Application and Description
The Ademco 4500 thermostat provides control for both heat and air
conditioning. The Ademco 4286 Phone Module is required in the
installation for use with the 4500 thermostat. The user sets the 4500
thermostat using any Touch-tone phone, either on premises or remotely. The 4500 is not a
replacement for the existing thermostat, which remains in the installation. The 4500 can
be user selected to provide remote control and setback functions.
In summary, the ADEMCO thermostat allows the user to:
·
Set back the temperature
(to that set in the ADEMCO thermostat) automatically by arming in the AWAY mode
when leaving home.
·
Resume normal temperature
(as set by the existing thermostat) automatically by disarming the system when returning
home.
·
Check the present
temperature by phoning in from a remote location.
General Information
The 4500 is controlled by a four-wire interface from the 4286 VIP Module
and is powered by 12VDC auxiliary power from the 4286 (which in turn is powered by the
control panel).
The 4500 has separate loops for heat, cool and fan, which connect to the
existing home HVAC system wiring.
There are up to five wires that connect the 4500 to the existing
thermostat at the premises. The user can then switch between the 4500 and the existing
thermostat using the ACTIVE/BYPASS switch previously described.
The 4500 can be used in most applications where ordinary low voltage
thermostats are used. It cannot be used for control of electric heat pumps or line voltage
systems (with 110VAC control lines). Line voltage systems can be converted to low voltage
systems with the addition of a 24 volt transformer and a relay to control the 110 volt
power. These components are available from home supply stores and other suppliers of
heating system components.
