Installation manual

Peak kW Demand (pd): In this mode the kW Demand/Time display will indicate the

highest actual average Peak Demand-since-reset. This indicator is intended to allow

you to monitor your daily or weekly peaks in order to gain an understanding of how

and when these peaks occur. In this way, energy use patterns may be modied, if

desired, to minimize these peaks. It should be noted that if this indicator is reset only

when the utility meter is reset, the peak values should be approximately the same as

the reading on the meter. A difference between the utility meter peak and Peak kW

Demand may occur, however, due to different average demand intervals used by the

utility, varying line voltages, power outages, measurement accuracy and other factors.

The utility meter will be the indication used in determining your electric bill Demand

charge. The Peak light will be on when in the Peak kW Demand mode.

Demand Limit (dl): In this mode the kW Demand/Time display will show the current

home demand limit set point. The function is adjustable using the demand limit

key and the decrease increase keys. The demand limit in the home may have to be

adjusted due to the weather or life style.

Clock (cl): In this mode the kW Demand/Time display will show the current time.

This time may be up to an hour fast or an hour slow due to time changes. Do not

set the current time due to the time is set to the meter if you believe the time is not

correct please give BHP a call and we will assist you with any questions.

A.M. P.M. LED will only be present when the demand controller is in the clock mode.

Reduce Load: The “Reduce Load” indicator will come on and the alarm buzzer will

sound when all controlled loads have been turned off, but actual demand is still

above the limit. When this occurs, you may either reduce uncontrolled demand,

increase the limit if needed, or turn the buzzer off. By turning the buzzer off, you may

exceed the demand setting on your controller.

Circuits On: These indicators, when lit, tell you which control circuits are on. A

“Circuits On” indication does not necessarily mean that the controlled load is on, but

rather the load is free to go on if the thermostat calls for it.

Decrease Key: This key operates in conjunction with the Demand Limit key (10),

Display Bright key (11), and the Buzzer Volume key (12) and is used to decrease the

functions controlled by these keys.

Increase Key: This key operates in conjunction with the Demand Limit key (10),

Display Bright key (11), and the Buzzer Volume key (12) and is used to increase the

functions controlled by these keys.

Demand Limit Key: This key is used to set the demand limit and is used in

conjunction with the Decrease key (8) or Increase key (9) and allows you to adjust

the demand limit up or down to the level which best suits your particular energy

requirements.
