WattStopper Digital Time Switch


The TS-400 Series WattStopper InteliSwitch is a digital time switch that automatically turns the load off after a preset amount of time. The load can be turned off anytime during the timer's countdown by pushing the on/off button. Designed specifically for building automation systems, BAS, these time switches have four user-adjustable features: Time-Out Delay - The timer can be adjusted to hold the load on for five minutes to 12 hours. This is adjusted by setting the on-off button located on the left side of the unit. Time Scrolling - In situations where the load needs to be held on for a different amount of time than the preset time out period, time scrolling allows the user to manually and temporarily override the time out period. Flash Option - If this option is on, the load will flash once, one minute before the time-out period expires. Set this option with the on-off switch. Beeper Option - If this option is on, the timer will beep every five seconds during the last minute of the time-out period. Set this option with the on-off button.
