HUMIDISTAT HOOKUP
If an optional Humidistat is to be connected between “R”
and “BK”, the factory installed jumper between “R” and “BK”
on the circuit board must be cut. If an optional Humidistat is
used, the jumper must also be cut when applying an airflow
command signal to the “BK” input such as with the variable
speed single-zone and multi-zone system controller. On single
speed cooling only/ non-heat pump systems, jumper “Y” to “O”
for proper operation of the delay profiles and the Humidistat.
For two compressor or two speed systems, jumper “YLO” to
“O”.
