    You are partially correct.
    The machine not the (wired or wireless) remote or timer controls the reheat cycle.
    When the heated tube is unacceptably below operating temp a thermal switch located on the tube assembly diverts power from the light on the remote and the fluid pump.
    As I recall the lights are just wired in parallel with the pump, so when power again becomes routed to the pump, the light on the remote tells you the machine will run the pump if you close the switch on the remote. Look a the threads and articles covering triggering the fog machine by replacing the remote with a relay for confirmation.
    If you think I'm wrong google: fog machine remote
    In fact here is a good result, deals with making one remote work on a different brand of machines.

    The timer versions work almost the same way, but have a circuit to press the switch for you at what ever interval (and duration) you have set on their dials.
    Reheat frequency and duration are controlled in the machine, by how much heat (wattage) you can supply, and how much fluid is passing through.

    Wireless versions just insert a RF link in place of the wires, so any connection (LOR relays) that work on a wired remote should work on a wireless fog machine too.
    Machines will not respond unless the thermal switch in the machine has reached operating temp and enabled the demand switch (the wireless remote receiver).

    I've said it before, and I will again. If you're in the market for a nice, economical fog machine, I'd recommend the one from Spencers all day, any day.

    http://www.spencersonline.com/produc...-with-timer11/

    It comes with a timer, so you can just turn it on (and the timer) and walk away. It's 700Watt, so not the biggest thing out there, but will put a nice mist in a corner of a yard just fine with some quality juice (NOT the spencers juice!). And, is cheap enough you could get a second to cover another corner if you want for the same price as a bigger fogger.

    2 spencers fog machines, ran through corrugated pipe, froggies swamp juice:



    That said, if you want a BLANKET of fog instead of a mist, you'll need to go bigger.

    Chauvet 1300, fog chiller, Froggies freezing fog.




    Thing is, you want the timer. That's your turn on and walk away ability.

    UNLESS you buy a continuous fog machine...but they are PRICEY!!!

    I figured out why you call yourself that - you spark unorthodox thoughts and ideas in others. - Hallomarine

    The first one I ever bought had the remote, but there was a button/switch on it for basically continuous operation.

    Keep in mind, even continuous operation will stop every so often as the machine cycles and re-heats the heater element.
    One thing you could do is crack open the remote and wire a 120 volt operated relay across the switch contacts. That way, you can have the fog machine fire whenever you turned on power the lights, or whatever you are trying to do. Just a thought...

    LOL at how the answers wander about, but are mostly correct.
    I'm guessing OP didn't have an in depth understanding of fog machines, and just wanted one he could leave switched on so his LOR could apply power on cue and have instant fog.
    However most fog machines don't work that way. He can as suggested replace the switch in the "remote" with a relay, and power the relay with his LOR. But he asked for ones w/o remotes, I assume thinking the remote caused the lag in (or lack of) response.

    If the above is his goal, he needs to understand a few things.
    Sometimes the machine won't respond because it is reheating, and it's not the remotes fault.
    Even while not making fog the machine will eventually cool down to the point where it goes into reheat mode for a minute or so (depending on the machine).
    For more money he can get a machine that will be available for fog almost all the time, but still not when AC power is first applied.
    He could use two cheap ones, perhaps add a circuit that enables only one if both are ready, But it is likely sometimes (but fewer) he will still have no output on cue.

    Like most places, here he will find the better formed and detailed the question, the better are the answers.
