     If this 5 flashes condition continues, replace Electronic Thermostat (ET).
4.  Turn on electrical power at breaker.

E06

6 FLASHES
(Red)

Electronic Thermostat (ET) failure
(Internal processor).

1.  Turn off electrical power at the breaker. Now turn on electrical power to 
     see if error clears. If error has not cleared, replace Electronic Thermo-
     stat (ET).
2.  Turn on electrical power at breaker.

E07

7 FLASHES
(Red)

Lower thermistor sensor failure.

1.  Turn off electrical power at the breaker.
2.  Check electrical connections at Electronic Thermostat (ET).

 Interface 

Module(ESM) failure.

1.  Turn off electrical power.                    
2.  Check wires at the interface module for damage.
3.  If this 8 flashes condition continues, replace module (ESM).
4.  See “Overriding The Interface Module (ESM)” by unplugging from the 
     Electronic Thermostat (ET) on page 12. NOTE: Electronic Thermostat 
     (ET) will continue to be operate, hot water will still be available.

Guard

Electrical Shock Hazard

Do not remove the plactic 

guard from over wiring.

Do not touch electrical wiring.

 

Failure to do so can result in 

death or electrical shock.

IMPORTANT: Before attempting to adjust the ther-
mostat, read the “Water Temperature Regulation” 
section page 10. 

The Electronic Thermostat (ET) is designed so 
that it may control the water heater without the 
Energy Smart

®

 Module (ESM) being operated, 

see page 12.
