Alternative for CS3-1B with

Hi,

I have a fan in my bathroom that turns on when the light comes on. Wanting to delay its start I purchased a CS3-1B circuit.
I connected everything up dry and then it came out that I had not paid attention to the minimum load that must be met.

In the specifications for this cube, the load is from 20W-350W
My fan has 7.5W

When I plug it in and wait an interval it does not switch on. When I "add" an 18W bulb to it to add load to the circuit everything works as expected.
I saw another post about adding a resistor to the circuit, but it doesn't make sense that instead of 7.5W the current consumption is 20W. (That's not why you buy LEDs and other energy saving devices).

Have you come across a circuit other than the CS3-1B that has a lower load limit of this 7W?
I ONLY care about delaying the START of the fan. The shutdown after a set interval is built into the fan.

Thanks in advance for the hints.

And try to outsmart it in a different way. Connect a 1 uF/400 V capacitor.
For 50 Hz Xc = 3.2 kΩ, ic = 72 mA. So Qc = 16 VAr.
This is what the meter does not count. And the cos φ of the cottage will improve.


I don't think the retarder hits. Why should it?

I don't understand?
I think the author was asking for advice or a finished circuit. To build a circuit like the one in this link is kindergarten.
