AHHHH!

I understand now.

The mud is cleared away.

Thank you for taking time to help me out.

God Bless.

These switches are on a PTAC (packaged terminal air conditioner) unit with electric heat coil. In heating mode: Does the switch turn the blower on at 145* then when it drops 40* to 105* shuts it off? The other is the high limit. Turns the blower on to cool the coil down if the operating switch fails...

Thank you for the reply. Another question....the L145-40 is at the top or beginning of the coil and there is another at the bottom or end but it is labelled L160-40F. Is this the high limit switch and the first one is the operating switch? Could you explain to me how these work with the thermostat? ...

Need a little education on a switch. This is not the exact one but very similar. It is installed into a ptac unit with resistance heat. The company wants to sell me a entire coil assembly but the problem is just the switch. So I am looking for just the switch. Heres the link: http://www.hvacpartstor...
