1 General Information

Safety

The GMW80 series transmitter delivered to you has been tested for safety and

approved as shipped from the factory. Note the following precautions:

Connect only de-energized wires.

Do not modify the unit. Improper modification can damage the

product or lead to malfunction.

ESD Protection

Electrostatic Discharge (ESD) can cause immediate or latent damage to

electronic circuits. Vaisala products are adequately protected against ESD for

their intended use. It is possible to damage the product, however, by delivering

electrostatic discharges when touching, removing, or inserting any objects

inside the equipment housing.

To make sure you are not delivering high static voltages yourself, avoid touching

exposed component contacts during installation and maintenance.

Recycling

Recycle all applicable material.

Dispose of the unit according to statutory regulations. Do not

dispose of with regular household refuse.

2PRODUCT OVERVIEW

Introduction to GMW80 Series

The Vaisala GMW80 series CARBOCAP® carbon dioxide and temperature

transmitters are wall-mount transmitters designed to fulfill the needs for CO2

measurements in standard demand controlled ventilation applications. The CO2

measurement is based on a new generation CARBOCAP® sensor, which uses

a novel, silicon-based microchip emitter instead of an incandescent light bulb.

The internal reference in the CO2sensor guarantees the best stability and

operation also in constantly occupied buildings without frequent readjustments.

All GMW80 series transmitters measure carbon dioxide (CO2) and temperature

(T). GMW86PT includes a temperature set-point potentiometer.

The CARBOCAP® sensors give correct CO2measurements immediately when

powered on. As they have a built-in reference measurement they do not need a

lengthy learning phase before the measured values are correct. Proper

operation can be verified immediately after snapping on the device cover.

measurement module. The area to avoid is marked No cable on the

mounting base.

2 Product Overview

Temperature Setpoint Potentiometer

Some GMW80 series transmitter models include a temperature setpoint function

that gives the occupant of the monitored space a way to adjust the temperature.

The setpoint function is implemented using a passive 10 kΩ potentiometer

(variable resistor) that is mechanically actuated by a setpoint wheel on the lower

part of the transmitter.

The transmitter is simply marked with plus "+" and minus "-" signs to indicate the

direction of adjustment. The rotation of the wheel is mechanically limited to

approximately 180degrees, so in actual use the resistance range of the

potentiometer varies between approximately 2.1 kΩ and 7.2 kΩ. The

corresponding temperature change is decided on the building controller level.

Setpoint wheel at midpoint:

~4.65kΩresistance.

Setpoint wheel at minimum:

~2.1kΩresistance.

Setpoint wheel at maximum:

~7.2kΩresistance.
