INTRODUCTION
The AP22 is a two-circuit, AC or DC (12VDC) powered, calendar programmable solid state time switch used for switching
electric circuits according to a preset time and date program. The AP22 is primarily designed for school zone and traffic
control use where multiple daily/weekly programs are required on an annual basis.
INSTALLATION OVERVIEW
The AP22 may be attached by using the keyhole tab on the back of the enclosure. Two mounting holes on the inside of the
enclosure and below the circuit board are accessible for additional support.
Outdoor use of AP22 requires installation in a NEMA Type-4 cabinet. Indoor installations do not require a weather-tight
enclosure.
Physical Dimensions: 10.375" H x 4.75" W x 2" D including harness
Weight: approximately 3 pounds
Operating Temperature: -30˚ to +74˚C
PROGRAMMING FEATURES
10 DAY PLANS — Day Plan 1 is the default day plan that will control time switch operation during the normal week timing
plan. The other day plans will control time switch operation for time periods that require a different timing plan with Day Plan
0 being an empty timing plan used for school holidays and weekends.
16 PROGRAM STEPS — Each day plan (1-9) has 16 program steps. The 16 program steps are used to program ON/OFF
times for relay 1 and/or relay 2.
DEFAULT DAY PLAN — The preset day plan that will operate if no other day plans are entered (unless an annual or exception
plan is programmed).
DEFAULT WEEK PLAN — A set of day plans that operate each week unless overridden by an exception plan. The default week
plan permits the assigning of any day plan to each day of the week. The default week plan (1) operates the AP22 every week
of the year. An annual plan program overrides the default week plan program.
ANNUAL PLAN — The AP22 has 36 different annual plans available. Annual plans use an exception-day concept for
programming special events such as holidays, early release days, etc., throughout the calendar.
PROGRAMMABLE DAYLIGHT SAVING TIME ADJUSTMENT — The AP22 automatically adjusts for daylight saving time changes
according to U.S. law. Re-programmable if law changes.
AUTOMATIC LEAP YEAR COMPENSATION — Perpetual type calendar to adjust for the extra day every 4 years
TRANSFER — Allows program data to be transferred from one AP22 to another.
MANUAL OVERRIDE — Allows one or both relays to be manually activated or deactivated from the keyboard. The manual
override will remain in effect until the next programmed step occurs.
AP22 Programming Manual

PROGRAMMING INTRODUCTION
Programming the ON/OFF functions of the time switch begin with entering a program step time into a day plan(s).
DAY PLAN — A day plan is the programmed ON/OFF steps for a single day. Each day plan has 16 program steps. Day plans
are assigned to a day of the week in the week plan.
WEEK PLAN — This programming format gives flexibility for having a completely different timing plan for any day of the week.
ANNUAL PLAN — This feature uses an exception-day format that allows the operator to assign any day plan to run anytime
throughout the school calendar. There are 36 annual plan program steps available.
CURSOR — The flashing square character indicating the data entry fields of the AP22. The cursor indicates the data at that
position can be entered or changed by using the AP22 keyboard.
ENTER () — This key is used to finalize every data entry procedure. Pressing the ENTER () key will enter the data at that
position into the AP22 and move the cursor to the next program field.

steps from step 00 through step 15. Each step of the day plan is an
event time that can be used to turn relay 1 or relay 2 on or off.
Day plans 2 through 9 are programmed for schedules that
are different from the normal day plan (i.e.: Day Plan 2 could
be programmed as an early release day; Day Plan 3 could be
programmed as a summer school day; etc.)

PROGRAM THE DEFAULT WEEK PLAN
The default week plan is the school schedule the AP22 runs every week.
After programming all the day plans, assign any day plan to any day of the week to accommodate the normal weekly
school schedule.
The default programming for the default week plan is shown above. Day plan 1 is automatically assigned to operate
Monday through Friday. No other programming is necessary if the schedule is the same for Monday through Friday.
However, if a school has an early release day every Thursday, the Day Plan for the early release day can be scheduled
to run every Thursday. The example above shows Day Plan 2 being programmed to run every Thursday. If Day Plan 2 is
programmed as an early release, the AP22 will run this schedule every Thursday.
1. From the MAIN DISPLAY press WEEK PLAN (C) then ENTER ().
2. Press Cto advance to the weekday to be programmed,
then ENTER ().
3. Press 2to program day plan 2 to run every Thursday,
then ENTER ().

PROGRAM ANNUAL PLANS
The AP22 has a total of 36 different annual plans. The annual plan feature uses an exception-day concept for
programming school holidays, spring break, early releases, the start and end of summer vacation and summer
school, etc. The system works by entering the month, day, and year the annual plan will start, and the month, day
and year the annual plan will end. If it is a one day exception, only the start date needs to be entered (for example,
Steps 00, 01, and 03 shown below).

SCREEN 0A — ANNUAL PLAN PROGRAMMING
This screen is used for entering annual plans. These plans select a
date range, then a day plan that will run within the date range. There
are 36 annual plans from plan 0 to plan 35. Select day plan 0 to have
no relays activated.
The time switch will not run properly if annual plans overlap. The time switch runs the day plan of the first valid annual plan it
finds for the day. If there are other annual plans that are in the same range they will not be used.

Exception? 00
SCREEN 01 — MANUAL CONTROL
This screen turns a relay on or off manually. The relay will stay
in the programmed state until a different calendar event is
processed.
SCREEN 03 — SET TIME
This screen allows the hour and minute to be set. By pressing
ENTER (*), the seconds field is set to 0.
SCREEN 04 — DAY OF WEEK
In all versions of AP22 4.04 or earlier, this screen allows the
day-of-week to be set. In CP22 versions, the time switch correctly
enters the day-of-week based on the date entered (see Screen OD
on page 25).
SCREEN 07 — DAYLIGHT SAVING TIME SETUP
This screen allows daylight saving time to run in the time switch.
Enter the month and the weekend the time switch should enter or
exit DST. The AP22 will default to these current U.S. standards:
S(Spring), M = 03 (March), SUN = 2(second Sunday)
F(Spring), M = 11 (November), SUN = 1(first Sunday)
To disable DST enter the Spring month as 0.
