5.1 Remote Sensor Usage
IMPORTANT!
• The use of spray paint on the sensor housing may damage
the sensor and is not covered by the product warranty.
The remote sensing option is used when an installation
requires mounting the DEH 3000R out of the conditioned
space or when it is desired to specifically monitor and
control the conditions at a particular location in a larger
conditioned space.
Both the need for and location of the remote sensor should
be determined by a heating/cooling professional. In most
installations, the onboard sensor in the DEH 3000R will be
sufficient to monitor and control the conditioned space.
5.2 Install and Wiring Instructions
1. Routing signal wires:
You will be required to supply and route 24 gauge, 4
conductor solid wire (2-line telephone wire) between the
DEH 3000R controller and the remote sensor location. The
wiring run should be no longer than 100 ft. Avoid routing
this interconnect wire parallel to high voltage wiring.
Maintain a distance of 2 ft. or more from high voltage lines.
• Do not run wires longer than 100 ft.
• The use of 24 gauge wire is optimal. Thinner gauge wire
may
limit sensor distance. Thicker gauges will not work with
splice connectors provided.
• Avoid routing parallel to high voltage wiring.
• Maintain a distance of 2 ft. or more from high voltage lines.
2. Sensor connection:
The sensor can be mounted to a wall or ceiling surface.
Ideal sensor location is 5 ft. above the floor. Wires should
exit through a ½” diameter hole in the mounting surface at
the mounting location. Use the provided splice connectors to
connect the 4 wires from the remote sensor to the user-
supplied interconnect wire. Be sure to keep proper colors
attached to each other.
3. Sensor mounting:
Peel the backing from the self-adhesive tape on sensor
housing and stick in place. Apply pressure to insure
permanent placement.
• When installing the sensor, use the “up” marking when
placing the sensor on a vertical wall. This will help keep your
sensor clean and free of dust.
4. Controller connection:
Use the provided splice connectors to connect the 4 wires
from the DEH 3000R to the user-supplied interconnect wire.
Be sure to keep the proper colors attached to each other.
Continue with the installation as described in the rest of this
manual.
