Honeywell ADEMCO 4500 Thermostat User Guide
Testing the Pre-Existing Thermostat
Switch the front panel ACTIVE/BYPASS switch to BYPASS, and
check that the pre-existing thermostat (not the 4500 thermostat) is
working and able to control the heating/cooling system. If the pre-
existing thermostat does not function, have it replaced, or call your
heating or air conditioning service company.
If you need service for your security system or heating/air conditioning
system:
If your security system or heating/air conditioning systems are in
need of service, set the 4500 thermostat to the BYPASS mode using
the front panel ACTIVE/BYPASS switch.
When bypassed, the 4500 thermostat is totally removed from control
of the heating and/or air conditioning systems. The
pre-existing (original) thermostat will then maintain total control of
the heating and/or air conditioning systems.
When the 4500 thermostat is bypassed, it will be easier for
heating/air conditioning service personnel to service those systems
including their respective control systems. The switch may be
restored to the ACTIVE position when the servicing is completed.
