Ener-G-NET features two distinct programming areas: 

User Modes and 

Installer Settings.  User Modes consist of three end-user functional 

modes, while 

Installer Settings are primarily accessed upon initial setup 

to specify critical operating parameters. Ener-G-NET factory defaults 

allow traditional operation suitable for most homes. To optimize the 

control setup, reference the tables below.

Temperature settings above 120° F can create a 

scald hazard.

Domestic hot water setpoint.  Default is 120°F

90-150

Domestic hot water temperature drop before call for heat.  Default is 10°F.

5,10*

Early boiler shutoff prior to hot water setpoint. Circulator runs until setpoint. Default is 0°F.

0,4,8**

Temporarily cancels space heat to maxmize available energy for hot water. Default is 'n'.

y/n

Water heater capacity; select appropriate size for proper operation.  Default is 41 Gallons.

26,41,60,80,120

Real-time BTU transfer estimate in 1000 BTU/Hr increments.  Diagnostic readout only.

0-199MBH/Hr

*Available in Standard Mode only.

**Available only when Differential setting is 10.

Temperature sensor (thermistor) fault.

Sensor unplugged

Sensor damaged

Domestic hot water temperature has exceeded maximum setpoint.

Error in boiler plumbing

Zone valve stuck open

Leak in sensor well

Unit has taken over 60 minutes to reach hot water setpoint or cannot reach setpoint.

Faulty equipment

Fouled heat exchanger

No fuel

Standing water detected.

On-Demand sensing reduces fuel consumption by limiting boiler operation during idle periods.

Traditional operation within preset temperature differential using a low and high limit.

Displayed briefly during intial powerup to test LED display segments.

Reduced temperature setting minimizes boiler operation during anticipaated periods of non-use.

User Modes are used to select from three distinct operational modes.  To select, press the green MODE button and press again to cycle through the three 

available modes.  A green dot illuminates to display the current mode.

Installer Settings are used to adjust functional operating parameters.  To adjust, press and hold the SET button until the Temperature setting appears.  

Cycle through settings by depressing the 

SET button and using the ▼ and ▲ buttons to change the settings.

Diagnostic Error Codes display a visual indicator and sound an alarm if a fault is detected.  Codes clear automatically when corrected or can be reset by 

interrupting power to the control for 5 seconds. To silence an alarm, depress the ▼ on the keypad.

Operating Indicators are used to display operational and functional status. Water sensor temperature may be shown for 30 seconds by pressing 

the ▲ button.

Static numeric [setpoint] readout (factory default shown) indicates domestic hot water setpoint.

Alternating On and [Setpoint] is displayed during a heating cycle while the circulator pump contacts are closed.
