J3-3 is modulating gas heat config. input J3-4 is
used with 27.5 to 50 ton units to configure
condenser fan control type.
•
J3-5 is used to configure the unit as a Voyager
™
Commercial unit. (27.5 to 50 ton units only).
Input is also used on 25 ton high efficiency Voyager
™
Light Commercial products to indicate 4 stages of
cooling are required.
J4 Output
The Precedent

6-10 Tons High Efficiency Heat Pump
units utilize a J4 output for compressor staging.

orr (10K @ 77°F/25°C) allows supply
air tempering, also discharge air information for
Building Automation systems (BAS) using COMM5
such as Tracer
®
Summit V13 and Tracker
®
Version 10.
Earlier versions of Tracker
®
(V6.5 and below) and any
Tracer
®
system using COMM3 or COMM4 do not
recognize this input.
The input seen by Tracer
®
(using COMM3 or COMM4)
and Tracker
®
(prior to Version 10) is “Supply Air
Temperature”, which is actually the Mixed Air
Temperature input from the ECA to the RTRM. The
other inputs on J4 are not used.
J5 Output
J5 is the 2-10 VDC output used when the unit has
modulating gas heat.
