INTRODUCTION
Carrier's 7-day, 5/2-day, l-day programmable and non-programmable
Performance Series Thermostat Control is a wall-mounted, low-voltage
temperature control in either a single unit or a two-piece unit. In two-piece
configuration, the relays are located near the equipment and a two-wire
connection is used between the Display Module and the Equipment Control
Module. Single-piece installation requires more wiring and results in a higher
profile. The Edge 'M Thermostat has no need for batteries to store
user-configured settings in memory. During power loss its internal memory
saves settings for unlimited time, and the clock continues to run for at least 24
hours. An extension of Carrier's proven line of thermostats; it provides separate
setpoints for heating and cooling.
In the Edge Thermostat Control programmable configuration, different heating
and cooling setpoints and times are programmable for 4 periods per day or 2
periods per day. Programming can be done for 7 days per week, 5/2 days per
week, or 1 day. The programmable Thermostat Control can also be user
configured as a non-programmable Thermostat Control.
The non-programmable Thermostat Control features Touch 'N' Go 'Msettings
for quick and easy temperature change without complicated programming
schedules. And, its Touch 'N' Go technology enables the user to switch between
three different user-configurable settings through intuitive buttons located just
below the display.
