4500 Thermostat Installation Instructions
You will not be able to adjust room temperature by phone when the 4500 is
bypassed.
There are several uses for the BYPASS switch function:
•
Allows the user to go back to their pre-existing thermostat at any time.
•
Allows heating/air conditioning service people to bypass the 4500 during
HVAC servicing and maintenance. The 4500 is out of the HVAC control
circuit when bypassed.
•
Allows switching back to the pre-existing thermostat if the security
system is not working or is being serviced.
3 - ACTIVE/BYPASS Indicator
This LED indicates the status of the 4500.
When the ACTIVE/BYPASS switch is in the ACTIVE position, the LED will
be continuously on.
When in BYPASS, the LED will be continuously off.
If the 4500 has lost connection with the 4286 phone module, the LED will flash,
indicating 4500 connections, DIP switch address settings, and 4286 installer
programming entries should be checked.
