Dencor SERIES 200D
The Dencor Demand Computer will SAVE YOU MONEY. You now have a way to make electric rates work FOR you.
Relief from High Bills
It's time for you to start saving! Join the satisfied homeowners already saving 30% to 50% or more on their utility bills. The Demand Computer will prove to be a valuable energy control device for your home. It saves you more money because it's computer provides the most effective load control for Time-of-Use demand and energy rates.
Easy To Operate
You choose the settings and the Demand Computer will do the rest. It takes over the job of lowering your utility bills so you can relax. It remembers to change its operation when the rates change from Summer to Winter, when daylight savings starts and ends or when holidays occur. The Demand Computer can remember your desired monthly demand settings and automatically change the demand each month. If you prefer, it can even take over the task of determining the proper demand level.
Optimum Cooling and Heating
The Demand Computer has many modes of control to provide optimum performance for any home. The selectable MAX-COOL feature provides emphasis on air conditioning for additional comfort. The Demand Computer can even switch the priority of two air conditioners at night. You receive comfort and savings with all types of heating and cooling including heat pumps, air conditioners, baseboard heaters, electric furnaces, electric boilers, and radiant heat.
The Demand Computer has a state of the art electronic battery backed-up memory module which keeps data and time, even for a continuous power outage of up to 10 years. Thirty years of holiday dates are stored.
How It Works
The Demand Computer has two energy control functions:
Only a few major, deferrable loads are controlled - electric heater, air conditioners, water heaters, and the clothes dryer heating element. Controlling these is all that is needed for major savings on your utility bill.
Data Display Station (Model D200)
The Model D200 Data Display Station allows operation of the Demand Computer from a location of your choice. It tells you how much energy you are using and what actions the Demand Computer has taken. The D200 makes changes easy and lets you monitor:
It also provides fingertip control of:
The Data Display Station also provides an audio and visual signal to let you know if uncontrolled loads are creating a demand higher than the set point.
ESS-2 Data Display Station
The ESS-2 is mounted inside the Demand Computer. It provides the same information as the D200 Data Display Station except it does not provide an audio signal when uncontrolled loads are creating a demand higher than the set point. The ESS-2 is used where a convenient display is not needed. It is also ideal for short-term rental units where adjustment by the occupant is not appropriate.
Effective for Time-of-Use Demand and Energy Rates
You can specify independent Summer and Winter control using different on-peak times as well as different forms of control for each season. For each season, control may be specified for:
The following forms of load control are provided:
Wide Range of Applications
The Demand Computer provides you with the control you need for today and the flexibility you need for tomorrow. You will be ready when your utility offers new rates or incentives. It gives a choice of 15-, 30-, or 60-minute demand intervals to fit all utility companies. Control inputs permit future use with utility load management systems.
Selectable Shed Order
You select the priority level of each relay. The Demand Computer can automatically change the priority level from summer to winter or from one part of the day to another if desired.
The Demand Computer keeps a record for the current month and the prior month, of:
Automatic Load Shutdown
The Demand Computer can turn off one or more loads when a specific event, such as a door being open, occurs for a duration of at least 5 minutes. This can help conserve energy.
Easy To Install
The Demand Computer is easy to install.
Simple Utility Rate Selection
A single number will automatically load the parameters of a specific utility rate including:
Power Line Carrier Option
The optional Dencor PLC513 Power Line Carrier Transmitter is an easy way to get to hard to reach places. It uses the existing building wiring to control remote loads or other loads attached to wall outlets, such as waterbed heaters. The PLC513 uses the X-10 Powerhouse code format. It is compatible with receivers sold by Leviton, General Electric, Stanley, Radio Shack, and Heath/Zenith Co.
You will gain additional comfort and savings by preheating or precooling to permit lower energy usage during peak price periods. The power line carrier and thermostat set-back module make this easy.
The Demand Computer is built by Dencor, the nation's most experienced manufacturer of residential Demand Computers. It provides all the features found important in tens of thousands of successful installations.
Conservative design methods provide operation over a wide range of operating conditions. The solid state microelectronic circuitry and industrial quality relays together with a unique RELAY SAVER feature provide extended years of service. Each Demand Computer is performance tested before shipment. Use of components proven by years of field experience has resulted in an extremely reliable energy Demand Computer.
A two-year limited warranty is provided for all parts. Dencor Demand Computers are listed by Underwriters Laboratory and CSA.

Model REM-24 Relay to control remote loads. One SPST relay with 24 Vdc coil and protection diodes. Contacts rated 2 Amperes at 24 Vac for control of Class II circuits. Encapsulated in rubber.
Model PLC513 Power Line Carrier Transmitter Module, 16 selectable house codes, uses key codes 1 through 8
Model AMD466 Appliance Module (3-pin grounded), for controlling an air conditioner, waterbed, etc., anywhere in the home. Rated at 15A for heaters, etc., 1/3 HP for motors, 500W for lamps. No wiring necessary - just plug it in.
Model SRD227 Wall Receptacle Module, replaces an existing wall receptacle. The top outlet is controlled and the bottom outlet is always on. Controls ANY appliance up to 15A. Rated at 1800 watts unrestricted.
Model HDD245 Heavy Duty Appliance Module, 20A for controlling a 220V air conditioners, water heater etc., anywhere in the home. No wiring necessary - just plug it in. For single phase or split phase (110/220V) wiring only. Will not work on 3 phase (120/208V) wiring.
Model UMD506 Universal Module, isolated Class II contacts to switch any low voltage load - electric furnaces, air conditioners etc. Also has a beeper to use as an annunciator. Can be set for momentary or sustained contact closure.
Model THD2807 Thermostat Set-Back, Plugs into an Appliance Module (AMD466) and supplies a small amount of heat under the thermostat when the Appliance Module is turned on. This "fools" the thermostat and causes it to turn heating or air conditioning up or down to precool or preheat the home before peak periods.
