Installation

Wiring

**TURN POWER OFF TO ALL HVAC EQUIPMENT BEFORE WIRING**

•

The humidistat controller is powered from the R and C connections

from the furnace and needs continuous power to operate properly.

Proper R and C wiring is shown in Figure 5.

•

The outdoor temperature sensor wires will connect into the ODT

terminals on the humidistat terminal block as shown in Figure 5.

•

The W terminal is the heat signal from the thermostat. Wire the W

terminal from the furnace control panel to the W terminal on the

humidistat terminal block as shown in Figure 5.

•

Fan control wiring should be completed when possible. If the fan

control wiring is not possible then the humidistat should only be ran in

Heat-Only Mode as described in the Operation section of this

document.

•

The wire running from the G terminal on the furnace control board to

the G terminal on the thermostat will need to be disconnected. The G

terminal from the thermostat will then need to be wired directly to the

G terminal on the humidistat terminal block. The G terminal on the

furnace control panel will then need to be wired directly to the GF

terminal on the humidistat terminal block. See Figure 5.

Humidifier Control Wiring (H1+, H2-)

•

The humidifier control terminals are labeled on the humidistat as H1+

and H2-. These terminals will need to be wired directly to the humidifier

as shown in Figure 5. H1+ on the humidistat terminal connects to the

HUM terminal on the humidifier control panel and H2- on the humidistat

terminal connects to the GND terminal on the humidifier control

panel.
