The 4500 thermostat provides control for both heat and air conditioning. It is intended for use with Honeywell security systems that include the enhanced 4286 phone module. You can set the 4500 thermostat using any touch-tone phone, either on premises or remotely. The 4500 thermostat is not a replacement for the existing thermostat, which remains in the installation, but can be selected to provide a “set-back” function whenever the system is in the “ARMED AWAY” mode. The existing thermostat controls premises temperature while the security system is “DISARMED”, or in “ARMED STAY” mode.
An important benefit of combined climate control and security is potential energy cost savings. During the heating season, you can “set-back” the 4500 thermostat for times when you are away from home by putting the security system in the “ARMED AWAY” mode. Our set-back feature lets you turn down the thermostat when the house is empty automatically, when you arm the security system in the “ARMED AWAY” mode. During the cooling season, you can set the 4500 thermostat for a higher temperature than the existing thermostat for times when you are away from home, to save on cooling costs by putting the security system in the “ARMED AWAY” mode. In both cases you can call home to adjust the set-back temperature that is in effect while the system is in the armed away mode.
