Carrier bryant Evolution Connex Control SYSTXBBECC01-C Installation Instructions Manual page 22

5.4.1. Hydronic Heat Application
The Evolution Connex Control supports two types of Hydronic Heat
applications:
1. Hot water coil in combination with an FE fan coil and heat pump,
or hot water coil as sole heat source with an FE fan coil.
2. Non-zoned FE fan coil combined with radiant hot water heat.
In either application, a Hydronic Heat kit should be installed in place of
an electric heater. See FE fan coil Product Data for accessory part
number. The system will self-identify that hydronic heat has been
installed during electric heater selection. The system will treat the hot
water coil as either auxiliary heat in a heat pump application, or the sole
heat source. Setup options for Hydronic Heat applications are described
in the setup section of this instruction.
NOTE: The daily airflow verification test will take place even when the
radiant hydronic heat option is selected.
5.5. Searching for SAM Module (If Applicable)
"Searching for SAM Module" will appear on the screen to determine if a
System Access Module, used for home automation only, is connected to
the system.
The SYSTXBBSAM01 is not compatible with this control. The
compatible modules are SYSTXNNRCT01. The SAM is used for home
