Leaving Coil Temperature Sensor
This sensor needs to be installed downstream of the
cooling coil but upstream of the heating coil on units with
dehumidification that have either modulating cooling valves
or 2/4 compressor stages. A 1/2'' hole needs to be field drilled
in the endplate to install the included plug for mounting the
sensor.

Installation
• Two field provided duct pressure taps will be required
to install this sensor. Locate one tap in the ductwork
upstream of the fan and the second downstream of the
fan.
• Mount sensor on the entering are duct near the location
selected for the duct pressure. See
• Connect the field provided tube between the down stream
port and the high pressure (H) port on the sensor, and
between the up stream tap to the low pressure (L) port on
the sensor.
• Run the wires from the sensor location to the unit.
• Connect the first wire from the Normally Open terminal on
the sensor to TB4-T6. Connect the second wire from the
Common terminal on the sensor to TB4-Common.
