Controls on the Pennant line of fan-assisted, modular gas boilers and volume water heaters from Laars have been updated. The new LINCTM Intuitive Control System includes an auto cascade setup feature for up to eight boilers. A colour touchscreen displays key boiler performance measurements and control structure. It connects to building automation systems via BacNet. There are seven sizes from 500 to 2000 MBH delivering up to 85 percent efficiency, with stage firing of up to 4:1, and cascade with auto redundancy.
