Hi No Ladders,
I see that the electronic switch timer/controller on the Thermo top is now model 1533 which can only be set to run for an hour max and then has to be reset.
How does yours work? Will an ordinary on/off switch work or do you keep having to reset the controller during the day. I believe that the initial fire up occurs when pin 1 is given a 12v current supply, but someone said that he thought that the controller then kept a lesser voltage to that pin 1 of 7v.
Thanks
