Control Circuit Connections
WARNING!
Do NOT install any controls inside the HERRMIDIFIER
6500 cabinet. Installations of any extraneous devices
inside the electrical compartment may cause erratic
behavior of the circuitry and will VOID the warranty.
The control wiring for the humidifier is to be connected to
the controls wiring terminal strip located in the electrical
compartment. Terminals #1 and #2 are to power an electronic
humidistat (24 VAC). Terminals #3 and #4 are to connect the
control and high limit humidistat (included). Terminals #5 and
#6 are to connect air proving switch (included). All control wiring
should be 22 AWG or larger. (See Figure 8.) Consult with the
factory if you have any special wiring requirements.
