INSTALLATION INSTRUCTIONS (CONTINUED)
ELECTRICAL WIRING
Disconnect all power to the Steam Humidifier
before wiring the Fan Pack. Use standard 24
volt thermostat wire.
Mount the humidistat in the area to
be humidified according to installation
instructions included with the control. Install
the humidistat in the same room or area as the
Fan Pack discharge, but at least ten feet away.
Wire the Manual Humidistat to the Model
800 using standard 24 volt thermostat wire.
See Figure 8. Remove the 40VA transformer
from the Steam Humidifier and replace with
the 75VA transformer supplied with the Fan
Pack (necessary for service part 5658 only). If
using the Model 65 Digital Manual Humidistat,
place the provided wire harness between
the control board and the 24VAC output
of the transformer. Connect R and C of the
humidistat to the red and white wires of the
wire harness.
When using the Model 801 Modulating
Steam Humidifier with the Modulating Control
(#5558), use the wiring diagram in Figure 9.
DO NOT USE the included wire harness.
