Introduction and Overview of the 9312 Congratulations on your decision to purchase the Energy Sentry 9312 Demand Management System. As the owner of a home metered under the Time-Of-Use (TOU) Demand Billing Rate, you fall into a special group of consumers who can lower their monthly electric bills by reducing energy demand peaks and shifting energy usage to Off-Peak times. The Energy Sentry 9312 Demand Management System enables you to reduce these peaks while maintaining efficient use of energy.
or may not be billed for Off-Peak demand. On-Peak times vary from utility to utility; as well as, by season. To benefit from your Energy Sentry 9312 Demand Management System you must have a demand measuring electric meter equipped with the TOU/Demand option and be billed on a TOU Demand Rate from your utility. Obtain a rate booklet or rate sheet from your utility company that describes your electric rate, the KW charges, On-Peak and Off-Peak hours, and how to read your electric meter.
offsets most of the savings on energy costs. Only On-Peak demand is measured and billed under this rate. time, holidays, and up to 4 seasonal On-Peak/Off-Peak time schedules. Case III again uses the same all-electric home billed under the TOU Demand Rate. The energy usage is 3000 Kwh which is the same as Case I and Case II. Let’s assume that 750 Kwh were used in the On-Peak times and 2250 Kwh were used during Off-Peak times.
your lifestyle. These loads usually consist of heating or cooling circuits, dryer heating elements and hot water heaters. These loads represent 60% to 80% of your total connected electrical load. With eight or sixteen separate control points, the 9312 provides maximum utilization of energy. That’s because the loads which are turned on and off are smaller, permitting a more regular and even demand level. This results in greater energy efficiency and comfort.
Figure 2: Control/Display (C/D) Unit System Operation Figure 2 shows the front panel of the C/D Unit. Each indicator and key serves a specific purpose in providing you with the necessary information and control to minimize peak energy usage. Each of these indicators and keys have been numbered and are described below. Mode Display (1): This two-digit indicator displays the 9312’s mode which has been selected to be displayed in the Mode display.
Display Brightness Key (10): This key is used to adjust the display brightness and is used in conjunction with the Decrease key (7) or Increase key (8) to set the display brightness for the best visibility under existing lighting conditions. Alarm Volume Key (11): This key is used with the Decrease key (7) or Increase key (8) to control the alarm volume and allows you to adjust the volume to high, medium, low or off to meet various sound conditions.
1. Press and hold Alarm Volume key (11). 2. Simultaneously press the Decrease key (7) or the Increase key (8). The alarm will come on and beep about 6 times at each volume level. 3. Release keys at the desired volume. Note: If you desire to turn off the alarm, hold down the Alarm Volume key (11) and Decrease key (7) until the alarm stops.
desired comfort level is maintained throughout the home. Minimum On and Off-Times, usually not required under this strategy, may be assigned to each circuit if required. Combination Strategies: Since the 9312 allows the user to program an independent priority for each control point, a virtually unlimited number of combination load control strategies can be selected. One or more groups of rotating loads, with or without fixed priority loads are possible. One combination is shown in Chart B.
Systems Test To verify that the 9312 is measuring demand and shedding 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.
Appendix A — Glossary The following terms are used throughout this manual They are defined here to assist you in understanding their meaning and use. Average Demand: The average rate of electric usage during the demand averaging period. The average demand is calculated by dividing the total number of kilowatt-hours used by the number of hours in the averaging period. For example, if 2 Kwh’s were used during an averaging period of 15 minutes, the average demand would equal 2 divided by .
Appendix B — 9312 Display Settings & Program Sequence Explanation of Main Loop Display Modes Day of Week (do): The current day of the week. 1=Sunday, 2=Monday, 3=Tuesday, 4=Wednesday, 5=Thursday, 6=Friday, 7=Saturday. This applies 9312’s with Version 3.3 or later software. Date (Month & Day) (dA): The current month and day of the month. Setting range from 1/1 to 12/31. Instantaneous Demand (id): The current demand presently being drawn by the electrical service of the home or building.
Saturday/Sunday On/Off Peak (SS): Sets weekends to On-Peak or Off-Peak depending on the local utility’s rate. If your utility has On-Peak periods on weekends, set to “on”. If weekends are Off-Peak, set to “oFF”. Holiday (Hx): where “x” is Holiday 1 through 9. The first four holidays are date-specific holidays or holidays that occur on the same date each year. These holidays are set by date (month and day of month) in any order.

At the Remote Relay Unit, relay leads are wire-nutted to the multi-conductor cable as show in Figure 11. 17.0 System Checkout 17.1 Prior to Test: a. Turn off ALL circuit breakers in the circuit breaker panel. 16.1 Determine the staging sequence of the electric furnace. For example, many furnaces have 3 stages of heat.
b. Place Mode display in the Instantaneous (id) mode. 17.6 c. Restore household loads to the desired condition. The circuit breaker marked “Energy Sentry” or “9312” should be left on with the desired demand limit set into the Control/Display Unit. Turn on a large (greater that 5 KW) uncontrolled load such as the kitchen range. Leave all controlled loads off. Caution: Please take all necessary precautions to prevent damage or injury from the hot surfaces on the stove top.
