DUCT-MOUNT AND OUTDOOR-MOUNT HUMIDITY/

TEMPERATURE SENSORS

APPLICATION

The H76XXB Duct-Mount and H76XXC Outdoor-Mount 

Humidity/Temperature Sensors are universal Relative 

Humidity transmitters that can be powered with either a 

+18 to 40 Vdc or 24 Vac supply . The devices are half 

wave rectified. The transmitter also includes either a 20K 

ohm NTC thermistor or a 1K platinum PTC (compatible 

with the T775) for optional temperature use.

The humidity sensors are designed with a field selectable 

4 to 20 mA, 0 to 5 Vdc, or 0 to 10 Vdc output signal 
equivalent to 0 to 100% RH. All units are shipped from 
the factory with a default setting to accept AC power with 
three-wire, 0 to 10 Vdc output.

INSTALLATION

When Installing this Product...

1.

Read these instructions carefully. Failure to follow 
them could damage the product or cause a 

hazardous condition.

2.

Check ratings given in instructions and on the 
product to ensure the product is suitable for your 

application.

3.

Installer must be a trained, experienced service 
technician.

4.

After installation is complete, check out product 
operation as provided in these instructions.

CAUTION

Electrical Shock or Equipment Damage 
Hazard.

Can shock individuals or short equipment 
circuitry.

Disconnect power supply before installation.

CAUTION

Equipment Damage Hazard.
Improper wiring can damage the sensor 
beyond repair.

Follow the wiring instructions carefully.

Mounting

The method of mounting depends on the particular 

sensor application. The following procedures include 

outdoor and duct applications. Also refer to the 

instructions for the electronic control.

Duct mounting Configuration

The H7625B, H7626B, H7635B, H7636B, H7655B and 

H7656B can be mounted in a duct to sense humidity and 

temperature.

IMPORTANT

Select a location to expose sensor to average 
duct humidity and temperature. Avoid locations 
where stratification can cause sensing errors.

NOTES:
• Knockouts allow 1/2 in. conduit connection. To avoid 

damaging board during installation, the cover can be 
detached completely:

• Carefully remove wire plug from board.
• Set the cover aside.

1.

Drill a 3/4” diameter hole in the duct where the 
transmitter is to be mounted. 

2.

Insert the stainless steel probe into the hole until 
the foam is in direct contact with the duct.

3.

Attach the transmitter to the duct using the sup-
plied #8 X 3/4” self-tapping screws.

4.

Remove the cover and install your conduit connec-
tor or watertight fitting. The outer ring is used when 
using a 1/2” NPT conduit fitting.

5.

After wiring the unit, place the cover back on and 
gently turn it until it is tight.

Outdoor Mounting Configuration

The H7635C senses outdoor air humidity and 
temperature. Mount this control where it can sense 
average outdoor air humidity and temperature. Normally, 
the north side of a building provides a suitable location.

NOTES:
• H7635C is weatherproof for outdoor use. Knockouts 

allow 1/2 in. conduit connection. 

• To avoid damaging board during installation, the cover 

can be detached completely:

• Carefully remove wire plug from board.
• Set the cover aside.
