The ICM315 is a reliable, solid state replacement for Ranco E15-type controls. It uses a thermistor-type probe as opposed to the unstable bulb-type sensors used with E15 controls. The ntc-type probe of the ICM315 is less susceptible to breakage. Unlike E15 controls, the ICM315 is not “position sensitive†and therefore not susceptible to “re-initiation phenomenon†which can cause damage due to short cycling. The ICM315 provides a selectable time interval (30, 45 or 90 minutes) between 10-minute defrost cycles. Upon application of power, the timing sequence begins with the run period first, and then the 10-minute defrost period. When the thermistor senses a temperature of 28ºF or lower, the defrost board will be controlled by its internal timer. The relay will be energized every 30, 45, or 90 minutes based upon the pin selected. If during the 10- minute defrost period, the temperature rises to 55ºF or greater, the defrost period will terminate. If this condition does not occur, the defrost period will complete and the entire sequence will repeat. The on-board relay (K1) will be energized only during the 10-minute defrost period.
