[. . . ] 120-277 V. A. C. Description The Intermatic Electronic 24 Hour Time Switch automatically switches loads according to a preset daily schedule. This time switch is designed to directly switch loads up to 30 amps and to switch resistive or inductive loads up to the time switch rating. For use as a control timer in applications requiring 24 hour load control such as lighting, heating, air conditioning systems, pumps, etcetera. Up to eight set points or events (4 ON/4 OFF) can be preset. [. . . ] simply press in and downward (in the direction of the arrow) on the battery cover which is identified with the word "Battery". It is recommended that the battery be replaced with a "AA" industrial grade alkaline cell at two to three year intervals as part of the normal time switch maintenance observing battery polarity markings when installing. No other maintenance is required. Knockouts FIG. #2 NOTE: For 120 Volt loads only since the timer voltage is 120 VAC a jumper can be added between terminals 2 and 3 to supply load power. CAUTION: Do not use jumper if load(s) are not 120V. Supply separate power of the correct voltage to terminal 3. 8. Place the selector switches in the "MANUAL" and "RUN" positions. Reapply power to the time switch. Install Jumper Only If Timer Input and Load Voltage Are The Same, Otherwise provide a separate source of load power to terminal 3. FIG. Press the reset switch for three to five seconds. Refer to the chart below and enter the scheduled events (set points) required. EVENT On 1 Off 2 On 3 Off 4 On 5 Off 6 On 7 Off 8 TIME NOTE: For 120 Volt loads only since the timer voltage is 120 VAC a jumper can be added between terminals 2, 3 and 5 to supply load power. CAUTION: Do not use jumper if load(s) are not 120V. Supply separate power of the correct voltage to terminal 3 and 5. Neutral 120 VAC Hot Programming Steps Refer to programming instructions on time switch door label and note the following: · The MANUAL/AUTO selector can be used to temporarily override the program. Under normal operation the selector should be in the AUTO mode. The MANUAL mode maintains the program but prevents the loads from automatically switching. · The other selector switch is used to set the time of day (TIME SET), the program information (PROGRAM) or to run the program (RUN). FOR A PROGRAM TO FUNCTION PROPERLY, THE TWO SELECTOR SWITCHES MUST BE IN THE AUTO AND RUN POSITIONS. · The RESET switch is used only prior to initially programming the time switch or to erase all programmed set points. · By holding the hour and/or minute buttons depressed you can achieve a fast roll of the displayed time. This is useful when setting the time of day or setting the programmed set points (events). · Up to 4 ON and 4 OFF set points (8 events) can be programmed. · The load can manually be switched ON or OFF at any time only if the selector switch is in the RUN mode by pressing the ON/OFF button.
