This warranty is made by: Intermatic Incorporated, /After Sales Service/ 7777 Winn Rd. , Spring Grove, IL 60081-9698/815-675-7000 http://www. intermatic. com Description The Intermatic Electronic 7-Day Time Switch automatically switches loads according to a preset weekly schedule with to-theminute accuracy. This time switch is designed to directly switch inductive or resistive loads up to 30 amps at 24, 120 or 240 volts and to switch tungsten or ballast loads up to the time switch rating. For use as a control timer in applications requiring 7-day load control such as lighting, heating, air conditioning systems, pumps, etcetera. Up to 20 (10 ON/10 OFF or any combination) set points (EVENTS) can be preset. These set points can be programmed for any or all 7 days to provide for up to 140 set points each week. Independent 7 day programming provides complete flexibility for applications where load switching differs each day of the week. The program can be overridden by selecting the MANUAL position. SET POINTS (EVENTS): 20 total (10 ON/10 OFF or any combination) daily. BATTERY POWERED CLOCK OPERATION: 3 Years minimum (AA industrial grade alkaline supplied with time switch) MIN.

General Safety Information WARNING: Disconnect all power before installing or servicing this time switch or its connected loads. Follow all local electrical and safety codes, National Electric Code (NEC), as well as Occupational Safety and Health Act (OSHA). If the power disconnect point is out of sight, lock it in the "OFF" position and tag it to prevent unexpected application of power. Do not exceed the maximum current carrying capacity of this time switch. Always replace the plastic insulator covering the terminal before turning power "ON". INTERMATIC INCORPORATED SPRING GROVE, ILLINOIS 60081-9698 158ET10371 Installation WARNING: DISCONNECT THE POWER TO THE TIME SWITCH AND THE LOADS BEFORE INSTALLING THIS TIME SWITCH. Mount the time switch in the desired location using the three mounting holes which are provided. Mount the time switch at eye level, if possible, providing sufficient room to the left of the enclosure for the cover to swing open fully. The time switch mechanism does not need to be removed from the enclosure to mount the time switch since the top mounting hole is a slotted type mounting hole. The head of the screw or fastener should be slightly larger than the narrow portion of the slotted hole to ensure that the time switch is securely held in place.
