Check Your House Temp By Phone
Phone-Stat is a temperature sensing instrument that connects directly to your telephone. You set it at a temperature which you want to maintain while you're gone. Then, you simply call home whenever you want to check the temperature.
If the temperature is staying safely above the level you set, your phone will give a normal ringing signal. However, if the temperature drops below the setting, you'll get a busysignal when you call home. That's your warning to call a neighbor or service man and have your system checked.
Since nobody answers your phone, your checking calls are "toll-free". Call as often as you like from any distance ù at no cost to you.
The Phone-Stat operates on any single party line. It plugs in to a telephone jack, or it can be connected with a screwdriver. It uses no power and requires no maintenance, and it doesn't interfere with normal telephone service.
Phone-Stat is sealed in a dust-tight box. It can be set from 30 to 110? F. Sells for $89.95.
