The CTRLMax control includes the ability to operate
up to six Prestige Solo boilers together as one without
the need for external controllers. Consult the CTRLMax

The CTRLMax control includes the ability to communi-
cate with building management systems (BMS) through
a Modbus interface. Consult the CTRLMax Control Sup-

Modbus communication will only occur if the external
device is properly wired to the PRESTIGE Excellence as
follows:
X7-1 = RS-485 –
X7-2 = RS-485 Ground
X7-3 = RS-485 +
Triangle Tube has building management system
(BMS) gateways available to convert Modbus to
most BMS protocols including BACnet® MS/TP,
BACnet® /IP, Metasys® N2, and LonWorks®. Con-
