A Guide To Operating
Your VVT System
NOTE TO INSTALLER
This manual should be left with the equipment owner.
GENERAL
This manual will assist you in using your Carrier Comfort
System thermostat. There are 2 basic types of thermostats
that you may encounter. They are called the monitor ther-
mostat and the zone controller.
The monitor thermostat can be identified by the system
switches (FAN, HEAT, COOL) which are located along the
bottom edge of the front cover. The monitor thermostat can
be equipped with or without a timeclock. The timeclock dis-
play is located in the upper right corner of the monitor ther-
mostat. The monitor thermostat display is located in the up-
per left corner. The set point and programming buttons are
located around the display.
The zone controller does not have system switches or a
timeclock. The zone controller display is located in the up-
per left corner of the zone controller. The set point and pro-
gramming buttons are located around the display.
There are three typical operations you may perform on
your VVT (variable volume and temperature) system
thermostat:
• change set points for heating and cooling
• override the unoccupied schedule
• change occupancy schedules
NOTE: Your ability to perform these functions may be lim-
ited by the security access level function which is config-
ured by the installer. If ‘‘access denied’’ is shown on the dis-
play screen, you are not allowed to access that function.
The monitor thermostat and zone controller are part of a
VVT system. The VVT system allows a single-zone heating/
cooling unit to operate as a multiple-zone system. The con-
ditioned space is divided into zones. Each comfort zone is
monitored by a zone controller. The monitor thermostat moni-
tors the operation of its own zone and of each associated
zone controller and determines system operation from in-
formation received from each device that it controls.
