Variable speed blower matched to the Dungs gas valve. Monitored by main controller.
Honeywell gas valve matched to blower motor, controlled by primary controller.
Measures combustion gas temp at discharge vent. Trips at 160°F.
Controls current to anodes for tank corrosion protection. Features LED indicators.
Manages condensation in flue tubes for controlled evacuation to drain.
Provides spark to burner and flame rectification response to controller.
Manages blower, igniter, gas valve. Stores fault history. Attempts ignition.
Color LCD with touch overlay for interface. Displays tank temp & operational state.
Confirms blower motor operation. Normally closed contact.
Monitors water temp and acts as energy cut-off if temp exceeds 200°F.
Detects minimal water presence in bottom pan. Alerts or disables unit.
Maintains controlled flame in combustion chamber for efficient heating.
Wizard guides through initial setup: Time/Date, Hours of Operation, Wifi.
Pressing the 'Enable' button turns the water heater on.
Adjust tank temperature via display arrows or preset 'warm', 'hot', 'very hot'.
Accesses basic settings, configurations, schedules, BACnet, and time/date.
Adjust temp unit, screen lock, alarm beep, EcoNet instance, and elevation.
Control differential temp, pump config, aux input/output, modulation, leak response.
Set specific times for heater to be enabled or disabled daily.
Change current time and date, and configure daylight savings time.
Displays current operating status, diagnostics, sensors, and Wi-Fi status.
Provides product info, alarms, system health, and service alerts.
Connects water heater to home Wi-Fi network for remote access.
View current detected problems and access 'more info' for explanations.
Review previously active alarms and option to clear them.
Check combustion and tank health status via three levels.
Configure frequency for maintenance alerts like drain, vent, and neutralizer checks.
Initial power-up sequence: displays model, temp, status. Checks for heat demand.
Microprocessor runs self-checks, verifies sensors, and initiates blower for pre-purge.
Verifies venting and expels combustion gases before ignition.
Igniter sparks for 2s; gas valve opens, allowing fuel entry.
Confirms flame presence via current. Detects loss or unstable flame.
Heater enters primary heating mode once flame is confirmed.
Cycle completes when set point is reached; gas valve closes.
Blower runs to purge burner and venting system of combustion gases.
Idle state monitoring internal temp and safety devices. Calls for heat if temp drops.
Uses flame rectification via sensor electrode and ground to confirm flame presence.
High limit switch responsive to high water temp, disabling heating functions.
Monitor blower operation and detect blocked inlet/outlet vent conditions.
Detects excessive heat at vent exhaust to protect piping.
Controls automatically resume operation after power interruptions.
Manages multiple ignition attempts before soft or hard lockout.
Evacuates condensation from flue tubes to a floor drain.
