Field Programming
This feature is used for transferring the configuration from the master to the target thermostat. All
thermostats for a job can be mounted and powered up. Configure one thermostat. This will be the
master. The master will be used to copy the configuration to the rest of the thermostats.
Preparing the master to Send:
1. The master must be powered with 24 VAC.
2. Verify the master thermostat is in
OFF
mode.
3. Press
SYS
(left) button until
OFF
mode displays.
4. Remove cover of the master thermostat by gently pulling near one of the
corners at the top of the thermostat.
5. Press the
up
and
down
buttons and
CONFIG
switch simultaneously for 5
seconds.
6. The
OUT
screen displays indicating the master thermostat is ready to
transfer data.
Note:
Press the
up
and
down
buttons and
CONFIG
switch simultaneously for
5 seconds to exit from data transfer mode and to return the master to
the
OFF
mode.
7. Turn off power to the master and remove it from the wall.
8. Connect the master to the target using the 3 wire connector. Attach one
end to the Master’s FP pins and the other end to the Target’s FP pins.
Note:
Target thermostat must be powered with 24 VAC for field programming
to occur.
When the connection has been made correctly, the master thermostat will power up and the target will
count from 5 down to 1. It will then display the
LOCK
confirming the data has been saved in memory.
When all target thermostats have been completed, reinstall the master thermostat.
Press the
up
and
down
buttons and the
CONFIG

Testing the Thermostat
Once the thermostat is configured, it should be thoroughly tested.
Heat Test
1. Press
SYS
(left) button until heat mode is displayed.
2. Adjust the set temperature so it is 5 degrees above the room temperature.
3. Heat should come on within a few seconds. Red LED may turn on.
4. Adjust the set temperature 2 degrees below the room temperature and the
heat should turn off. There may be a fan delay on your system.
Note:
For heat pumps, there is a four-minute delay to protect your compressor after it turns off.
To bypass the compressor time delay, go to
OFF
mode for 5 seconds.
Cool Test
1. Press
SYS
(left) button until cool mode is displayed.
2. Adjust set temperature so it is 5 degrees below room temperature.
3. A/C should come on within a few seconds. Green LED may turn ON.
4. Adjust the set temperature 2 degrees above the room temperature and
the A/C should turn off. There may be a fan delay on your system.
Note:
There is a four-minute time delay to protect the compressor after it turns off.To
bypass the compressor time delay, go to
OFF
mode for 5 seconds.
Fan Test
1. Press
FAN
(right) button. Fan displays. Indoor fan turns ON.
2. Press
FAN
(right) button. Indoor fan turns OFF.
CAUTION
Do not energize the air conditioning system when the outdoor temperature is below 50 degrees.
It can result in equipment damage or personal injury.
Mode of Operation
The Daikin thermostat is an auto changeover, single-stage heat, single-stage cool thermostat. It
functions with air conditioning, heat pumps, gas, oil or electric heat systems.
The thermostat activates the heating appliance when the room temperature is below the set heat
temperature (by the differential temperature) and the red indicator light (configurable) on the
thermostat will light. The thermostat will stop outputting and the red light will turn off when the call for
heat has been satisfied. With heat pumps, the thermostat will not let the compressor come on for 4
minutes after it turns off. This protects your compressor.
When the room temperature is greater than the set cool temperature (by the differential temperature),
the cooling device is activated and the green indicator light (configurable) on the thermostat will
turn on. The thermostat will stop outputting and the green light will turn off when the call for cooling
is satisfied. The thermostat will not let the compressor come on for 4 minutes after it turns off. This
protects your compressor.
The thermostat has four possible operating modes:
OFF
,
Heat
,
Cool
, and
Heat & Cool
mode. In off
mode, the thermostat will not turn on heating or cooling devices.
The manual fan can be turned on in
all operating modes using the fan switch and the fan speed can be set in all operating modes using
the fan speed switch.
In heat mode, the thermostat controls the heating system. In the cool mode, the
thermostat controls the cooling system. In heat & cool mode, the thermostat controls both the heating
and cooling systems. The clock display alternates with the set temperature display for heat & cool
mode.
The thermostat also has a button lockout feature. This enables the thermostat to be set to the proper
mode and temperature and locked so it cannot be tampered with.
