2.7 MCM10 Multi Cascade Module

The MCM10 - Multi Cascade Module allows running and
staging multiple boilers in a cascade system.
Each MCM10 controls up to 4 boilers, and with 4 modules in a
system, up to 16 boilers can be controlled.
The MCM10 can only be used with boilers that have the EMS-
BUS (UBA3, UBA3.5).
Boilers of any size can be connected in the cascade system as
long as they are EMS-BUS compatible.
2.7.1 System Integration
The MCM10 stages the boilers within the cascade system
based on a heat demand from one of the following the following
sources:
• 0-10V BMS input directly to the MCM10
• W-A dry contact input directly to the MCM10
• AM10 outdoor reset controller with dry contact input
• RC35 energy management system
The MCM10 controls the system supply temperature, which
requires a system supply temperature sensor strategically
placed.
