Place equipment in proper locations. •

Conﬁ gure system piping to connect boiler and HONDA •

MCHP to distribution piping.

Hydronic •

freewatt PLUS

piping conﬁ guration is

modiﬁ ed primary-secondary, allowing heat from MHCP

unit be injected into return piping upstream from

freewatt PLUS

boiler. Conﬁ guration ensures coldest

return water be delivered to MCHP unit’s hydronic

hybrid integration (HI) module.

distribution piping

schematic for system zoned with zone valves for

heating zones and priority pump for indirect water

heater zone. Conﬁ guration of heating zones, boiler

and MCHP heat sources shown is mandatory for proper

operation of
