The Series BTT Temperature Transmitter can be used for the following applications: monitoring the temperature inside air ducts for HVAC, transmitting temperature inside water lines for chillers, or measuring the outside air temperature
of any new or existing facility. Mounting congurations include duct, immersion, and outside air. For duct and immersion models, probes can be ordered from 2.5˝ up to 18˝
in length. The OSA models can be ordered with an optional radiation shield that allows the sensor to be mounted in direct sunlight.

INSTALLATION
WARNING
in accordance with the job wiring diagram and in accordance with national and local electrical codes. Use copper conductors only.
Use electrostatic discharge precautions (e.g., use of wrist straps) during installation and wiring to prevent equipment damage.
Avoid locations where severe shock or vibration, excessive moisture or corrosive fumes are present. NEMA Type 4X (IP66) housings are intended for outdoor use primarily to provide a degree of protection against wind-blown dust, rain, and hose­directed water.

Duct Mount
The transmitter should be mounted in a location that receives adequate air ow for
proper operation. The transmitter should be mounted such that the conduit connection points down to prevent moisture from entering.
1. Drill a 0.26˝ diameter hole into the duct at the desired location.
2. Insert the transmitter probe through the hole such that the mounting ange is ush
to the duct.
3. Use two #8 x 1/2˝ pan head sheet metal screws to attach the mounting ange to the
duct. Do not over tighten.
4. Twist off the top cover to access wiring terminals.
5. Proceed with wiring according to Figure 1 or Figure 2.
6. Replace top screw cover.
Immersion Mount
The transmitter should be mounted to a thermowell since the process connection is not sealed against water ingress. It should also be mounted such that the conduit connection points down to prevent moisture from entering.
1. Before mounting the transmitter, mount the thermowell to the pipe.
2. Slide the temperature sensor into the thermowell.
3. Hand tighten the plastic threaded connection of the sensor into the thermowell.
4. Twist off the top cover to access the wiring terminals.
5. Proceed with wiring according to Figure 1 or Figure 2.
6. Replace top screw cover.
OSA (Outside Air)
The transmitter should be mounted under an eave, shield, or in an area that is out of the elements or direct sunlight. The transmitter should be mounted with the sensor pointing down to prevent water collection in the sensor cavity.
1. Remove the cover plugs from the face of the unit and the top cover.
2. Position the transmitter where it is to be mounted and mark the mounting holes in each corner of the housing.
3. Drill or punch out marked locations.
4. Place the transmitter box over mounting holes on wall and align. Install wall mount screws (not provided) in mounting holes.
5. Proceed with wiring according to Figure 1 or Figure 2.
6. Replace cover and cover plugs on the face of the unit.
Wiring
The Series BTT Temperature Transmitter can be ordered for current or voltage outputs.
For current output models, the supply power must be between 13-36 VDC and the unit should be wired as shown in Figure 1.
Figure 1
For voltage output models, the power requirement must be between 13-36 VDC or 16-28 VAC. The unit should be wired as shown in Figure 2.
OSA (Outside Air with Radiation Shield)
1. Position the transmitter where it is to be mounted and mark the mounting holes.
2. Drill or punch out marked locations.
3. Place the transmitter box over mounting holes on wall and align. Install wall mount screws (not provided) in mounting holes.
4. Remove the cover plugs from the face of the unit and the top cover.
5. Proceed with wiring according to Figure 1 or Figure 2.
6. Replace cover and cover plugs on the face of the unit.
