Page 3: Multi-Mod Platinum Overview
MulTI-MOD PlATINuM OVeRVIeW The Multi-MOD Platinum is a multi-boiler modulating control . It uses PID logic in addition to overlapping the lead and lag boiler modulation, its patent logic, to achieve a smooth modulation and efficient system performance . It is capable of modulating 4 on board boilers . When used with extensions panels it can connect to a total of 20 modulating boilers . -
Page 4: Optional Features
. See "Space Feedback Concept" on page 6 . MODulATION CONCePT The Multi-MOD Platinum modulates the boilers to achieve the smoothest operation and highest system MODULATING CONCEPT efficiency . It does that by overlapping the lead and lag boiler operation . The concept depends on the Ignition % and the Modulation Start % . -
