When Installing this Product...

1. Read these instructions carefully. Failure to follow

them could damage the product or cause a hazardous

condition.

2. Check the ratings given in the instructions and on the

product to make sure 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.

IMPORTANT

All wiring must agree with applicable codes,

ordinances and regulations.

Location and Mounting

W6215, W7215, W7460 Economizer Logic Module

W6215, W7215, and W7460 Logic Modules mount directly on

a sheet metal duct or panel. When planning the installation,

allow enough clearance for maintenance and service. Mount

device in a location protected from rain, snow, and direct

sunlight. Secure device to sheet metal using the three supplied

mounting screws, see Fig. 2.

NOTE: See Fig. 3 for representative locations of connected

system devices.

C7400 Enthalpy Sensor and

C7650 Dry Bulb Temperature Sensor

W6215,W7215,W7460 Logic Modules accept signals from

either the C7400 Enthalpy Sensor or the C7650 Dry Bulb

Temperature Sensor. The wiring is the same for either sensor.

IMPORTANT

When using differential sensing, both sensors must

be of the same type (enthalpy or dry bulb).

OUTDOOR AIR SENSING

1. Mount sensor in any orientation that exposes it to freely

circulating air and protects it from rain, snow, and direct

sunlight.

2. Connect it to the S

RETURN AIR SENSING

1. Ensure differential enthalpy control has a second

sensor in the return air duct.

2. Connect this sensor to the S

W6215, W7215, or W7460.

Indoor Sensor Input

The ISI can be any sensor that provides a 2-10 Vdc output.

The ISI modulates the outdoor damper to provide ventilation

based on occupancy. The designer determines contaminants

to monitor, selects appropriate sensor, determines the sensor

threshold, and adjusts the ISI potentiometer accordingly. The

ISI LED lights when the ISI signal is above setpoint. Mount the

sensor according to the manufacturer specifications. If not

available, use the following guidelines:

1. Mount sensor in an area with unobstructed air circulation.

2. Connect it to the AQ and AQ1 terminals of the W6215,

W7215, or W7460 (see Wiring section for details).

3. Adjust the ISI potentiometer setpoint to correspond to

ISI voltage output at the threshold.

IMPORTANT

Ensure proper polarity of sensor connections.

Incorrect polarity negates the sensor signal.
