Installation
The Multiple Outdoor Sensor module
is designed to mount in the Outdoor
Sensor enclosure (provided with
Basic and Advanced Heating
Controls) as shown in the diagram.
Remove the screw from the center of
the Outdoor Sensor and pull the front
cover off the enclosure.
The Multiple Outdoor Sensor module
is mounted into the Outdoor Sensor
enclosure. Using the two screws
provided, fasten the module in the
top right hand corner of the Outdoor
Sensor enclosure as indicated at
right.
Connect two conductor 18 AWG or
similar wire between the terminals
S1 and S1 and the outdoor sensor
terminals on one Heating Control.
Do not run the wires parallel to
telephone or power cables. If the
sensor wires are located in an area
with strong sources of
electromagnetic interference,
shielded cable or twisted pair should
be used or the wires can be run in a
grounded metal conduit. If using
shielded cable, the shield wire should
be connected to the Com terminal on
the control and not to earth ground.
Follow the sensor testing instructions
below and connect the wires to the
control.
Repeat the above steps for the
second (S2 and S2) and third
(S3 and S3) sensors.
Features
The Multiple Outdoor Sensor module
includes three 10kΩ thermistors
which provide an accurate
measurement of outdoor
temperature. Each sensor has two
terminals for wiring. The module is
attached inside the outdoor sensor
enclosure included with the control,
and allows for four separate sensors
to be combined into a single
enclosure mounted on the exterior of
the building.
