Hello all,
In thinking about how to use cold well water, a
radiator and a fan to air condition or at least
partially dehumidify a small building I realised that
the DC pump I am using in the well would need to be
turned off and on from the building about a hundred
feet away, not a great distance but something else to
buy nonetheless and wire is not cheap these days
anyway. I thought perhaps a remote controlled switch
would be perfect. If I can turn on my television with
a remote surely I could turn on a pump from only a
hundred feet away? This would be handy.
Then I thought about the whole issue of remote
switching and wondered if there was a manufacturer of
such thing ? I have done no research on this at all
but thought it might be something someone here could
answer in a blink. I am hoping it doesnt need to be a
computer controlled wifi sort of thing rigged to a
cell phone so I can call ahead to start the system or
indeed have it thermostatically controlled...
Thanks anyway for so far.
Michael Lough

Maybe something like"
Craftsman Plug In Light Control for Garage Door Opener
Sears item# 00953786000
You might need to add some sort of relay to power the pump...
Maybe even the whole garage door opener system, just wire your pump up to
where the drive motor is...

There are all kinds of remote controlled switches but
why would you need it? Low voltage wiring isn't very
expensive (100 feet of 2 conductor 22ga can be had for
around $20) and isn't hard to find. It doesn't take
much to activate a relay.
That said, a quick websearch on 12V DC remote controlled
switches got me the following...
Logisys RM01 12V 6A Relay with 2 Keychain Remote Controls RM01 $15.00

Logisys RM02 12V 15A Relay with 2 keychain Remote Controls RM02 $17.00

They claim a range of 40-80 feet but I think you could
manage more with better antennas and direct line of sight.

Couldn't you put the switch on this end of the wire going to the well?
That's how my well works. The pressure switch is in the garage and only the
power line runs out to the pump.
But I think you might be underestimating how much power the well pump needs
to run. I'm not sure you will be saving any power using it to cool your
building.

I think this needs AC POWER?
THANKS ANYWAY!!

The wire runs directly from a 12 volt battery to the pump at around 85
feet down from grade into the water. (I will eventually have it
running from a charge controller /solar panel ) The wire that runs
from the battery to the pump is 12 guage The pump needs 8 amps on
surge (I think). I take the comment about having the switch at "this"
end on the wire but 12 guage two conductor wire would be around 180.00
here with TAX in. Enough to make me think. The Logisys 12v 15Amp
relay seems like a contender but I wonder if we cant find a longer
range bit of gear?

I am running the well pump (Nemo solar 12volt pump) off an 85 amp
Concorde deep cycle battery and it will filla 5 gal bucket pail in 4
minutes this water at around 9 degrees centigrade above freezing year
round could run to an insulated tank which then could be circulated
through a car radiator inside the building with a small 12 volt garden
pond pump (still looking) This would have a small fan also solar
powered in the small building forcing air through the rad the
condensate would drain to a discharge hole in the floor. It might be a
good idea to make the insulated tank the switch for the well pump some
how so that when the temp of the water which is being circulated
through the tank goes up it turns on the well pump (and causes to
tank to overflow outside the building ) until the water returns to 9
degrees when a thermostat switch could turn the well pump back off.
