Field Wiring Remote Mounted Temperature

Sensor

The low voltage eld wiring connections have all been centrally located

within the unit ventilator and are easily accessible.

To simplify eld connections, multi-pin plugs are factory provided and

pre-wired with short wire whips (see gure 57). Each of the wires in

these wire whips is capped and should remain capped if not used. The

unit mounted temperature sensor is provided with a quick disconnect

plug (white) with wires numbered 101 and 102, and must be separated

so that the unit mounted sensor is disconnected from the UVC. This

disables the unit mounted sensor (see gure 58). See Figures 59 and 60

for wiring the remote mounted temperature sensor to the unit control

wiring.

Figure 57: Wire whips with Caps for Field Wiring Remote

Mounted Temperature Sensor

All low voltage eld wiring connections must be run in shielded

cable with the shield drain wires connected as shown in the

eld wiring diagrams.

Installing the Remote Mounted Temperature Sensor

This describes the installation of the following three wall mounted

sensor models:

• P/N 111048101 – Basic

• P/N 111048103 – Expanded ± 3

F setting

Use the installation instructions included with the Remote wall

sensor.

Parts Included - All Models

• pre-assembled sensor that includes:

- large (50.8 x 101.6 mm [2 x 4 in.]) mounting base (1)

- terminal block (1)

- 1.5 mm (1/16 in.) cover screw (1)

- end caps (2)

• alternate small (80 x 80 mm [3.15 x 3.15 in.]) mounting

base (1) with attached terminal block (1)

• cover slider insert with printed logo for Daikin (1)

• No. 6-32 x 1 in. at-head screw (2)

• No. 8 x 1.25 in. panhead tapping screw (2)

• hollow plastic wall anchor (2)

Parts Included - 111048103 Only

• alternate serrated setpoint dial (attached)

• smooth setpoint dial (separate)

Special Tools Needed

• .5 mm (1/16 in.) Allen wrench

• 7 mm (1/4 in.) at-blade screwdriver

• hole saw with 35 mm (1-3/8 in.) blade (for surface mounting only)

• drill with 8 mm (5/16 in.) drill bit (for surface mounting only)

The unit comes with a unit mounted sensor and does not require

a remote wall mounted sensor.

BLK

Static sensitive components. A static discharge while handling

electronic circuit boards can cause damage to the components.

Discharge any static electrical charge by touching the bare metal

inside the main control panel before performing any service work.

Never unplug any cables, circuit board terminal blocks, relay

modules, or power plugs while power is applied to the panel.
