ENVI® Boiler Control System
ENVI® Boiler Control System
Designed to maximize efficiency, our ENVI® outdoor boiler control system monitors and modulates the combustion and ignition of the boiler to maintain the desired outlet temperature.
This flexible boiler control system can run a single boiler or a master/member network of up to 16 boilers. The lead/lag setup and boiler start rotation ensure run times are equally distributed across each unit in the system, extending the life of the boilers.
The ENVI® boiler control is an on-board control system, eliminating the need for external control panels and reducing ancillary component costs. Control both condensing and non-condensing boilers in a hybrid system for maximum efficiency at minimum cost.
