To use the remote control to delay the driving of the fan

Summer will come soon. The temperature is becoming higher and higher. Fans and air conditioner are necessary. My friend  wanted to buy a remote controller to control switch delay. She would like it to control the fan in bedroom to turn off automatically after her daughter slept. It is very energy-saving and money-saving. So I found the following remote control kit, Model 0020258(S1DA-AC220+C-2)

The major characteristic of this model is switch delay. It has a timer in the receiver. So we can adjust delay time from 0 second to 99 hours according to their requirement.
 The wiring is also very easy.

From the wiring picture, wires from the fan should be connected the B&C terminal of the receiver respectively. First of all, Press buttons of “+” and “—” on the timer and adjust delay time. If customer wants to fan be off after 2 hours, he will set “H 0 2”, it means the delay time is 2 hours. Then we press button 1, the fan begins to work. After delayed time, the fan will turn off by itself .If we press button 2, the fan is turned off immediately. There is no need to wait for delay time.  

One remote controller control some shutters in the house simultaneously

Recently, my friend moved into his new house, a very spacious house. He intended to buy remote controllers to control his reversible motors shutters. He wants one transmitter to control 4 shutters in each room. The Model 0020337(S1FM-DC12&CV-2) is favorable for him. This set of controller can make the motor rotate in forward and reversal direction.
This is the transmitter and receiver. From the transmitter, we can see two buttons on it.
Button ▲ on transmitter & receiver is for forward direction. Button ▼ on transmitter & receiver is for reversal direction.

My friend wants to control like this:

Each of the receivers should learn code from the transmitter so that the transmitter can control 4 receivers simultaneously.
Here is the wiring picture.
Each motor of the shutter should be connected to the receiver one by one. Every receiver should be connected to the power supply.

He presses and holds button ▲ on transmitter. With the motors of shutters working continuously in “UP” direction, shutters go up slowly. When he releases the button ▲, the motors stop moving. When we press the hold button ▼, the motor works continuously in “DOWN” direction, shutter go down slowly.
