Comments
See Purge mode.
Equipment terminals are not
energized.
If SYSTEM LED flashes orange,
DATS is not connected or is out-
of-range.
Panel enters Purge mode after
each call for heat and cool; this
allows heat exchanger to
dissipate more conditioned air
into the zone.
Heat is delivered only in zone 1.
When another zone calls for heat
while zone 1 is calling, that zone
damper opens.
For electric heat applications, use
thermostat that calls for fan with
all calls for heat.
None.
Cool is delivered only to zone 1.
If another zone calls for cool while
zone 1 is calling, the damper to
that zone opens.
In retrofit applications, where only
three wires are available, Y
signal from thermostat activates
Y and G call from panel
None.
