Installation Instructions

In addition to the following instructions, refer to the
boiler's current Installation and Operating Instructions
manual as well as the V-10 Touchscreen Controller
manual.
Note
The touchscreen controller has new features
including electrical connections that differ from
the 5 button controller (see the Electrical
Ladder diagram on the back page).

controller before beginning the replacement. For
example, record settings in the Installer Setup
menu, Multi-boiler menu, and Load Pairing.
2. Turn off the power to the boiler.
3. Remove the boiler’s main door.
4. Remove the controller’s right side electrical
terminal block cover.
5. From the right side of the IBC board, unplug the

2. Remove the boiler’s main door.
3. Remove the controller’s right side electrical
terminal block cover.
4. Unplug the P/V terminal strip and the two low
voltage terminal strips. If connected, also
unplug the Alarm terminal.
5. Swing out the controller to access the back
side connections.

Installing the new
touchscreen controller
Caution
Since static electricity can damage the
electronic components on the boiler controller
avoid touching the electronics.
If the boiler has a controller mounted on a swing-out
door, you will need to swap the controller's mounting
plate with the one attached to the controller being
replaced.

Swapping the controller's mounting
plate (if required)
1. Remove the front cover from the control board (4
Phillips screws).
2. Remove the five Phillips screws (see Figure 2).
You will need to do this for both boards, starting
with the old controller first.

3. Carefully lift the controls off the mounting plates.
4. Place the screen control onto the swing out door
style control mounting plate, and reinstall the 5
screws. The screws should not be over tightened.

5. For swing-out style controllers:
a. Install the controller by inserting the swing-
out back-plate pivot tabs into the
corresponding holes in the controller's
connections box, upper tab first.
b. Plug the four connectors into the back of the
board.
6. For older IBC boiler models:
a. Remove the front cover from the new
controller.
b. Support the board as you plug the four
connectors into the back of the board.
c. Screw the back-plate of the controller to the
cabinet of the boiler using the four Phillips
screws previously removed with the old
controller.
d. Replace the new front cover of the
controller.
Wiring the touchscreen
controller
If replacing a touchscreen controller board, the field
wiring terminal strips can plug into the new control board
without moving the wires over to the new terminal strips.
When moving the wires from the old green and orange
terminal strips to the new terminal strip, either move the
wires over one at a time or label all the wires as you
disconnect them from the old terminal strip so that they
are not mixed up during transition to the new
touchscreen controller.

1. Using a flat blade screw driver, move the line and
neutral wires from the green terminal block to the
corresponding position on the upper terminal block
for the new controller.
2. Move the wires from the orange terminal block to
the corresponding positions on the low voltage
terminal block on the new controller.
Note
The new controller requires the Therm. 1,
2, 3 or 4 connections to be wired slightly
differently from the way in which the old
controller was wired. See the Electrical
Ladder wiring diagram on the back page.
3. Check that the high voltage terminals are not
wired into the low voltage wiring block.
4. Replace the electrical cover on the right side of
the controller.
5. Restore power to the boiler and replace the
boiler’s main door.
The new controller takes 90 seconds to come on
line.
6. If you are replacing a 5 button controller, place the
new Electrical Ladder Diagram sticker on the
inside of the boiler's main door.
