Board
The multiple unit control board is an accessory used
when you need to control up to 3-units from a single
thermostat. The board is typically mounted in the unit
control box closest to the thermostat. A maximum of 2
boards may be used together if up to 6-units must be
connected and controlled from a single thermostat.
Low voltage wiring between terminal blocks and
the Daikin wall thermostat should be made in
conformancewith applicable codes. A color-coded low
voltage cable is recommended.
This version of the board uses VAC relays and should
not be used in combination with any other accessories
or equipment that require VDC connections to the “G”,
“W1”, or “Y1” terminals (i.e. Boilerless System Kit).
The multiple unit control board provides the components
necessary to protect the Mark IV/AC board from
electrical damage that may occur when using standard
off-the-shelf relays.
Do not use the unoccupied (U-terminal) feature with the
multiple unit control board.
