Weil-McLain® has enhanced its high-efficiency SlimFit™ 1,000, 1,500, and 2,000 MBH commercial condensing boiler line with the advanced capabilities of the Unity™ Controller. The company says the upgrade is designed to reduce installation and set-up time for contractors, simplify boiler system design for specifying engineers, and improve control interface commonality and communication across the entire Weil-McLain high efficiency boiler line.
The new control features include a setup wizard that guides the installer through the start-up process and 10 preset typical heating operation conditions. The new design also features zone stacking up to 24 programmable zones without the need for additional external panels and 0-10 VDC analog output signal for integration with a lag boiler in a hybrid system.
