I thought it would be an idea to switch on the fan heater so the boat can warm up while I have my dinner. Being lazy, a remote seemed to be an idea. It has just arrived from Hong Kong 13 days after ordering as promised.

It comprises a fob and a circuit board described as a "transmitter".

The instructions are gibberish (as usual) but it seems to control two functions via two buttons on the remote. There is an implication that the frequency can be tuned (but how is a mystery). The switching capacity is 7A at 240VAC.

If it works (and these things normally do) I will in future use it for an alarm reset.

£5.49 postage free!!!!!!!!!!!!!!!!!!
 
Sounds like a useful toy/gadget, but very restricted for a fan heater (less than 2 kW capability). Any link to where you found it?

Rob.

P.S. You'll have to be standing next to the boat for it to work, so again limited usefulness for a heater. I was initially thinking of the remote for an Eber which can be switched by mobile phone...

It would be straightforward to buffer the output but my main interest is for secondary reasons. How secure is it? Is the transmission coded or a simple burst at one frequency?

If my curiosity is satisfied for a fiver, it will be worth it!

Performance review;-

I lost the instructions which identified the correct polarity of power feed but eventually worked it out. Lo and behold! It worked.

I then accidentally dropped a big blob of solder on the receiver which destroyed it.

I ordered another and have the results;-

Maximum range tested around 50 yards through a steel garage door and round a corner. (could be further but that lost my line-of-sight to the light being switched).
The two relays are latching; i.e. one remote push - on, next push - off.
The original key fob (partner to the receiver I destroyed) did not operate the replacement receiver (i.e. the signal is probably coded).

This performance for £5.49 is incredible value.

I bought one of these last year with no particular purpose in mind, but like you was impressed with the capability for the price. Mine has the buttons labelled "A" and "B", but I've also seen them exactly the same with up and down arrows instead. I plan to buy one of those and use it as an anchor remote.

Be careful, they don't look like they are coded, and could activate with a stray signal.

Graham says that his replacement is not activated by the old remote, so there's at least some discrimination going on. I'll have a master switch in the cockpit anyway (operating a contactor on the main windlass supply) so the system will only be on when I'm working ground tackle, and when it's on I don't plan to put any body parts anywhere near it :).

We use a number of remote controls at home and on the boat.

At home we have various outside lights, bore hole pump, drive way gates and garage doors.

On the boat windlass, bow thruster, auto pilot to control rudder as wall as a jabsco type spot light.

Remotes are very common here but do check the range and that the coding can be changed and the number of coding changes.

Mine are all locally made so posting a link would not help you.

My TV remote extender has the same coding as my the people next door and but the coding cannot be changed so some nights we change channels on each others TV. Can be frustrating
