About this guide
This quick start guide provides the basic information you need to
configure and install the Boiler Controller and application.
For further information, refer to the Verasys® 32 Point 24 VAC
Application Controller Installation Instructions (24-10143-01515), and
Verasys Boiler Controller Application Note (LIT-12013275) on
QuickLit.

Mounting the controller
To mount the controller, complete the following steps:
1. Mount a 20 cm (8 in.) section of
35 mm (1.3 in.)DIN rail
horizontally.
Note: Mount the controller in the horizontal position.
2. On the back of the controller, extend the two mounting clips as
shown in the following figure.
3. Place the controller on the DIN rail.
4. To secure the controller on the DIN rail, push the bottom
mounting clips up as shown in the following figure.
5. To remove the controller from the DIN rail, pull the bottom
mounting clips out to the extended position and carefully lift the
controller off the DIN rail

Wiring the controller
The system bus terminal block is a blue, removable, 4-terminal plug
that fits into a board-mounted jack. To wire the controller, complete
the following steps:
1. Wire the removable system bus terminal block as shown in
Figure .
2. Wire any other devices that you want to connect on the system
bus in a daisy-chain configuration using 3-wire twisted, shielded
cable as shown in Figure 5.
Figure 4: System bus terminal block wiring
Figure 5: Daisy-chain wiring configuration
Enable the end of line (EOL) switch
If the controller is at the beginning or end of the line on the system
communication bus, you must activate the EOL switch.
1. To disengage and remove the plastic cover press down on the top
of the controller.
Note: Ensure that you do not disconnect the ribbon cable that
connects the controller to the board display.
Note: The EOL switch is a red block with a white switch located
directly above the system bus terminal block.
2. Turn the EOL switch on by moving the white switch to the right.
Wiring the supply power terminal block
The 24 VAC supply power terminal block is a gray, removable,3-
terminalplugthatfitsintoa board-mounted jack on the top right of the
controller.
Wirethe 24 VACsupply powerwiresfrom the transformer to the HOT
and COM terminals on the terminal plug, as shown in Figure 6.
Note: Do not use the middle terminal on the supply power
terminal block.
Note: The supply power wire colors may be different on
transformers from other manufacturers. Refer to the transformer
manufacturer’s instructions and the project installation drawings for
wiring details.
Figure 6: Supply power terminal block wiring
Wiring options
Configurable outputs 1, 2, and 3, and triac binary outputs 8 and 9 are
rated for a maximum current draw of 0.5 A. It is best practice to use
pilot relays when you use these outputs to drive contactors.
You can choose a pilot relay with a manual override function. You can
also use software to reverse the polarity of the output. This means
that you can drive contactors with contacts that are normally open
(fail off) or normally closed (fail on).
