Defrost timer (with fan delay):

• Installing the Electro 11 pin plug-in series of control and timing devices is simple and straightforward since they are designed to fit into a conventional 11 pin base.
• Programmable for either 4 or 8 hours, with a 4 hour defrost cycle every 4 hours.
• When the supply is turned on, the pre-selected 1–60 minute defrost cycle begins.
• Then, the relay flips to the cooling cycle, triggering the pre-programmed 1–60 second fan delay time (which stops warm air from flowing into the room and splashing water), and turning on the fan.
