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.
