Board mode pins factory shipped on “M” pin for On/Off control scheme using “A” signal on low voltage control board.

“Red” status light (on when unit has power)

“Green” signal light continuously indicates the flow index the blower is producing. After a pause, the lamp will flash out long digits which will indicate the “TENS” count, which is immediately followed by short flashes between 1 and 99. For example, a flow index of 23 would yield two long flashes and three short flashes.

CONFIGURING BARD PART #8403-067 CO2 CONTROL for ERV MODULATING CONTROL

BARD PART #8403-067

Manual adjust screw. Use when operating in manual mode (“M” jumper installed) along with the “GREEN SIGNAL LIGHT” to adjust to the required CFM of ventilation. CW rotation reduces the “FLOW INDEX”, CCW rotation increases the “FLOW INDEX”.

Carbon Dioxide and Temperature Transmitters accurately monitorthe CO2concentration and temperature in schools, office buildings, and otherindoor environments to help achieve LEED® certification.

SPECIFICATIONS

WARNING Disconnect power supply before installation to prevent electrical shock and equipment damage.

Make sure all connections are in accordance with the job wiring diagram and in accordance with national and local electrical codes. Use copper conductors only.

CAUTION

CAUTION

CAUTION

Use electrostatic discharge precautions (e.g., use of wrist straps) during installation and wiring to prevent equipment damage.

Avoid locations where severe shock or vibration, excessive moisture or corrosive fumes are present.

Do not exceed ratings of this device, permanent damage not covered by warranty may result.

NOTICE

Upon powering the transmitter, the firmware version will flash on

the display. A warm up period of 30 minutes is required for the

 

 

transmitter to adjust to the current CO2 concentration.

NOTICE Self calibration feature of the transmitter requires exposure to normal outdoor equivalent carbon dioxide level once every thirty days.
