Microtech Wall Mounted Sensors - Daikin ARQ Installation And Maintenance Manual

MicroTech Wall Mounted Sensors

WARNING
Rigorously adhere to field wiring procedures regarding proper
lockout and tagout of components.
WARNING
To avoid electrical shock, personal injury or death:
1. Installer must be qualified, experienced technician.
2. Disconnect power supply before installation to prevent
electrical shock and damage to equipment.
3. Make all connections in accordance with electrical wiring
diagrams, and in compliance with national and local codes.
Use copper conductors only.
4. Do not exceed ratings of the device. This is a low voltage
device: Never apply more than 12VAC/VDC to any lead or
damage will result.
5. Avoid locations where excessive moisture, corrosive fumes,
or vibrations are present.
Note: Avoid placing wall sensor near drafty areas such as
doors or windows. Avoid external walls, or dead spots
near exposed columns. Avoid direct sunlight on wall
sensor.

When Using A Remote Temperature Sensor
If a decision is made to use a Wall Mounted Temperature
Sensor instead of the unit mounted room air sensor then
placement of the Remote Wall Mounted Temperature Sensor
is critical for proper room temperature sensing (see Figure
52 and Figure 53). The UVC is capable of using one of four
remote wall mounted temperature sensors. It is recommended
that additional wires be pulled to compensate for potential wire
breakage or future options.

NOTICE
All MicroTech equipped unit ventilators are provided as standard
with a unit mounted space temperature sensor. The unit mounted
temperature sensor is provided with a quick disconnect plug (white)
located outside of box with numbered wires 101 and 102.
