Mounting the Outdoor Sensor
(Not required if window protection isn’t needed)
Location
Mount the sensor where:
•it cannot be tampered with.
•there is good air circulation.
•surface is flat.
•wire distance between sensor and humidistat is less than 200 feet.
•it can measure true outdoor ambient temperature.
Do NOT mount the sensor:
•in direct sunlight.
•where snow, ice or debris can cover it.
•where hot or cold air blows on the sensor. (For example, a discharge line from an outdoor compressor unit, vent or fan can cause inaccurate temperature readings.)
16
Steps to mount the sensor
1.Remove the sensor from the mounting clip.
2. Mark the area on the location selected for mounting the sensor mounting clip.
3. Mount the clip. Image on right shows typical locations for outdoor sensor.
M7514A
17
Wiring the sensor
Caution
Electrical Interference (Noise) Hazard. Can cause erratic system operation.
•Keep wiring at least one foot away from large inductive loads such as motors, line starters, lighting ballasts and large power distribution panels.
Use shielded cable to reduce interference when rerouting is not possible.
•Be sure wires have a cable separate from the thermostat cable.
•Do not route temperature sensor wiring with building power wiring, next to control contactors or near light dimming circuits, electric motors or welding equipment.
•Avoid poor wiring connections.
•Avoid intermittent or missing building earth ground.
18
Caution
Electrical Shock Hazard. Can cause electrical shock or equipment damage.
Disconnect power supply before connecting wiring.
Wiring must comply with applicable codes, ordinances and regulations:
1.Wire the C7089 Outdoor Sensor to the S terminals on the humidity control. If leadwire provided with C7089 is not long enough (60 in.), run a cable to a hole at C7089 location.
•Using color-coded, 18-gauge, shielded thermostat wire is recommended. For example of general wiring of C7089, see image at right.
•Pigtail wiring can be used.
2.Mount C7089 in its mounting clip.
3.Plug wiring hole using nonhardening caulk or putty.

Allow C7089B Outdoor Sensor to absorb outdoor air for a minimum of twenty minutes before taking a reading.
With an accurate thermometer (±1°F [0.5°C]), measure the temperature at the sensor location, allowing time for the thermometer to stabilize before reading.
Then verify the sensor accuracy by going into installer Test #20. This will show you the outdoor temperature.
Calibration
The C7089 Outdoor Sensor is calibrated at the factory. However, you can offset the outdoor sensor reading using Function 35 in Installer Setup.
21
You’ve just installed your Humidity Controller!
This Humidity Control has been preprogrammed to the ideal settings for most homes.
If you installed this control with an outdoor sensor, the control will operate in AUTOMATIC MODE, which automatically adjusts humidity to help prevent window condensation.
If you installed this control without an outdoor sensor, the control will operate in MANUAL MODE, giving the homeowner simple, direct control of their humidifier (RH% Setting Only).
Advanced Installer Setup
See next page to customize feature operation.
Installer System Test
If Advanced Installer Setup is not required, skip to “Installer System Test/Checkout” on page 27.

NOTE: Most humidifiers require airflow in the system to operate. Make sure to turn on the system fan when testing humidifier operation.
Caution: If running a dehumidifier, compressor protection is bypassed during testing; avoid cycling the compressor too quickly.
Note: Some dehumidifiers may already have built in compressor protection.

Display is blank
Humidity settings do not change
•Check circuit breaker and reset if necessary.
•Check for 24VAC between R and C at the wall plate.
•Make sure power switch at heating and cooling system is on.
•Make sure furnace door is closed securely.
Make sure the humidity is set to an acceptable range:
•Check current range stop settings in Installer Setup.
•Auto Mode: 1–10 (up to 11 if Humidity Boost is enabled)
•Manual Mode: 20%–60%
•Dehumidification Mode: 40%–80%
