MicroTech 4 Field Installed Sensors

The MicroTech 4 unit controller can be connected to a variety

of field installed sensors.

• Space Sensor with tenant override – Daikin PN:

113117701

• DDC Space Sensor with Setpoint Adjust and Tenant

Override – Daikin PN: 910143408

• Combo DDC Temp and Humidity Sensor with Setpoint Adj

and Tnt Ovrd – Daikin PN: 910191961

• Communicating Network Space Sensors – Daikin PN:

910279216 and 910278050

• Space Humidity Sensor – Daikin PN: 910202119
• Wall Mounted CO

• Duct Mounted CO

Sensor – Daikin PN: 910111672

Space Temperature Sensors

The Rebel Applied MicroTech 4 works with 10kohm Type 2

thermistors and can support up to 3 sensors. These sensors

can drive cooling and heating based on the highest, lowest, or

average space sensor reading.

DDC Space Sensors

The Rebel Applied MicroTech 4 works with 10kohm Type 2

thermistors and can support up to 3 sensors. These sensors

can drive cooling and heating based on the highest, lowest,

or average space sensor reading. A Combo sensor version

provides Temperature and humidity.

NOTE:

Only one sensor can drive the Setpoint adjustment.

Figure 132: Daikin Space Sensor

Communicating Network Space Sensors

The MicroTech 4 unit controller can be connected to a Network

of the 3 space sensors as either a temperature sensor only

or a temeprature, Humidity and CO

combo sensor. Each

Sensor comes with a backlit LCD screen to show current

space conditions, allow setpoint adjustment and commupance

commands.

• Network Temperature Sensor – Part Number 910279216
• Network Combo Temeprature Sensor – Part Number

910278050

Figure 133: Network Space Sensor

The MicroTech 4 can support up to 3 Network (QMX) sensors

wired to the Process Bus terminals with a Daisy Chain Twisted

pair. Refer to

OM 1288

for MicroTech 4 configuration and set-

up instructions

NOTE:

The sensor is available in English units only and does

not show SI units.
