The CT32 has two USNAP slots to accommodate
home automation radios from various systems.
Please refer to radio documentation for network
for specic installation instructions. The USNAP
ports allow you to connect your CT32 to a wireless
network. This can give you access to your home’s
HVAC system even when you are away. It can also
give you access to web-based efcient energy
management sites that can help you save money
and protect the environment.

damage the thermostat or radio modules. Only one USNAP radio can be used at a time.
1. Power off the CT32.
2. Remove the slot cover and insert radio module in either slot on the back of the CT32. Take care
to ensure that the radio mates well with the connection pins on the thermostat.
3. Power up CT32.
TO CONNECT to a network follow the instructions that came with the USNAP module.
