4500 Thermostat Installation Instructions
5-2
5. Check the heat mode operation of the premises thermostat by varying its
set point and verifying that the heating system turns on and off.
6. If the 4500 thermostat will control an air conditioning system, set the
4500 front panel slide switches to ACTIVE and COOL. Set the premises
thermostat into its cool mode as well. If only heating will be controlled,
skip to step 9.
7. Set the premises thermostat 10 degrees below the present room
temperature. Similar to step 4 above, turn the air conditioner off and
then on varying the 4500 set point 5 degrees above and below room
temperature. Note that it takes at least five minutes for the air
conditioner to turn on from the time it turns off. This feature is present
in the 4500 to protect the air conditioner compressor from excessive
cycling.
8. Switch the ACTIVE/BYPASS slide switch to BYPASS. Check the cool
mode of the premises thermostat by turning the air conditioner on and off
by varying its set point above and below ambient temperature.
9. If there are two 4500’s in the system, test the operation of the second
4500 by repeating the testing steps 1-8 above. The LOG ON thermostat
setting menu selection (2 key) is used to choose the second thermostat so
it can be set. After testing the 4500’s and premises thermostats, set them
to temperatures as desired by the homeowner.
Setting the Premises Thermostat
The 4500 can decrease the amount of heat or air conditioning that would be
provided by the premises thermostat, but cannot increase it. The premises
thermostat should always be set to a higher heat set point and a lower cool
set point than the 4500 set-back temperature. Then the 4500 will be able to
set-back the temperature, and it will adjust room temperature to the set-back
level when the security system is armed away. If the premises thermostat is
set to provide less heat or air conditioning than the 4500 set-back
temperature, the 4500 will remain passive at all times and the premises
thermostat settings will prevail.
Setting the 4500 Thermostat
To enter and use the 4286 thermostat programming mode:
1. There must be at least one thermostat programmed into the system by
