AQS51/61
CO2 / TEMPERATURE SENSOR WITH BUILT-IN CONTROLLER
FOR WALL MOUNTING
INSTALLATION INSTRUCTIONS
GENERAL INFORMATION
The AQS51 and AQS61 CO
2
/ Temperature Sensors are
used to measure the concentration and temperature of
carbon dioxide in indoor air. The units can be configured as
controllers with programmable outputs for both ON/OFF relay
control and the linear control of e.g. mixed air dampers and
fans. The wall mounting housing has been designed with
snap-in features to minimize installation time.
The units can be directly connected to common VAV
(Variable Air Volume) controllers, Direct Digital Control (DDC)
devices, or standalone control systems. The linear output
functions are pre-programmed as CO
2
and temperature
transmitters. In addition, the AQS51 and AQS61 have a relay
output pre-programmed as a CO
2
limiter. All functions can be
modified from a PC (Windows 95, 98, NT) using the AQS-
USPxx (version 4.0 or higher) software together with the
AQS3/4-CABLE communication cable.
