5 Factory wired with plug-in header connector.
J-6 Fan run time based charging jumper: In OP. MODE #1, off-peak heat call can bring core to a 1/3 charge level when no
other charging method is being used. OP. MODE #2 will allow off-peak heat calls to bring core to full charge. OP. MODE
#3 will not allow core charging based on fan run time (positive off).
J-7 24 VDC output from circuit board used for auxiliary control devices or to run peak and pre-peak signals on DC power
rather than AC power.
J-8 When connected, enables fans during pre-peak charging mode.
