Installation and Operation Manual .
Mounting 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 .
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
