Lochinvar Corp.: Water Heater, Boiler Control
July 26, 2010
The re-engineered Smart System user interface provides installers and facility managers easier access to all of the information they need to set up, troubleshoot, and monitor all equipment functions. The interface is now standard on all Knight® residential heating boiler models, Knight XL commercial boiler, and Armor® commercial water heaters. The control features a larger display screen to clearly communicate more information. The interface displays a blue screen during normal system operation, while a yellow screen signals that maintenance is due, and a red screen notifies the user that the appliance is in lockout mode. The enhanced control features a built-in cascading sequencer that allows up to eight boilers or water heaters to be installed, providing soft start lead-lag cascade operation. The upgraded user interface also offers the additional option of efficiency-optimized cascade operation, providing the user with two selectable functions for fine-tuning the sequencing of multiple unit installations. The control now offers two-way communication through Modbus protocol. This new capability simplifies the interface between the building management system (BMS) and the boiler or water heater, while allowing the BMS to monitor up to 40 unit variables.
