WALL MODULES
PRODUCT DATA
GENERAL
The C7110C1040 and C7110C1080 are combined CO
2
/
passive temperature wall modules designed for applications
in indoor ventilation and air conditioning systems. In con-
junction with the Honeywell controllers, they can be used to
control the flow of incoming air, thus improving air quality
while reducing energy consumption. During high-occupancy
periods, air can be supplied to rooms in order to maintain the
desired air quality, while during low-occupancy periods, the
unnecessary conditioning of air can be avoided or reduced.
FEATURES
 Fully compatible with the Honeywell controllers.
 CO
2
sensor employing state-of-the-art Non-Dispersion
Infrared (NDIR) technology.
 Selectable CO
2
measurement range of 400…2000/3000
ppm.
 Self-calibrating: automatic drift correction (ABC
algorithm) based on long-term evaluation.
 Internal Service LED (visible after removing cover).
