WIRING
All 24 volt wiring must be run separate from the line voltage wiring.
All Low voltage wiring must be 18 gauge minimum and must be run separate from high
voltage wiring. The maximum distance from the Beacon II Smart Controller to the Master
Evaporator is 1000 ft.
The terminal strip in the Beacon II Smart Controller is labeled similarly to that of the
Beacon II boards. Connect the corresponding terminals to those on the Beacon board.
For single Refrigeration system:
Connect MULTI OUT 1 from the Beacon II Smart Controller to the MULTI IN on
the Beacon board on the Evaporator. Then connect MULTI IN 1 from the Beacon II
Smart Controller to the MULTI OUT on the Beacon board on the Evaporator. See
typical wiring diagram at the back of these instructions.
On systems with multiple evaporators the Beacon II Smart Controller must be
wired to the Master Evaporator first. DO NOT disconnect the Room sensor from any
of the Evaporators.
SINGLE SYSTEM CONNECTION
M = Master Evaporator S = Slave Evaporator CU = Condensing unit
For MULTIPLE independent Refrigeration systems:
For the first system, connect MULTI OUT 1 from the Beacon II Smart Controller
to the MULTI IN on the Beacon II board on the Evaporator in this first system. Then
connect MULTI IN 1 from the Beacon II Smart Controller to the MULTI OUT on
the Beacon II board on the Evaporator on this first system. DO NOT disconnect the
Room sensor from any of the Evaporators. See typical wiring diagram at the back of
these instructions.
