DTMV Universal Replacement Multi-Voltage Defrost Timers
Time initiated, remote temperature, pressure or time terminated universal replacement defrost control.
The DTMV is applicable to air defrost (compressor shutdown) and in electric or hot gas defrost
systems where the defrost is terminated by the timer or when the coil is frost free, as sensed by
a temperature or pressure switch, even though the programmed defrost termination time has
not been reached. The time termination functions as fail-safe and will terminate the defrost
if the temperature or pressure switch fails to do so.
FEATURES:
• Multi-voltage field adjustable for 120 or 240v.
• Real time clock face.
• Red or green LED lights indicate defrost or run cycle.
• Captive trippers can’t be lost. Independently adjustable trippers
allow for full or partial defrost cycles.
• NEMA 3R outdoor enclosure standard.
• Existing board easily retrofits into competitive enclosures.
• 30 amp rated contacts.
