Control the Heat From Your Computer
Manage comfort and control the energy costs that heating and cooling
represent with the System Controller (sold
separately). The System Controller connects to your distribution panel and
computer, and its intuitive interface allows you to establish individual
thermostat schedules and set basic system-wide settings.
Convenient Message
Center
A convenient alphanumeric display provides simple setup and addressing
through menu-driven options. The message center can also be used by a home
automation system to display virtually any type of system information,
including security system status, weather conditions, HVAC servicing alerts,
Caller ID information, system status, etc. The Message Center
window consists of 2 lines of up to 16 characters, and it comes with scroll
buttons that allow you to scroll through menu selections.
Elegant Backlighting
Full backlighting of both displays eliminates the inconvenience of
viewing in dimly lit spaces. This feature is user-selectable to turn on based
on light level or any time there is a button pressed.
Large, Easy-to-Read Display
The large main display assures you can easily view set points,
outdoor/ remote temperature, fan status and the network communications at a
glance. The main display provides all information about the comfort settings
and current conditions, including room temperature, mode of operation,
heat/cool set points, fan ON or AUTO, remote or outdoor temperature (with
optional sensor), relative humidity (with optional sensor) and more.
Integrated Communication Card
The Aprilaire Communicating Thermostat has
an integrated communication card, which simplifies wiring, reduces components
and extends the wire run distance to as much as 4,000 feet from the
distribution panel wiring bus. Addressing each thermostat is now done in the
message center through the setup menus.
Also Works in Standalone Operation
As always, the Aprilaire Communicating
Thermostat provides you with peace of mind as a standalone controller,
whether or not the computer controller or automation system is up and
running.
