Wiring Instructions
This section explains how to wire individual devices to the Smart Steam Control 289 . Please refer to technical data table on pg 36
for sensors that are included in the standard packaging of the Smart Steam Control 289 .
Pressure Sensor 089 (Terminals 1, 2, 3)
An optional Pressure Sensor 089 (sold separately) can connect to the 289 to provide staging
for a second steam boiler and to monitor steam pressure up to 15 psi (104 kPa) . The pressure
sensor requires the installation of the following on the steam riser pipe:
• Tee with a ¼"-18 NPT port
• ¼" brass pigtail
• ¼" x
⁄
" reducing elbow

8
Thread the 089 into the reducer coupling . The pigtail protects the sensor diaphragm from
premature failure .
• Connect the Red reference voltage wire to terminal 1 .
• Connect the Green pressure signal wire to terminal 2 .
• Connect the Black power common wire to terminal 3 .
The Pressure Sensor 089 must be installed downstream of a ¼" steam gauge siphon (pigtail)
to prevent premature failure .
Outdoor Sensor 070 (Terminals 4, 5)
• The 070 can be mounted directly onto a wall with the
wiring entering through the back or bottom of the enclosure .
Do not mount the 070 with the conduit knockout facing
upwards as rain could enter the enclosure and damage
the sensor .
• In order to prevent heat transmitted through the wall from
affecting the sensor reading, it may be necessary to install
an insulating barrier behind the enclosure .
Remove
cover by
sliding
upwards
away from
the base.
If using
conduit,
remove the
flexible plug
from the base
bottom.
• The 070 should be mounted on a wall which best represents
the heat load on the building (a northern wall for most buildings
and a southern facing wall for buildings with large south
facing glass areas) . The 070 should not be exposed to heat
sources such as ventilation or window openings .
• The 070 should be installed at an elevation above the
ground that will prevent accidental damage or tampering .
To wire from
the back,
remove the
knock-out in
the sensor
base.
Attach the
base to
the wall,
soffit or
electrical
box.
