Hot Water Circulator Remote Controlling

A man wants to use one device to turn on a hot-water circulator in his home for 15 minutes&then has it automatically turn off. He lives in a 2 story wood home&the hot-water circulator is in the basement-maybe a distance of about 30 ft away through drywall&wood flooring.

Wiring program is as follow:

He can  connect delayed remote unit to circulator pump. The receiver is relay output (normally open and normally closed). Power supply for the receiver and the water pump are different. That means it will not cause electromagnetic interference during water pump operation.

Operation:

Press big button: Turn on relay (connect B and C, disconnect A and B). After delay time: Turn off relay by itself (disconnect B and C, connect A and B). Press small button: Turn off relay immediately, no need to wait for delay time.

Press buttons of “＋” and “－” on the timer, adjust delay time from 0 second to 99 hours. “H” is Hour, “M” is Minute, and “S” is Second. As his requirement, he can set “M 1 5”, it means the delay time is 15 minutes. After working for 15 minutes, it will be off automatically. Then the circulator pump stops pumping.

Bow and Stern Thruster of Vessel Remote Controlling

Bow thruster or stern thruster are used in small boats or large vessels, which are driven by electric motors. Both bow or stern thruster can create thrust in either direction which makes the ship or boat turn, also makes them more manoeuvrable as well as allowing them to dock without the  tug’s assistance. But have you ever thought of remote controlling the bow and stern thruster?

Someone wants to remote control his bow and stern thruster with 24V radio system. When pressing the keys on the transmitter, the motors must be supplied with continuous power; and after releasing the keys , the power must be immediately interrupted.

He can connect one key to two wires of CB-2N (triggered by connection of two extended wires), and connect DC 24V power and motor to the receivers S1PU-DC24(high power kit with 24V actuated). When he presses and hold the key, the motors will be supplied with continuous power, and after releasing the key, the power will be immediately interrupted.

Wire motor to the normally open terminal A&B. Wire “A” terminal to negative pole of receiver output contact. Wire “B” terminal to positive pole of receiver output contact. And supply 24V power.
