To use this you will need:
screwdriver, wire clippers & strippers
a 12 VDC powers source (to power the unit)
a relay where 12VDC controls 120 VAC (might be $10)
wires to connect the relay to the controller
an extension cord cut in half to go on either end of the second relay
(supplying power for the heater to the relay and to supply controlled power to the heater)
any old heater could be used as the controlled heater, even one that is stuck on
cheap yep, but a bit of work there too....LOL....
