Simplicity Creates Versatility

You've heard of "user friendly" computers? ChronTrol could be called "user-protective." Not only does it prompt you through the setting process by displaying the questions and your commands, it also relieves you of worry by

• Automatically adjusting for seasonal shifts of Daylight Saving Time
• Automatically accounting for leap years
• Guarding its time-keeping and program memory in the event of A/C power loss with its own backup battery system. The improved system provides three years of backup power
• Automatically monitoring the backup batteries, and displaying Replace Battery! when needed
• Exhibiting time of last A/C power loss, and cumulative time of single or successive power interruptions
• Not letting you enter invalid times, cycle rates, dates, program numbers, circuit numbers, or any other impossible or conflicting commands
• Protecting itself from unauthorized tampering by use of a keyboard unlocking code, which you can change at will

Simplicity Is The Difference

The purpose of energy management - saving money - is defeated if you have to hire a computer specialist to operate your time control equipment. But with the ChronTrol L Series, your present and future energy management needs are solved, and the tool can be operated by anyone capable of mastering an automated teller machine.

If time is money, then consider ChronTrol a kind of bank that protects your time until you're ready to spend it. Lighting, security systems, industrial machinery, heating and air conditioning - absolutely anything electrical - is placed at your fingertips by this rugged wall-mounted unit.

When it comes to efficient, reliable, and prudent time management, ChronTrol is in control. But you are in command.

Engineered To Save Time, Money, And Headaches

ChronTrol's microprocessor gives you 60 operational programs, each capable of controlling any or all of the available circuits. The programs are set through the uncomplicated twenty-key control panel. Your commands are visually confirmed on the unique 32 character Liquid Crystal Display before they enter ChronTrol's memory.

ChronTrol Expands With You

As your needs grow, so can ChronTrol's capabilities. Our unique four circuit relay modules expand ChronTrol's L6016 model from four to eight to twelve to sixteen independent circuits. Installation is quick and easy, and keeps ChronTrol cost-effective as your time control requirements multiply.

Programming overview

You program ChronTrol by first giving the microprocessor its bearings, which appear as questions on the display:

• TIME OF DAY? ChronTrol's line frequency time base is the most accurate commercial clock available. Time is set to the second, a.m. or p.m.
• MONTH: DAY: YEAR? DAY OF WEEK? Once ChronTrol knows where it is in time, it automatically adjusts for leap years and daylight saving time.
• HOLIDAY LIST? Up to twenty holidays can be accommodated. Each holiday can either be a single day or an unlimited span of days.
• UNLOCK CODE? A user-programmable four-digit number provides fail-safe security.
• CIRCUIT RESTART? Helps avoid damaging power surges by telling ChronTrol the rate at which circuits are to restart after a power interruption.
• NORTH LATITUDE? Lets ChronTrol adjust its programs relative to sunrise and sunset automatically.

Depositing Time In The (Memory) Bank

With just eight steps, any one of a possible 60 programs can by set. These can later be modified, reviewed, or canceled at will. Once programmed, ChronTrol performs its assigned duties with split-second accuracy, and allows for quick-glance monitoring by showing which circuits are in use at any one time. With its technically advanced design, ChronTrol gives you the ability to schedule operations for up to a year in advance. In logical sequence, ChronTrol asks you to set as many of the eight operational parameters as you need for each program.

You start the setting process by pressing the Program key:

• PROGRAM NUMBER?
  Automatically, the first unassigned program number is displayed on the LCD. You have the option of selecting it or any other number (up to 60) that isn't already in use.
• CIRCUIT NUMBERS?
  Used to specify which circuit(s) the program is to control. Each program can control any or all of the available circuits.
• TURN-ON TIME?
  Used to set the time of day (to the second, a.m. or p.m.) at which the assigned circuit(s) goes ON.
• TURN-OFF TIME?
  Used to set the time of day (to the second, a.m. or p.m.) at which the assigned circuit(s) goes OFF.
• SKIP DAYS?
  The day or days you do not want the program to occur are set by pushing the proper day-of-the-week key(s).
• CYCLE RATE?
  This specifies how often you want the Turn-On and Turn-Off times to repeat. If you want them to recur every twenty-four hours, no setting is necessary. Otherwise you may set cycle rates from every two seconds to every one hundred hours.
• DUTY CYCLE ON?  DUTY CYCLE OFF?
  Duty cycling will occur only within the operating window established by a program's Turn-On and Turn-Off times. This helps maximize energy efficiency by turning equipment ON or OFF intermittently during the course of a single program.
