BOILER MONITOR CARD PICTORIAL

On boiler systems the jumper (W1) MUST BE installed on the "Last" wired boiler. This

is located on the Boiler Monitor board in the upper left hand corner, adjacent to the

RS485 terminals.

On Multiple boiler systems the W1 jumper must be removed from all Boiler Monitor

boards except on the "Last" wired boiler.

For normal boiler operation the dip switch settings can be utilized to define any of the

boilers as #1 thru # (maximum), independent of the "Last" wired boiler position.
