    Hi Guys, can anyone tell me how to connect this timer switch to my geyser.

    I have attached the photo of this timer switch. I know that from the geyser circuit breaker I must connect the live to L on the timer switch and then the neutral from the geyser circuit breaker to the N on the timer switch. I need to know what I need to connect to positions 1, 2 and 3?


    Any help will be appreciated.

    If only I knew what a "geyser" was? are we at Yellowstone?
    Context is everything.

    Hello,

    I think you are talking about a boiler (a heated water resevoir).
    When the isolation is good enough you can use the timed powersupply.

    Terminals 1,2,3 are a set of voltage free contacts so.
    Looks like terminals 1 &2, in series with the live of your geyser.check with a multimeter that terms 1&2 make contact when timer is active.

    I'd think geyser is a waterfall or fountain pump???

    Do you not have the manual for the timer? Got a manufacturer/model number?
    Looks like those terminals are maybe for switches/contact closures to trigger the timer or override it or something..

    I'm hoping that he is talking about a geothermal phenominon - that would be cool...

    I command nature's geothermal forces, with this unassuming relay. If only I were Chuck Norris, I could ditch the relay.

    Actually a Geyser is a water boiler, used to heat water for domestic use, bathing, showering etc...It probably is a word from the Dutch as I am in South Africa.

    Terminals 1, 2 and 3 should go back to the geyser, which will allow the timer to control the current, allowing the geyser to switch on and off via the setting on the timer. I just dont know what I should connect to 1, 2 and 3.

    L & N need constant power. this is what keeps the timer powered and timing.

    #2 is the common terminal, #1 is normally open and #3 is normally closed.

    You would probably want to do the following:
    wire your hot wire to L and terminal 2.
    Wire your neutral wire to N and to the geyser.
    Wire terminal 1 to geyser (it will replace the currently installed hot wire)

    Double check that the relay contacts can handle the current draw of the geyser.
