CO
2
sensor
CO
2
sensor can be either in air return duct or wall
mounted. It maintains a CO
2
concentration below a
preset value to ensure acceptable comfort.
Controls the opening of the fresh air damper of the
economizer. The outside air damper will modulate in
order to maintain the CO
2
concentration below the
setpoint.
To open damper it should combine the amount of
desired fresh air and the free cooling mode to modulate
from 0 to 100% maximum opening of the dampers.
It is possible to preset a minimum opening during
commissioning.
The CO
2
sensor is set for 0-10V analog outputs and
provide sensing of carbon dioxide over a range of
0-2000 ppm. The sensor requires a 24 VDC power
supply. Consult wiring diagram supplied with the unit
for details.
The resolution of analog outputs reaches 10 ppm CO
2
.
The information is then sent to the controller CH536 to
control the opening position of the fresh air damper.
Avoid locating the duct sensor on surfaces with an
uncooled, unheated area behind them or in “dead”
spot behind doors or in corners. The CO
2
wall mounted
sensor should be placed on a at surface, 1.4 m from
the oor in an area of the room where there is free air
circulation.
CO
2
sensor maintenance
This CO
2
sensor has excellent stability and requires no
maintenance. In most environments the recommended
calibration interval is ve years. A trained service
technician can use a portable CO
2
meter to certify
sensor calibration. If, when checking the sensor, the
reading differs too much from the reference value, the
sensor can be recalibrated in the eld. A calibration kit,
software, and calibration gases are required. If certied
accuracy is required, the sensor must be calibrated
against accurate and traceable calibration gases in a
laboratory. Consult Trane BAS for further details.
Fire thermostat
U12 is the dedicated I/O. Optional re thermostat should
be congured if present according to wiring diagram.
Clogged lter detector
This device is mounted in the lter section. The sensor
measures the difference in pressure before and after
the lter section. The information is sent to the optional
service terminal or the BMS.
Smoke Detector
Installation: This device is used to detect smoke in the
air stream. Detector is delivered by trane and must
be installed by the customer to comply with local
regulation. The detector must be connected to the
central panel according the wiring diagram.
Operation: When smoke is detected, it shuts off the unit,
and an alarm is activated in the controller to inform the
user through the local or remote control.
Other accessories available
- DTS : duct mounted wired temperature sensor
The duct mounted sensor - mainly for unit with auxiliary
heat - must be installed away of any duct singularities
and generally at 2 m of any duct elbow or duct inside
element both upstream and downstream.
- TZS01 : wall mounted wired temperature sensor
- THP05 : wall mounted thermostat
Refer to separate documentation for more information.
Alarm and Warnings
Alarms stop the unit or reduce the heating/cooling
capacity. Alarm can be either manual reset (requires
human intervention to re-start the unit) or automatic
reset.
Warning run the unit in fall-back mode.
Example : if outdoor air humidity sensor is not working,
the economizer runs in dry-bulb mode.
Events are accessible through optional local service
terminal which display the current events and
display history of past events (up to 99 alarms
and 99 warnings).
