Microtech Wall Mounted Sensor - Daikin AVV Installation And Maintenance Manual

MicroTech Wall Mounted Sensor

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 107 and Figure 108). 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.
