Installation Manual
Energy Controller
Model EC
PLEASE READ INSTRUCTIONS CAREFULLY BEFORE INSTALLING
The design anticipates the proper installation and care in use of the
product. There is risk of property damage and personal injury inherent in the
use of any hot water system. The Company cannot supervise the installation
and therefore makes it a specific condition of the warranty that the customer will
supervise the installation and use of this product to be sure they are performed
in accordance with safe guidelines and proper local or national codes.
Generalized instructions and procedures cannot anticipate all
situations. For this reason, only qualified installers should perform the
installation. A qualified installer is a person who has licensed training or a
working knowledge of the applicable codes, regulations, tools, equipment and
methods necessary for safe installation of an electrical component on a
residential water heater.
If questions regarding installation arise, check with your local plumbing
and electrical inspectors for proper procedures and codes. Local codes take a
precedent over instructions in this manual.
The energy controller (EC) is basically a timed switch that interrupts
power going to the controlled elements of the water heater based on the control
program. The EC does not control the temperature of the water heater.

Basic installation of Energy Controller
A. INSTALLATION
Shut off power to water heater before installation.
Mount the EC to a junction box using the included lock nut. The junction
box may be on the water heater or wall mounted.
B. WIRING DIAGRAMS
Verify the wiring diagram used matches the wiring of the water heater.
Connect the red and black 18 awg wires to the line power leads.
Connect the red and blue 12 awg wires according to the desired wiring
diagram.
Tighten wire nuts securely.
WARNING: Loose connections in high current circuits may cause fires.
Important:
The wiring diagram being followed must match the wiring of the tank. In the
BIW and #5 diagrams, the wires connected to L1 and L2 must be the wires that
would be connected to L1 and L2 if the EC were not being used.
C. STARTUP
When first powering up the water heater with the EC, press ON to go
into Override Mode to allow immediate heating. The EC will follow the
control program otherwise.
Note: Pressing OFF will put EC into Vacation Mode. This should be
canceled by pressing ON to cancel Vacation Mode. If Override Mode is
desired, press ON again if Override wasn’t already selected.
