Installing the BACnet Thermostat
This section provides important instructions and guidelines
for installing the BACnet Thermostat. Carefully review this
information before installing the controllers.
Mounting the BACnet Thermostat
For the most accurate performance, install the BACnet
Thermostat on an inside wall where it can sense the average
room temperature. Avoid locations with direct sunlight, heat
sources, windows, air vents, and air circulation or obstructions
such as curtains, furniture, etc.
The BACnet Thermostat must not be:
• Mounted on an exterior wall
• Mounted on or near an object with a large thermal mass
such as a concrete block wall
• Blocked from normal air circulation by obstructions
• Exposed to heat sources such as lights, computers,
copiers, or coffee makers, or to direct sunlight at any time
of the day
• Exposed to drafts from windows, diffusers, or returns
•
Exposed to air flow through connecting conduits or empty
spaces behind walls
Rough-in Preparation
Complete rough-in wiring at each location before mounting a
BACnet Thermostat. This includes the following steps.
• Install the supplied mounting base directly to a wall, a
vertical electrical box, or a box with a wall plate kit
• Routing the connecting cable or cables from the BACnet
Thermostat to the equipment it is controlling
•
Block leaks and airflow from conduits with plumber’s putty
or similar material
• If replacing an existing thermostat, label existing wires for
reference when removing the existing thermostat

Installing the BACnet Thermostat
CAUTION
Can cause equipment damage .
To prevent mounting screw heads from touching the circuit
board in the controller, use only the mounting screw supplied
by Daikin Applied. Using screws other than the type supplied
may damage the BACnet Thermostat.
To install the controller on a mounting base, do the following:
1. Turn the Allen screw in the base of the sensor clockwise
until it clears the case.
2. Swing the BACnet Thermostat away from the mounting
base to remove it.
3. Route wiring for the BACnet Thermostat through the
mounting base.
4. Position the base with the embossed UP toward the
ceiling and fasten it directly to a vertical 2 × 4 inch
electrical box.
5. Connect the wires for the BACnet Thermostat to the
terminals in the mounting base.
6. Place the top of the sensor over the top of the mounting
base and swing it down over the Allen screw bracket. Be
careful not to pinch any wiring.
7. Turn the Allen screw counterclockwise until it backs out
of the mounting base and engages the case.
