The UltraTemp
Heat Pump can be controlled by an
®
IntelliTouch or EasyTouch system via the RS-485
communication cable. In this configuration, IntelliTouch
or EasyTouch overrides preset Temperature Set points
on the heat pump.
The transfer of this data takes several seconds and
causes a delay from when the command is given from
the IntelliTouch or EasyTouch indoor control panel
until the heat pump physically responds. This happens
automatically but may take 1-2 minutes to complete.
Note: Heat pump control board set points will be
shown as "N/A" and will be functionality disabled.
For more information, refer to the IntelliTouch User's
Guide (P/N 520102) or the EasyTouch User's Guide
(P/N 520584) or the EasyTouch Wireless System
User's Guide (P/N 520688).
Connection from heat pump board to the IntelliTouch
or EasyTouch system is via the optional four-wire cable
(P/N 520199).
