On-Board Link W914 Dehum or Harmony (R to DS)
On-board link W914, is a clippable connection between
terminals R and DS on the integrated control. W914 must
be cut when the furnace is installed with a thermostat which
features humidity control. If the link is left intact the PMW
signal from the control will be blocked and also lead to
control damage. Refer to Table 19 for operation sequence
in applications including A80DS2V, a thermostat which
features humidity control and a single- speed outdoor Unit.
Table 20 gives the operation sequence in applications with
a two-speed outdoor unit.
On-Board Link W951 Heat Pump (R to O)
On-board link W951 is a clippable connection between
terminals R and O on the integrated control. W951 must
be cut when the furnace is installed in applications which
include a heat pump unit and a thermostat which features
dual fuel use. If the link is left intact, terminal “O” will remain
energized eliminating the HEAT MODE in the heat pump.
On-Board Links
NOTE:
In Comfort Sync™ systems with a conventional
outdoor unit (non-communicating), the on-board clippable
links must be set to properly configure the system.
On-Board Link W915 2 Stage Compr (Y1 to Y2)
On-board link W915 is a clippable connection between
terminals Y1 and Y2 on the integrated control. W915 must
be cut if two-stage cooling will be used. If the Y1 to Y2 link
is not cut, the outdoor unit will operate in second-stage
cooling only.
