limited, so please review the

Stand Alone Boilers Controlled by a Third Party Control
If the boilers are not set up to be lead/lag outdoor reset, a third party control can land the boilers’
connection to J3, MB1 on the Sola control. If this is known at the time the boiler order is entered,
the control will be set up for this type of control. Please refer to electrical diagram in manual for J3,
MB1 connections. The communication wires can be daisy chained to each boiler.

Gateways
Fulton offers (as an option) a Modbus to Bacnet gateway. The gateway will come pre-programmed
and wired in one, or if desired, all of the boilers. If the boilers are daisy chained together through J3,
MB1, one gateway can be used on the master boiler which will be wired to communication port 2 of
the master display. Please refer to

and set-up instructions.
Note: Although there are many points that are available through Modbus, not all of them should be
considered to be continuously written to, all writes should be on a change only. There are specific
write addresses that will fill an internal Sola control EEPROM that should not be continuously written
to. Also all the information out of the control is in Celsius; this may have to be converted to
Fahrenheit if desired. Firing rate also requires a conversion.
