BK Jumper

41G - Humidistat Hookup - 24 V Mode ONLY

The factory installed jumper between "R" and 

"BK" on the circuit board must be cut if an op-

tional humidistat is installed.

HUMIDISTAT HOOKUP - 24 V ONLY

If an optional humidistat for humidity control in cooling 

is used, the factory installed "BK Jumper" must be cut.
The BK Jumper must also be cut if a multi-zone 

controller is connected to *CONT402 is installed and 

using the BK enabled feature.

See  the  24VAC  field  wiring  diagrams  for  more
