SQ-1 diffusers are all shipped as dummy units. Determination of
master and drone units is made through plug and play cable
connections.
One power module is required for every six (6) diffusers without electric
reheat or every five (5) diffusers with electric reheat. (See Figure 3)
Power module requires 120VAC line voltage input – hardwired by
others. (See Figure 4)
Master diffusers must be connected to a controller / thermostat. (See
Master Controller / Thermostat section on next page for details.) Drone
diffusers must be connected to a master diffuser. Disconnect the
supply air temperature sensor on all drone units.
White RJ-12 6-pin cables provide 24VAC power between diffusers.
RJ-12 cables should be used between the power module and the first
diffuser and to connect a master unit to another master unit. The RJ-12
jacks are interchangeable – either RJ-12 jack may be used during
installation. (See Example below)
Blue RJ-45 8-pin cables provide 24VAC power and control signal
between diffusers. RJ-45 cables should be used between diffuser and
master controller / thermostat and between master and drone units.
Disconnect the supply air temperature sensor on all drone units.
The RJ-45 jacks are interchangeable – any open RJ-45 jack may be
used during installation. (See Example below)
