To be sure the heating/cooling system is maintaining the room 
temperature at the set-back point you have programmed by phone, 
test the system as follows:   

1.  Be sure that the 4500 thermostat is in the ACTIVE mode using its front 

panel slide switch.  Refer to page 3 if in doubt. 

2.  Be sure that the ACTIVE LED turns on, and is not flashing.  

•  A flashing LED indicates a problem with the wiring to the 

4500 thermostat).   

•  A “Check Thermostat” announcement on the phone is also an 

indication to call for servicing of the 4500 thermostat. 

3.  Arm the security system in the ARMED AWAY mode and leave 

the premises. 

When you return home or by calling home while away, verify that the 
temperature inside the premises closely matches the set-back point 
initially programmed.  Be sure that sufficient time has been allowed 
for the premises ambient temperature to stabilize.  If the 4500 
thermostat is not maintaining temperature as was programmed, first 
review the “ARMED AWAY” set-back point using the phone, and 
then check if the pre-existing thermostat is working as described in 
the next section. 

If both thermostats are not working, call your heating/air conditioning 
service company for servicing of your system.  If only the 4500 
thermostat is not working properly, immediately set its front panel 
switch to BYPASS, thereby using the pre-existing thermostat to 
control your heating and cooling system, and call your alarm 
installation or service company for service.
