WIRING
CAUTION
Voltage Hazard.
Power supply can cause electrical shock
and injury.
Disconnect power supply before installation or
servicing.
All wiring must comply with applicable local codes,
ordinances and regulations.
IMPORTANT
Use 18- to 22-gauge insulated wire for proper
wiring. Stranded-tinned wire is recommended.
Connect the humidistat to the furnace for the following two
reasons:
1.
The control can determine the outdoor temperature.
2.
The control knows when the furnace blower is oper-
ating, eliminating the need for current sensing
relays.
IMPORTANT
When installing a steam-powered humidifier, be
sure to cut steam jumper-wire for correct
operation.
To wire the Automatic Humidity Control:
1.
Connect 24 Vac power to the 24 Vac HOT and
COM terminals on the H1008A,D.
2.
Connect the humidifier to the two HUM terminals on
the H1008A,D as shown in Fig. 5 through 8.
3.
In furnace systems with two transformers, connect
CG to the cooling system transformer common and
connect CW to the heating transformer common.
Be sure G and W connect to the R terminals of both
transformers. (If only one transformer is used, leave
the jumper on CG and CW. See Fig. 10.)
4.
To wire the C7089H Outdoor Temperature Sensor,
connect it to two OUT terminals on the H1008A,D.
IMPORTANT
For correct wiring, use 18- to 22-gauge
insulated wire. Stranded-tinned wire with a
maximum length of 300 ft (91m) is
recommended.
