Systems Test
To verify that the 9312 is measuring demand and shed-
ding loads properly, make the following test:
1. Turn off all household loads or as many as possible.
Leave the 9312 on. Note level of Instantaneous demand.
Make sure it is less than 2 KW.
2. Set the demand limit (dL) to 2 KW.
3. Look at the back of this manual or on the part of the
C/D United labeled Circuit Assignment to verify the number
of loads you have connected to your 9312. Whatever number
of loads you have connected, make sure that same number
of LED indicators are lit in red in the Circuit On Display.
Turn on oven and all top elements of your stove. Please
take all necessary precautions to prevent damage or injury
from the hot surfaces on the stove top. Do not leave elements
on more than the brief amount of time it takes to run this test.
4. The system will shed (turn off) all controlled loads.
This can be observed by watching the LED indicators
on the right side of the display. This may take just a few
minutes. The A/C may take longer to turn off if the unit is
programmed with a Minimum On-Time (maximum time
will be 20 minutes).
5. When all available loads have shed, the alarm will
sound indicating that your demand is still above 2 KW
because the stove and oven are still on. Turn off all stove
elements and oven. Once all loads have shed, the Instanta-
neous demand display (id) should drop to near zero.
6. Raise the demand limit (dL) to the maximum demand
setting. (Leave the demand limit at this level only long enough
to complete this test as a high peak demand may occur.)
7. Return the demand limit to your normal demand
setting once you see the loads beginning to restore.
8. All loads will restore according to the control
strategy and when Minimum Off-Times have elapsed (it
may take the A/C up to 20 minutes). This can be observed
by watching the enabled LED indicators. Instantaneous
demand will increase as each load is restored. If all steps
are completed, the 9312 is working properly.
Hints for Maximum
Savings
When the demand limit setting is to be decreased (i.e.
from 10 KW to 8 KW), the setting should be decreased
BEFORE your utility meter is read. In addition, when the
demand setting is to be increased (i.e. from 6 KW to 7
KW), the setting should be increased AFTER your utility
meter is read. Check past bills or call the utility company
directly to determine this date.
You can help increase the effectiveness of your 9312
by trying to avoid turning on two or more major appliances
at the same time (i.e. dry clothes at times when the range is
not in use). This will assist the 9312 in controlling demand
and it will increase the comfort level of your home.
Shifting use of all loads possible to Off-Peak times
will help to reduce your On-Peak energy usage charge
and increase your savings. In most TOU Demand Rates,
the On-Peak demand and energy charges are substantially
more costly than the Off-Peak charges. Consult your utility
to determine your On and Off-Peak times.
Service of Heating/Air
Conditioning, Water
Heater & Clothes Dryer
When technicians service any electrical equipment
that is controlled by the 9312, they should be advised that
you have a demand management system. They should
also be warned NOT to disconnect the 9312 wiring or
its circuit breaker off. Otherwise, they may disable your
9312 which could result in a very high electric bill.
If
your 9312 is turned off by service technicians, avoid using
heating/cooling systems, the dryer and water heater until
power to the demand management system is restored.
The Energy Sentry 9312 cannot cause damage or pre-
mature failure of the equipment when it is installed and set
correctly. Nor can it cause a higher electric bill than you
would have had without a demand management system.
When the power to the 9312 is off at the circuit breaker
panel, power will be available to all controlled loads. Without
power, the 9312 cannot control your demand. This is why
the power must be restored to the 9312 after a service call.
If You Need Service
Your Energy Sentry 9312 has been carefully assem-
bled 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 9312 has been designed so household appliances
and loads 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 9312 at the circuit breaker labeled “9312” or
“Energy Sentry,” located in the circuit 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 appropriately only while you
are in each room.
2. When cooking meals, all heating or cooling zones,
as well as the water heater and dryer should be turned off.
3. Avoid using appliances simultaneously. For
example, do not use the dryer, water heater and range at
the same time.
4. You may monitor your highest demand peak on
the utility meter to determine the effectiveness of manual
control.
5. Since there are no user serviceable parts or compo-
nents in the 9312, refer all service to the authorized Energy
Sentry dealer as described in the Warranty. You can log on
