Installation

Mounting

Junction Box:

1. Pull the wire through the wall and out of the junction box, leaving about six inches free.
2. Secure the base to the box using the provided mounting screw.
3. Terminate the unit according to the guidelines in the Termination section.
4. Attach cover by latching it to the top of the base.

Drywall Mounting:

1. Place the base plate against the wall where you want to mount the sensor.
2. Mark out the two mounting holes and the area for wiring.
3. Drill holes and insert drywall anchors.
4. Pull the wire through and secure the base to the anchors using mounting screws.
5. Terminate the unit according to the guidelines in the Termination section.
6. Attach cover by latching it to the top of the base and secure it with lock-down screws.

Termination
The termination process involves connecting and configuring the wiring of the sensor unit. Follow the guidelines provided in the manual for proper termination to ensure correct functionality.

Front Panel
The front panel of the sensor includes a large format LCD display that shows space temperature readings. The setpoint adjust keys allow users to increase or decrease the setpoint as needed. Additionally, there is a tenant override button that initiates a specific sequence at the MicroTech unit controller.

FAQ

• Q: Can this sensor be used with both CAV and VAV systems?
  A: Yes, this sensor is designed to work with both constant volume (CAV) and variable air volume (VAV) applications.

• Q: How do I adjust the setpoint on the sensor?
  A: To adjust the setpoint, press the setpoint adjust keys on the sensor. The initial press will show the current reading, and subsequent presses will change the setpoint value.

Introduction

• The space temperature sensor is designed to work with the MicroTech® unit controller and is a 10k thermistor used to measure the space conditions.
• This device is not a traditional 7-day programmable thermostat. The sensor can be used on either constant volume (CAV) or variable air volume (VAV) applications.
• On CAV systems it acts as the control device for the heating and cooling operations for occupied and unoccupied time periods.
• On VAV systems it is not traditionally used as the control device but used for the unoccupied heating and cooling space sensor.
• The sensor features a large format LCD display that senses the space temperature and displays the space temperature. It also has the setpoint adjust keys to increase or decrease the setpoint. When the adjustment keys are first pressed, the display will show the current reading for the setpoint. Further pressing of these keys will change the setpoint value.
• The sensor also has a tenant override button. Pressing this will initiate the tenant override sequence at the MicroTech unit controller.

Installation

Mounting
Junction Box

1. Pull the wire through the wall and out of the junction box, leaving about six inches free.
2. Pull the wire through the hole in the base plate.
3. Secure the base to the box using the #6-32 x 1/2 inch mounting screw provided.
4. Terminate the unit according to the guidelines in the Termination section of this manual.
5. Attach cover by latching it to the top of the base, rotating the cover down and snapping it into place.

Drywall Mounting

1. Place the base plat against the wall where you want to mount the sensor.
2. Using a pencil, mark out the two mounting holes and the area where the wires will come through the wall.
3. Drill two 3/16” holes in the center of each marked mounting hole. Insert a drywall anchor into each hole.
4. Drill one 1/2” hole in the middle of the marked wiring area.
5. Pull the wire through the wall and out of the 1/2” hole, leaving about six inches free.
6. Pull the wire through the hole in the base plate.
7. Secure the base to the drywall anchors using the #6 x 1 inch mounting screws provided.
8. Terminate the unit according to the guidelines in the Termination section below.
9. Attach cover by latching it to the top of the base, rotating the cover down and snapping it into place.
10. Secure the cover by backing out the lock-down screws using a 1/16” Allen wrench until they are flush with the bottom of the cover (Figure 2).

NOTE: In a wall-mount application, the mixing of room air and air from within the wall cavity can lead to erroneous readings, condensation, and premature failure of the sensor. To prevent this condition, plug the conduit hole with insulation in the junction box.

Termination
The field supplied wire is recommended to be a twisted pair of at least 22 AWG and sealant filled connectors for all wire connections. Large gauge wire may be required for long runs. All wring must comply with the National Electrical Code (NEC) and local codes. DO NOT run the wiring in the same conduit as the AC power wiring. Power wiring in the same conduit will result in inaccurate temperature readings along with signal levels. Install the lugs below the bus bar to assure anti-rotation.

• Front Panel
  The display is standard for all sensors. The functional keys on the display include the setpoint adjustment buttons and the tenant override button, as well as a numerical display to view changes.

• Setpoint Buttons
  When pressed, the setpoint will display for three to four seconds. When pressed again, the setpoint will change in one degree increments. It will only change within the setpoint range that was ordered.

• Tenant Override Button
  When the override button is pressed for 3-5 seconds the tenant override function will be initiated per the MicroTech unit controller. The amount of time that the unit will come out of the unoccupied mode and operate in the tenant override mode is adjustable at the unit controller.

• Numerical Display
  The default display shows current temperature. When the up/down buttons are pushed, then the display will show and adjust the current setpoint and hold the display for 3 to 4 seconds. The unit can also be set up to display setpoint only or for setpoint lockout.
