Designed to Interface with Most Heating and Cooling Systems

These relays sense current rather than measure voltage, making them more reliable. They are less expensive than using traditional flow

switches, pressure switches or other types of relays. The relay installs around the blower motor’s common lead and interface easily

into the circuitry.

The current sensing relay case is constructed from high-impact plastic. The lead wire bracket is protected by a soft sponge insert, in

order to prevent damage to the motor/blower wire and/or accidental contact with any metal.

General Installation Procedures

Important:

The wire lead bracket needs to carry a minimum of 5.0 amps for proper operation. If the current draw is less than 5.0 amps,

wrap the lead wire around the bracket so that it passes between the bracket and relay housing two or more times.

Caution:

Turn off all power to the furnace motor circuit and cabinet.

1. Follow the step-by-step instructions for

mounting the humidifier, found in the

humidifier installation manual.

2. Please follow these wiring instructions:

A.Turn off electrical power to the

furnace. Attach the current sensing

relay around the common lead of

the furnace blower motor. The relay

must be located at least 3” from any

transformer. Make sure the relay’s

metal bracket does not touch any

other metal. (See detail A)

B. Confirm the voltage of the switched

load matches the current sensing relay.

C. Wire the current sensing relay as

required for this installation. Refer to

the figures shown below as reference.

For Digital Humidistats, refer to the

Digital Humidistat wiring diagrams.

3. Follow the instructions supplied with the

humidifier to complete the installation.
