General Information - Bard MEGA-TEC W090A Service Instructions Manual

Air Conditioning System
This Bard air conditioning system is comprised of
MEGA-TEC wall-mounted air conditioners matched
with an LC6000 supervisory controller or Bard PGD/
PGDx stand-alone display. If only one wall-mounted
air conditioner is being used, it can be matched with
either the LC6000 supervisory controller or stand-alone
controller (see Single Unit Operation on page 3 for
information on the PGD and PGDx). If more than one
wall mount is installed, the LC6000 controller must
be matched with the air conditioning units. The wall-
mount units are specifically engineered for telecom/
motor control center rooms.

sensors (one sensor per zone) will need to be purchased and installed in the additional zones. One additional
temperature-only sensor (Bard P/N 8301-058) may also be used in Zone 1 but will also need to be purchased
separately. Additional temperature/humidity sensors require field-supplied 5-wire 18 gauge shielded cable.
