Roof exhaust fan with too much exhaust
My roof exhaust is too powerful. When the electrician set it up he asked whether
I want it to full power or half. It was set to full power. The exhaust fan takes two 230V lines. What if one 230V line is disconnected will it be half power or will I damage to fan? I am sure to get a fully qualified answer one would have to inspect the connections and such but generally speaking would disconnection the other 230V line be the usual solution? I am thinking of just shutting the breakers to the other line. |

It doesn't work that way. It is probably a 230 volt motor and has two
speeds, which are internally changed. Have him or an electrician come and reconnect it for the lower speed "John" wrote in message ... My roof exhaust is too powerful.

So on really hot days you can turn it up to full speed and other days you can have it on low speed. |

If there's no thermostat, get one installed. -- The e-mail address in our reply-to line is reversed in an attempt to minimize spam. Our true address is of the form . |

Roof exhaust fan with too much exhaust
the notation means that it probaly came from germany and has poles
inside that can be rewired for a different voltage. this has already been done as we don't use 380 in america.
