Is it acceptable to use a rate-of-rise heat sensor in a garage? Its in AZ so I have sensors rated for 194 degrees for attic and possibly garage, but I was thinking when you brought a hot car into the garage, that might rise the temp pretty fast, triggering the sensor. Is this a concern? The instructions don't say anything about this case. I have a gas water heater out there, so that is the reason for the sensor.
