Installation
Installation Location
When choosing the location for the control, consider the following:
• Keep dry. Avoid potential leakage onto the control.
RH ≤ 90% to 104°F (40°C).
Non-condensing environment.
• Avoid contact with water and other liquids; failure to keep
dry may impact control’s operations.
• Do not expose to operating temperatures beyond 32-104°F
(0-40°C)
• Provide adequate ventilation.
• Keep away from equipment, appliances or other sources of
electrical interference.
• Provide easy access for wiring, viewing, and adjusting the
display screen.
• Mount approximately 5 ft. (1.5 m) off the finished floor.
• Locate the control near pumps and/or zone valves if possible.
• Provide a solid backing to mount the enclosure to. For
example: plywood, studs, etc
• Use the conduit knockouts provided on the upper, lower,
back and sides of the enclosure.
Use a Phillips screwdriver to remove
the two screws on the cover.
Pull the front cover towards you. The
top of the cover will pivot on a hinge.
Remove the cover by releasing the
pivot hooks.
Mount the enclosure to a wall using
#6 wood screws in the four mounting
holes. Use screw anchors if drilling
into masonry.
Use the 24 knock-outs to install
connecting conduits and cabling to
the control.
To install the cover, hook the top
of the cover to the enclosure, then
pivot the bottom to shut.
Use a Phillips screwdriver to fasten
the two bottom screws.

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.

• Connect 18 AWG or similar wire to the two terminals provided
in the enclosure and run the wires from the sensor to the
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 (EMI), 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.
• Replace the cover of the sensor enclosure.
• Connect the 2 wires from the outdoor sensor to the Out
Sens terminals on the 294 (terminals 4 and 5).

Mounting the Universal Sensors
These sensors are designed to mount on a pipe or in a
temperature immersion well.
The Universal Sensor should be placed downstream of a pump
or after an elbow or similar fitting. This is especially important if
large diameter pipes are used as the thermal stratification within
the pipe can result in erroneous sensor readings. Proper sensor
location requires that the fluid is thoroughly mixed within the
pipe before it reaches the sensor.
Strapped to Pipe
The Universal Sensor can be strapped directly to the pipe
using the cable tie provided. Insulation should be placed
around the sensor to reduce the effect of air currents on the
sensor measurement.
Immersion Well
If a Universal Sensor is mounted onto 1" diameter L type cop-
per pipe, there is approximately an 8 second delay between a
sudden change in water temperature and the time the sensor
measures the temperature change. This delay increases con-
siderably when mild steel (black iron) pipe is used. In general,
it is recommended that a temperature well be used for steel
pipe of diameter greater than 11⁄4". Temperature wells are also
recommended when large diameter pipes are used and fluid
stratification is present. If the well is not a snug fit on the sen-
sor tube, use the heat transfer paste. Apply paste to the sides
of the sensor and place a pea-sized globule on the sensor tip.
Push the sensor into the well and when it bottoms out, press
firmly. The paste will be forced up the sides of the well.
Conduit Connection
The Universal Sensor and Universal Sensor Enclosure 080
(sold separately) are specifically designed to mount onto a
3⁄8" ID temperature well that is supplied with an end groove.
To install the well, plumb a ‘tee’ into the pipe and fix the well
into the ‘tee’. The 080 enclosure has a 7⁄8" back knockout that
must be removed and fitted over the temperature well. The
Universal Sensor is then inserted into the well and the retaining
clip supplied with the enclosure is snapped onto the well end
groove. If the well has a threaded end, the installer must sup-
ply a standard threaded conduit retaining ring. The two wires
from the sensor are connected to the terminal block provided
in the enclosure. The other side of the terminal block is used to
connect wires from the control.

Testing the Sensor Wiring
A good quality test meter capable of measuring up to 5,000 kΩ
(1 kΩ = 1000 Ω) is required to measure the sensor resistance.
In addition to this, the actual temperature must be measured
with either a good quality digital thermometer, or if a thermom-
eter is not available, a second sensor can be placed alongside
the one to be tested and the readings compared.
First measure the temperature using the thermometer and
then measure the resistance of the sensor at the control.
The wires from the sensor must not be connected to the con-
trol while the test is performed. Using the chart below, estimate
the temperature measured by the sensor. The sensor and
thermometer readings should be close. If the test meter reads
a very high resistance, there may be a broken wire, a poor
wiring connection or a defective sensor. If the resistance is very
low, the wiring may be shorted, there may be moisture in the
sensor or the sensor may be defective. To test for a defective
sensor, measure the resistance directly at the sensor location.
Do not apply voltage to a sensor at any time as damage
to the sensor may result.
Call customer service if you need assistance with technical details.

DHW Call (Terminals 10, 11)
If the DHW sensor option is not used, a call for indirect domestic hot water can come from an aquastat
connected to terminals 10 and 11. The DHW Call can be volt free or up to 24 V (ac).
• Connect the DHW Call terminals 10 and 11 to the DHW tank aquastat.
