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
1
⁄8" reducing elbow
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.
• 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.
