Termination
Daikin recommends using seven conductor shielded cable
of at least 22AWG and sealant lled connectors for all wire
connections. Larger gauge wire may be required for long
runs. All wiring must comply with the National Electric Code
(NEC) and local codes. Do NOT run this device’s wiring
in the same conduit as AC power wiring. Fluctuating and
inaccurate signal levels are possible when AC power wiring
is present in the same conduit as the signal lines. If you are
experiencing any of these difculties, please contact your
Daikin representative.

Installation
Mounting
Location
Note: Mountthethermostataboutvefeetabovetheoor.
Do not mount the thermostat on an outside wall, in
directsunlight,behindadoor,orinanareaaffected
byaventorduct.
Junction Box, (J-Box)
DANGER
Hazardous Voltage!
Turn off power at the main service panel by remov-
ing the fuse or switching the appropriate circuit
breaker to the OFF position before removing the
existingthermostat.
IMPORTANT!
Thermostat installation must conform to local and national
buildingandelectricalcodesandordinances.
1. To remove cover, insert and twist a coin or screwdriver in
the slots on the thermostat.
2. Pull the wire through the wall and out of the junction box,
leaving about six inches free. Note that the J-box must
be rotated to the horizontal position to accommodate the
proper mounting position. See Figure 1.
3. Pull the wire through the hole in the base plate.
4. Secure the back plate to the box using #6-32 × 1/2 inch
mounting screws.
5. Screw the plate rmly to the wall so the foam plate
backing is compressed about 50%.
6. Terminate the unit according to the guidelines in the
"Field Wiring" section.
CAUTION
 Besureexposedportionofwiresdonottouchotherwires.
7. Attach cover by placing the top of the cover on the back
base and snapping the bottom into position.

Drywall Mounting
1. Place the base plate against the wall where you want to
mount the sensor.
2. Mark out the two mounting holes where the unit will be
attached to the wall. Drill a 3/16" hole in the center of
each mounting hole and insert a drywall anchor into the
holes.
3. Mark out the center hole for the eld wiring entrance and
drill one 1/2" hole in the middle of the marked wiring area.
4. Pull the wire through the wall and out the 1/2" hole,
leaving about six inches free.
5. Pull the wire through the hole in the base plate.
6. Secure the base to the drywall anchors using #6 × 1"
mounting screws.
7. Screw the plate rmly to the wall so the foam plate
backing is compressed about 50%.
8. Terminate the wiring according to the guidelines in the
"Field Wiring" section.
9. Attach cover by placing the top of the cover on the back
base and snapping the bottom into position.
Note:  1.Inanywall-mountapplication,thewall 
  temperatureandthetemperatureoftheairwithin
  thewallcavitycancauseerroneousreadings.
  2.Themixingofroomairandairfromwithinthewall
  cavitycanleadtocondensation,erroneous
  readingsandsensorfailure.Topreventthese
conditions, Daikin recommends
 sealingtheconduitleadingtothejunctionboxwith
  berglass.

RoomTemperature
Adjustment
This sensor is used for water source heat pump
applications requiring the following functionality:
•Cool/Warm Room Temperature Adjustment –
This slide adjustment is used to set the desired room
temperature. To increase the desired room temperature,
move the slide to the right toward “Warm”. To decrease
the desired room temperature, move the slide to the left
toward “Cool”.
• Occupancy Switch – Move the switch to the “Occ” to
allow the unit to operate in the occupied mode. Move
the switch to the “Unoc” to allow the unit to operate in
the unoccupied mode. Move the switch to the “Off” so
heating, cooling and the fan remain off.
• System Switch – Set to “Heat” for heating only operation.
Set to “Auto” for operation of heating or cooling as
needed to satisfy the room setpoint conditions. Set to
“Cool” for cooling only operation. The output voltage
on Terminal 2 will change based on the system mode
selection.
• Fan Switch – Set to “Auto” to allow the fan to cycle with
all requests for heating or cooling capacity. Set to “On”
to allow the fan to operate continuously as long as the
MicroTech III control is not in an alarm condition.
• Status LED – This green LED will light to indicate the
system status. See Table 8 for unit status LED denitions.
• Override Button – When the “Override” button is
pressed, the thermistor sensor across terminal 4 is shorted.
If held for more than 5 seconds but less than 11 seconds,
it puts the water source heat pump controller into a timed
Occupied Override. If the unit is in alarm, then holding
the “Override” Button for more than 11 seconds will clear
all alarms in the water source heat pump controller but
only if the cause of the alarm has already returned to its
non-alarm condition. Some alarms will not reset from the
room sensor.
In this case, power to the unit must be cycled off for 5 sec-
onds to clear the alarm. Continuously resetting alarms from
the room sensor could damage the controller. Please call a
service technician when repeated alarm resets are required to
keep the unit operational.
