"Dad, why is the garage door open?"
My 20yo daughter and her boyfriend had stopped by to finish the last bit of sanding the brand new sheetrock in my brand new 4-car garage and the wife's garage door was wide open in -20 F weather, and had been open for at least 7 hours. She knows to watch the door go down, but built-up ice apparently reversed the door milliseconds after she turned her eyes away.
The consequences:
The $300 dehumidifier reservoir froze solid and broke.
The $80 programmable thermostat is totally blank and nonresponsive. Past experience with it taught me that it turns the furnace off below 30 F anyway, so at least I wasn't heating all of Alaska for at least 6.9 of those 7 hours the door was open. A new $30 brainless Tstat got the 75K Modine back on and the building 70 degrees warmer in only two hours.
I was planning to prime/texture/paint the drywall this weekend, but the previously-mentioned brand-new sheetrock has 16' of brand-new cracks, so I get to fix those today so I can keep on schedule.
Nothing was stolen!
So: What can I do to prevent this from happening again?
A low-temp phone alarm needs a phone line, and the new ethernet/phone/satellite/alarm conduit is full of hard water for the next 7 months.
Door switches and flashing strobes?
Iphone alerts triggered by temp and door switches?
Irregular beatings?
Do the Chamberlain openers have a wifi status bit?
Go back to manual operation for the duration of winter?
How have you guys dealt with this problem?
