Installation - Indoor Sensor 077

The tekmar Indoor Sensor 077 includes a 10 kΩ thermistor mounted on a white enamel

steel plate to provide an accurate measurement of the indoor temperature. The 077 can be

mounted flush onto a standard duplex electrical box. Wiring enters from the back. The 077

can be connected to a 10k Room Temperature Unit (RTU) for remote temperature sensing.

STEP ONE

MOUNTING THE SENSOR

Check the contents of this package. If any of the contents listed are missing or damaged,

please contact your wholesaler or tekmar sales representative for assistance.

Type 077 includes:

•

• One Indoor Sensor 077

•

• One Data Brochure D 077

•

• Two 6-32 x 3/4”

screws

•

• Two 6-32 x 1/2” screws

STEP TWO

REMOVING THE FRONT COVER

Remove the two front screws from the face plate and pull the support plate from the

back of the sensor. Ensure the support plate screws do not fall off as the support plate is

removed.

STEP THREE

MOUNTING THE SUPPORT PLATE

•

• The Indoor Sensor should be installed on an interior wall of the desired zone to be

controlled. Do not mount the 077 in a location that may be affected by localized heat

sources or cold drafts. It may be necessary to install a draft barrier and / or insulation

behind the enclosure in order to prevent air from blowing through the wiring hole and

affecting the Sensor reading.

•

• Mount the support plate to the

electrical box using the two support

plate screws provided.
