BTU-4 Installation and Operation Manual Rev D
1
Introduction
The BTU‐4 Burk Temperature unit supports up to four independent
temperature sensors, and provides a low voltage output that tracks
linearly with the AC line voltage.
Each temperature output supplies 10mV per degree Fahrenheit or
Centigrade, based on the type of sensor installed.
The BTU‐4 is supplied with:
•
One AC power adapter
•
One BTO Fahrenheit temperature sensor
•
One 6‐terminal plug for connection to monitoring equipment
Sensors
BTO
–
Outdoor Sensor
The BTO is included with the BTU‐4 system, and
is intended for general purpose
monitoring of equipment or ambient temperatures.
The BTO is attached to 15’ of shielded cable with a stereo phone type connector.
The sensor has a mounting ring and gasket to accommodate #6 or #8 hardware. The
sensing elements are sealed for added protection from dirt and moisture.
BTI
–
Indoor Sensor
The BTI is tailored for monitoring ambient temperatures within a room, while
maintaining a polished appearance.
The BTI is ho
used in a 2 5/8” x 5” enclosure with air vents to facilitate sensing of the
environment.
15’ of shielded cable is provided with a stereo phone type connector on one end. The BTI has a large, easy
to connect barrier strip that accommodates flat or Phillips type screwdrivers.
BTS
–
Stack Sensor
The BTS is designed for sensing heat within the air ducting of your equipment.
The BTS is attached to 15’ of shielded cable with a stereo phone type connector.
The sensor is mounted in the tip of a 3/8” diameter chrome tube. The supplied
mounting hardware consists of a base and a compression fitting to allow the sensor to
be secured at variable depths. This allows the installer to locate the sensor up to 9 1/2
”
from the equipment wall, well within the airflow being monitored.
