DTAV40 Series
Auto-Voltage Defrost Timer
The Grässlin DTAV40 Series Auto Voltage Defrost Timer is applicable
to air defrost (compressor shutdown) and electric or hot gas defrost
systems where the defrost is terminated by the timer. If the coil is frost
free, the timers can also be terminated by temperature or pressure
switches before the programmed defrost termination time has been
reached. The time termination functions as a fail-safe and terminates
the defrost cycle if the temperature or pressure switch fails to do so.
