ROOM CONTROLS (continued)
3. T100 CONTROL INSTALLATION The low voltage control T100s can be mounted directly to a
fi
nished
wall. Connect the control to the interface using the 25 foot (7.6 m) shielded 8 conductor cable (provided).
String the cable from the control location through
1
/
2
” (13 mm) holes in the wall studs or ceiling joists to the
interface. Note:
Do not staple through or damage cable. Use factory supplied cables only.
In the steam room: A mounting template is included at the end of this document. Using the supplied tem-
plate, cut a hole in the
fi
nished wall where the control is to be mounted and pull the cable end out through
the mounting hole. Plug the control cable into the cable on the back of the T100 control housing. Run a
bead of 100% silicone caulk around the perimeter on the back of the control housing and insert the T100
into the
fi
nished wall, center the control and tape the control against the
fi
nished wall while the silicone
hardens.
At the interface box: Connect the control cable’s plug into the T100 jack on the box’s circuit board. Orient the cable end
to match its socket and insert it until the end locks in place. Use a cable strain relief (provided) to secure the cable to the
interface box.
4. CONNECT BOILER A 25 foot (7.6 m) three conductor cable is provided to connect the interface box to the AI boiler steam
boiler. String the cable from the control location through
1
/
2
” (13 mm) holes in the wall studs or ceiling joists to the interface.
Note:
Do not staple through or damage cable.
Install the cable in the interface’s BOILER T’STAT terminal block by press-
ing the orange tab, inserting the stripped end of one cable conductor, then releasing the tab. Repeat until all three wires are
secured. Repeat the process to connect the other end of the cable to the boiler circuit board’s T’STAT terminal block.
Be sure
the position 1 at the interface connects to position 1 at the boiler, 2 to 2 and 3 to 3!
Use a cable strain relief (provided)
to secure the cable to the interface box.
5. INSTALL BYPASS The T100 connects to its own temperature sensor through the interface so the normal boiler tempera-
ture sensor is not connected. Instead, a sensor bypass (supplied) must be plugged into the TEMP SENS jack on the boiler’s
circuit board as shown at right. Orient the bypass plug to match the jack and insert it until the end locks in place.
6. CONNECT INTERFACE POWER A power converter provides low voltage to the interface for normal operation.
Connect the power converter into an outlet near the interface box then run its cord through a hole in the interface
box and connect it to the power jack on the interface circuit board (between the T-STAT terminal block and the
T100 jack). When power is connected, the PWR light (
above the T’STAT terminal block
) should light bright and
steady. Use a cable strain relief (provided) to secure the cable to the interface box.
7. LIGHT (OPTION) The interface circuit board includes a terminal block for use with a low voltage room light, such as
Amerec’s Chormatherapy kit (
contact Support for more information
). Connect the interface in line with one of the light’s
power leads as shown at right and connect those leads to the LOW VOLTAGE RM LIGHT terminal block by pressing an
orange tab, inserting the stripped end of a conductor, then releasing the tab. After connecting both wires, use a cable strain
relief (provided) to secure the light wires to the interface box.
8. BOILER SET UP Place or remove jumpers on the boiler’s circuit board as shown in the drawing on the next page.
STARTING THE BOILER FOR THE FIRST TIME
Before applying power to the boiler for the
fi
rst time: On the electrical box’s front panel, set all rocker switches to the left,
their normal operating position. If installed, set the optional Run Clock so the boiler is off and make sure the water supply is
connected to the boiler and turned on.
• Open the valves on the glass water gage all the way (counterclockwise).
• Open the pressure gage valve (handle horizontal). or
• If the Autodrain option is not installed, close the manual drain ball (handle up).
• If the optional electronic Autodrain is installed, open the manual drain ball valve as shown (handle pointing
towards electronic valve). Set the Drain Clock to an off position (no orange showing in area above pointer).
• Turn on the electrical service to the boiler. All lights and valves should be off at this point.
