The TriMax Boiler Management System is designed to be flexible yet easy to use. TriMax monitors
and controls the Prestige to operate as efficiently as possible. TriMax monitors the boiler supply,
return and flue gas temperatures and operates the igniter, gas valve and blower. TriMax uses this
information to modulate the boiler’s firing rate to maintain the required setpoint.
TriMax offers many advanced control options, which may be adjusted for various applications to
achieve optimum boiler efficiency and operation.
• Two central / space heating (CH) call inputs with separate outdoor reset curves.
• Domestic Hot Water (DHW) call input with optional priority.
• System temperature sensing and control with an optional system temperature sensor.
• Cascade function allows up to six Prestige boilers to operate together in a single heating system.
• Modbus interface for integrating with building management systems.
These advanced features are adjustable in the nstaller Menu after entering an access code.

CH Call Blocking sets the minimum time between burner firings for
central heating calls. At the completion of a burner firing, the CH Call
Blocking time will begin. The burner will not fire again until after the
CH Call Blocking time has elapsed. The CH Call Blocking time only
prevents the burner from firing, the central heating circulators will
respond to a central heating call. This blocking time has no affect on
domestic hot water calls. The CH Call Blocking feature prevents short
cycling of the burner and extends the life of the burner components.
