Master to Slave Interconnect
A slave fan/heater unit can be added to operate
in unison with the master fan/heater unit. The in-
terconnect between the master and slave fan/
heater units remains the same regardless of the
type or presence of a control center. To wire a
slave fan/heater unit to a master fan/heater unit
do the following:
NOTE: Do NOT use solid wire for interconnec-
tion.
1. Run four (4) 16ga MTW type wires from
the master fan/heater unit to the slave fan/
heater unit.
2. Connect the wires as shown in figure #26.

mended for use on the network connections. The
network connections for this configuration are at-
tached to terminals number 8 and 9 in the master
unit and terminals number 3 and 4 in the slave
unit. Ground each end of the shielded cable to
the housing. A shielded 16 gauge 2 wire cable
can be purchased from GSI. Part # WR-16 / 2S.
