Installation and User’s Guide
Connecting the Heat Pump to the IntelliTouch
®
or EasyTouch
®
Load Center via the
RS-485 Connector
The heat pump can be controlled by an IntelliTouch
®
or EasyTouch
®
system via the RS-485 communication
cable. In this configuration, IntelliTouch
®
or EasyTouch
®
overrides present Temperature Set points on the heat
pump and will start or stop 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 but 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).
