Timing Mode
Anti-Short Cycle or Lockout

Application of input voltage (thermostat closes) to the timer energizes the load, the S1 option provides a 1 second delay before the load is energized. Removal of power begins the "lockout" and the time delay locks out the compressor. The load is energized after the time delay expires.

FEATURES
  • Can replace all solid-state timers
  • Relay rating of 10 amps
  • No voltage drop when turned on
  • No leakage current in N.O. position
  • No minimum load
  • Optional "delay on make"
  • Transient protected
  • 100% Load isolation
  • Totally encapsulated for protection from harsh environments
