5 Flexible Options for Direct-Venting up to

100 Feet! Placement of units within a building will never be a problem with KNIGHT. It permits up to

100 feet of air intake and

100 feet of exhaust vent with PVC, CPVC, polypropylene or stainless steel pipe. Direct-Vent Vertical Vertical with Sidewall Air Direct-Vent Vertical* Direct-Vent Sidewall* Direct-Vent Sidewall NEW! Compatibility with Copper Fin II Non-Condensing Boiler Allowsyou to create a frontend loading system. NEW! Multiple Sized Boiler Cascade Control KNIGHTS of one or more sizes can be combined into a single cascade to maximize turndown and meet minimum demands. * Internal Cascading Sequencer with Multiple Programmable System Efficiency Optimizers Fine-tune installations using Lead-Lag or Efficiency Optimization Cascade features. * Controls up to Three SetpointTemperatures Allows three different temperature inputs to be controlled. Boiler can be run at the lowest temperature demand for optimal efficiency. * OutdoorResetforEachTempLoop The boiler setpoint temperature responds to changes in outdoor air temperature. Outdoor temperature monitor guides the reset schedule to meet the load. Night Setback Program a heating loop temperature setback for any time of the day, each day of the week. Domestic HotWater Prioritization w/Pump Control On DHW call, SMART SYSTEM overrides the outdoor reset and starts the DHW pump to the indirect water heater alternating to meet both heating and hot water demands. * DHW Night Setback Resets DHW setpoint to save water-heating energy during times of low or no usage. * DHW Max Firing Rate Allows you to limit the maximum percentage of firing rate when in DHW mode. * Separately Adjustable SH/DHW Mode Switching Times Allows controls to be tailored to meet system demand. Design system setup for flexibility. IndirectWater Heater Zone Pump Control All boilers in cascade can be used to meet DHW demand as well as satisfy building load. System &

Boiler Pump Controls Provides power to system and boiler pumps on a call for heat. Programmable post purge allows pumps to operate after a call has been satisfied. Option for Continuous System Pump Operation. * Pump Relay with Freeze Protection Parameters adjustable by installer for flexibility in low-temperature applications. * Installer Access to BMS and Ramp Delay Settings Set up or change these parameters through the control i........
