The ASC-500 Series Delay-On-Break Timer from the ATC Diversified Electronics division of Marsh Bellofram Corporation provides short cycle protection by locking out the compressor for a period of time after a voltage or thermostat interruption. Subsequent interruptions will not increase the delay period. Since the delay begins when the interruption occurs, the temperature control is not affected. Under normal operating conditions, the compressor off time is longer than five (5) minutes. In this case, the use of these timers will not lengthen this off cycle.
These are easy to install two (2) terminal Short Cycle Timers that connect in series with the control voltage and control relay. The 24 VAC model of the ASC-500 Series Delay-On-Break Timer employs a built-in bypass circuit for allowing continuous flow through the thermostat’s cooling anticipator while the timer output is off.
