Hints for Maximum Savings
When the setting is to be decreased (for example from 10 in February - for heating - to 8
in March for less heating), the setting should be changed 5 days before your utility meter
is read.
When the setting is to be increased (for example, from 6 in May to 7 in June for air
conditioning), the setting should be changed after your utility meter is read.
Meter readings are taken on various days of the month and depend on the billing interval
you happen to be on with BHP. You can check past bills to determine this date, or call BHP
directly. To help you set your demand limit based on appliance load, see Page 12 - Table
2: Typical Residential Appliance Ratings or contact your local BHP ofce.
You can help greatly in increasing the effectiveness of your unit, and may increase your
savings, by trying to avoid turning on two or more major appliances at the same time. For
example, homeowners should try to avoid using the electric range while other appliances
are operating.
Load Shedding Sequence
When your power consumption average starts to approach the demand setting, the
controller sheds the rst load. If necessary, additional loads will be shed to keep the
average demand below the demand setting. Loads are shed according to the priority
strategy selected; either the xed priority strategy, the rotating strategy, or a combination.
See the Installation Manual for an explanation on how to select the load control strategy
or call your local BHP ofce.
The load shedding priority selected is based on the type of heating and cooling equipment
and the design of your house. If desired, the priorities may be easily changed by your
dealer or electrician.
Control of Clothes Dryer
The clothes dryer is usually one of the last circuits the load controller sheds. When the
dryer is shed, the dryer motor continues to tumble clothes. Only the heating element is cut
off during this brief period. This means that when you are set at 5 or 6 kW and cooking a
large meal, the dryer will be shed when the oven element (4.5 kW) is on. When the oven
element is off, the dryer element is restored. This may result in your clothes being slightly
damp at the end of the drying period and may require longer drying times. If your dryer
has a dampness control, BHP recommends using it.
