Field Setting - Daikin FTQ18TAVJUA Installation Manual

Wire specification Sheathed vinyl cord or cable (2 wires)
Gauge AWG18 - 16
Length Max. 328 ft.
Contact that can ensure the minimum
External terminal
applicable load of 16 V DC, 1mA.
8.8 FIRE ALARM SWITCH
The control is equipped with two Fire Alarm terminals, labeled
T1 and T2 which are typically utilized in series. The fire alarm
switch must be normally closed and open when the alarm occurs.
For example, a normally closed fire alarm switch will open when
the CO2 reaches a particular level. The control will respond by
turning off whole system (all indoor units and outdoor unit) and
displaying the proper fault codes.
(The switch is closed as part of the default factory setting.) The
error will be maintained in the equipment's fault history. See
picture (Figure 23) for the connection location.
Refer to Table 5 for fire alarm setting.
8.9 AUXILIARY ALARM SWITCH
The control is equipped with two Auxiliary Alarm terminals,
labeled TB4 and TB5 (2VA or less) which are typically utilized in
series with a condensate switch.
The auxiliary alarm switch must be normally closed and open
when the alarm occurs. For example, a normally closed
condensate switch will open when the base pan's water level
reaches a particular level. The control will respond by turning off
the blower motor and outdoor unit and displaying the proper
fault codes.
If the switch is later detected closed for 30 seconds, normal
operation resumes and the error message is removed. (The
switch is closed as part of the default factory setting.) The error
will be maintained in the equipment's fault history.
See Figure 28.

2. Depending on the type of installation, make the field settings
from the remote controller after the power is turned on,
following the "Field Settings" manual which came with the
remote controller.
• The settings can select "Mode No.", "FIRST CODE NO." and
"SECOND CODE NO.".
• Field settings are normally applied to the entire remote control
group, however if individual indoor units in the remote control
group require specific settings or for confirmation that settings
have been established, utilize the "Mode No." in parenthesis.
• The "Field Settings" included with the remote controller lists
the order of the settings and method of operation.
• Make sure the customer keeps the "Field Settings" manual,
along with the operating manual, in a safe place.
9.1 SETTINGS WHEN USING THE OPTIONAL
REMOTE SENSOR
This product does not include an air inlet thermistor. It uses a
remote controller thermistor for control purposes. For this reason,
it is necessary to install an optional remote sensor in the following
cases:
• When the remote controller will be installed at a location
where it cannot accurately measure the indoor temperature.
• When using a remote controller without a built-in thermistor
(simple remote controller, wireless remote controller, no
remote controller).
When using an optional remote sensor, change the settings
as described Table 3:
