Service of Heating/Air Conditioning,
Water Heater and Clothes Dryer
When technicians service any electrical equipment that is controlled by the controller,
they should be advised that you have a demand controller. They should also be warned
not to disconnect the controller wiring or leave its power supply (circuit breaker) off.
Otherwise, they may unknowingly disable your controller which could result in a very high
electric bill. Damage could result to your controller or air conditioner by incorrect rewiring
of your controller’s remote air conditioner or heat pump relays. The Energy Sentry demand
controller simply acts as another switch on the water heater, dryer, or heating/cooling
equipment. It cannot cause damage or premature failure of the equipment it is connected
to when it is installed and set correctly. Nor can it cause a higher electric bill than you
would have had without a controller.
When the power to the control unit is off at the breaker panel, power will be available to all
controlled loads. Without power, the control unit cannot control your demand.
The power must be restored to the controller. Contact BHP to check your meter to assure
your demand did not exceed the set point while the control unit was off.
If You Need Service
Your Energy Sentry demand controller has been carefully assembled and tested at the
factory. Only components having a high degree of reliability and long life have been used
in its manufacture. In the event that a failure does occur, your control unit has been
designed so household appliances will continue to function.
The only difference is that there will be no demand control, and high demand peaks can
occur. If a malfunction should occur, you may turn off the unit at the breaker labeled
“Demand Controller,” located in the load center (breaker panel). You may control your
demand manually, if desired, to avoid unnecessary demand peaks as follows:
1. Heat or cool only those rooms which are occupied by keeping the thermostat
set only while you are in each room.
2. When cooking meals, all heating or cooling zones should be turned off.
3. Avoid using appliances simultaneously.
4. You may monitor your highest demand peak on the utility meter to determine
the effectiveness of manual control.
5. Assure nothing else is connected to the demand controller circuit breaker;
i.e., chest freezer, refrigerator, etc.
