C7735A1000 Duct Air
Temperature Sensor
APPLICATION
The C7735A1000 Duct Air Temperature Sensor (DATS)
is a duct-mounted temperature probe used to sense
discharge air temperature in zoning applications for high
and low temperature limit protection. Alternatively, it is
used with certain Honeywell thermostats for delta-T
diagnostics and IAQ control. For more on these
applications, please see the installation instructions for
those products.

INSTALLATION INSTRUCTIONS
1. Assemble the DATS by attaching the metal sensor
probe to the plastic cap. Insert the plate of the
probe into the two tabs on the inside bottom of the
cap. Then rotate the plate clockwise until it clicks
into the single top tab.
2. Locate the DATS on the supply trunk between the
bypass damper and the evaporator coil and/or heat
exchanger. If a bypass damper is not used, locate
the DATS between the zone dampers and the
evaporator coil and/or heat exchanger. See Fig. 2.

3. Drill a 1/4 in. hole in the duct at the location
selected for the sensor.
4. Attach wire using wire nuts and push them into the
cover, then insert the probe into the hole drilled in
step 2.
5. Secure the DATS to the side of the duct, through
the two mounting holes, with the screws supplied.
IMPORTANT
Use 18-22 gauge thermostat wire for shorter
runs. For longer runs or when wiring near volt-
age, use shielded cable.
6. Run wire to zone panel or thermostat. See zone
panel or thermostat installation instructions.
