Multiple Unit Operation
In a multiple unit configuration, the Remote Human
Interface Panel has the capability to communicate and
control up to four (4) Units. Each Rooftop Unit requires a
separate Interprocessor Communication Bridge Module
(IPCB) and a communication link from the Remote Panel.
Terminal strip TB9 is used to wire the second, third, and
fourth Unit to the Remote Human Interface. TB9 is located
on a daughter board at the bottom right hand corner of the
Remote Human Interface Module. Refer to
Figure 5, p. 9
for the terminal designation and location.
To complete the installation of the remote Human
Interface Panel:
– Verify that Dip Switches 1 and 2, located on the IPCB
module(s), are in the “Off” position and Switch 3 is
in the “On” position.
To view the default parameters or to change operating
parameters at the Remote Panel:
– Restore all power to the Unit;
Follow the step-by-step instructions in the appropriate
Programming Manual(s) (latest edition) for Constant
Volume applications or Variable Air Volume applications
that shipped with the unit.
