controllers. A BACnet/IP connection is
also possible. For jobs which require an integration
with another BMS,
object points list is required to integrate to the
CORAYVAC
®
Modulating Heating Control into an
existing BMS system to allow for read/write access.
Contact Roberts-Gordon or your local ROBERTS
GORDON

independent distributor for the list of
object points. A foreign BMS will have the ability to
control occupancy, setpoints and more. I/O Pro 812U
has ability to speak to one of the following protocols:
• BACnet over ARC156
• BACnet MS/TP
• BACnet PTP
• BACnet over IP
• BACnet over Ethernet
• Modbus
• N2
• LonWorks

5.4 Communications Between Multiple
CORAYVAC
®
Modulating Heating Controls
If more than one CORAYVAC
®
Modulating Heating
Control is installed in a building, the controllers' MS/
TP communications must be wired in series.
. Connect the MS/TP (Port 1) ter-
minal on controller #1 to the MS/TP (Port 1) terminal
on controller #2 and so on in a daisy chain (
) fashion. Shield wires for MS/TP cables
should be twisted together, but not grounded, at all
satellite controllers in daisy chain. Ground shield wire
at central panel only.
Maximum of 31 controllers to 1 central controller. For
communication cable requirements,
. A MAC address is required for each
central and satellite controller using the "Rotary
Switches"
. There are 2 rotary
switches.
The upper rotary switch is labeled "1's" and lower
rotary switch is labeled "10's". To set the MAC
address for the first 9 controllers, the lower rotary
switch (10's) is set to "0", the upper rotary switch (1's)
is set to the appropriate controller number. To set the
MAC address for controller numbers 10 and up, the
setting of the lower rotary switch (10's) must be com-
bined with the value of the upper rotary switch (1's).
For example: To set the MAC address to "10", adjust
the lower rotary switch (10's) to "1" and adjust the
upper rotary switch (1's) to "0".
Note:
All central controllers should be set to "1". All
controllers should have a unique number assigned
using the rotary switch dials. Changes to the rotary
switches are acknowledged only after the board has
been power cycled.
Contact Roberts-Gordon LLC or your ROBERTS

independent distributor, if more than 31
controllers are required.
