Mode of operationThe ICM300 provides a selectable time intervalbetween defrost cycles. It will allow a 10 minutedefrost every 30/60/90 minutes as long as the DFTis closed. A HOLD input allows the timer toaccumulate time while the compressor is running.Additionally, a warm coil causes the DFT to openwhich will prevent time accumulation or end thedefrost period. When the defrost period ends, eitherby opening of the DFT or after the 10 minute defrostperiod has elapsed, the timer is reset.Each ICM300 is shipped with detailed instructions.Consult factory for variations not listed.

DEFROST TIMERS SERIES 315
6333 Daedalus DriveCicero, NY 13069
Low cost, high performance solid statedefrost control replaces E-15 typecontrols, uses nyc-type sensor...The Series 315 is a reliable, solid state replacementfor E15-type controls. It uses a thermistor-typeprobe as opposed to the unstable bulb-type sensorsused with E15-type controls. The ntc-type probeof the ICM315 is less susceptable to breakage.Unlike E15 controls, the ICM315 is not “positionsensitive” and therefore not susceptable to “re-initiation phenomenon” which can cause damagedue to system short-cycling. The ICM315 is easyto mount and features a heavy-duty relay output.
EnvironmentalOperating Temperature• -40°C to + 75°C, -40°F to +167°F
Transient Protection• Meets IEEE 587 Standards for Categories A & B without false
output or degradation.(6Kv 0.5 µs X 100 KHz Ring Wave) (6Kv 1.2 µs X 50 KHz Impulse Wave)
Mode of operationThe ICM315 provides a selectable time interval(30/45/90 min.) between 10 minute defrost cycles.Upon application of power, the timing sequencebegins with the delay period first, and the 10 minutedefrost period second.When the thermistor senses a temperature of 28°For lower, the defrost board will be controlled by it’sinternal timer. The relay will be energized every 30,45, or 90 minutes based upon the post selected. Ifduring the 10 minute defrost period, the temperaturerises to 55°F or greater, the defrost period willterminate. If this condition does not occur, the defrostperiod will complete and the entire sequence willrepeat.The on-board relay (K1) will be energized only duingthe 10 minute defrost period.Each ICM315 is shipped with detailed instructions.Consult factory for variations not listed.

DEFROST TIMERS SERIES 319
6333 Daedalus DriveCicero, NY 13069
Ultra low cost heat pump defrost timer.Direct replacement for Nordyne 624519A...The Series 319 integrates multiple time andtemperature defrost functions onto a low cost,conformally coated, open board package.
• HOLD feature tracks compressor run times• Time and temperature terminate• 10 minute fixed defrost time• Pin-selectable: 30/60/90 minute defrost intervals• On-board test pins reduce test time by 256X• Recycle function melts frost on coils• Stable pin post construction•
R
recognized: E118867
EnvironmentalOperating Temperature• -40°C to + 75°C, -40°F to +167°F
Transient Protection• Meets IEEE 587 Standards for Categories A & B without false
output or degradation.(6Kv 0.5 µs X 100 KHz Ring Wave) (6Kv 1.2 µs X 50 KHz Impulse Wave)
Mode of operationThe ICM319 provides a selectable time intervalbetween defrost cycles. It will allow a 10 minutedefrost every 30/60/90 minutes as long as the DFTis closed on the DFT terminal A warm coil causesthe DFT to open which will prevent time accumulationor end the defrost period. When the defrost periodends, the timer is reset.Each ICM319 is shipped with detailed instructions.Consult factory for variations not listed.

DEFROST TIMERS SERIES 320
6333 Daedalus DriveCicero, NY 13069
Low cost, high performance solid statedefrost control...The ICM320 is a high performance defrost controlwhich serves as a low cost replacement for CarriersHK32FA006. The ICM320 features stable pin postconstruction and conformal coating for greaterreliability in harsh environments. On-board testpins reduce test times by 256 times.
The ICM320 is easy to mount and features heavyduty relay output.
EnvironmentalOperating Temperature• -40°C to + 75°C, -40°F to +167°F
Transient Protection• Meets IEEE 587 Standards for Categories A & B without false
output or degradation.(6Kv 0.5 µs X 100 KHz Ring Wave) (6Kv 1.2 µs X 50 KHz Impulse Wave)
Mode of operationThe ICM320 provides a selectable time interval (30,50, 90 min.) between defrost cycles. Upon applicationof power, the timing sequence begins with the delayperiod first, and then the 10 minute defrost periodsecond.Defrost Terminate Input: When open, will terminatethe defrost period and reset all times.The “Y” terminal will temporarily shut off the defrostcycle to track compressor run times.The on-board test pins reduce test time by 256x.See chart above.
