Hi,

I'm doing maintenance to a 400000BTU chiller, but I'm having troubles with the heating section, because it's works with GLP and burners. When I run the system everything Ok, but, don't know how many time after, the burners go off . The problem? Two switches that open the circuit and close de gas valves of the burners. The sensors are S47 and S65. It's easy to reset pushing the boton of each one (Like a presswitch), but I have to do this every day!

The question is, What is the function of this sensor? Can I bypass this sensor?

Thanks for your answers!

We can't really help without some more info like schematic or even where these switches are located. A pic MIGHT help. You can post directly using "Go advanced/manage attachments"
