Question: Will it call me when the power goes back on or temp goes back to normal?
Document: A lot better than the freeze alarms you have to call. Just plug it in and it was easy to program. It has a battery backup and it will call you if the power goes out.
I have one in my basement to call me if my sump pump quits, if the temperature goes low (heating quits) or if there is a power failure. Works as advertised, no complaints. Great idea for the price.
Works well. Installed in our second home in New England. Already called us about a power failure this last snow storm. Power came back on shortly after and unit did not need to call again. Saved us a lot of worry.
We put this alarm in our house on Block Island. Installation and setup are simple. So far it called me 3 times for loss of power during storms. I'd like it better if it could call back when the power is restored but I think that's a function for more complicated models.
Bought this product because transformer fuse kept blowing at secondary home. Wouldn't know electricity was out for several days and by then all the food in the refrigerator would be ruined. This happened every six months or so. Now I'll know very quickly when the power goes out and call the electric company so they can replace the fuse. Having it also warn me that the heater has malfunctioned is a bonus.
The THP201 is well made, simple to program, works as stated and priced right. I've tested for both power out and low temp and have confirmed the proper operation.
I own "the house with the web basement". As long as the power is on, the water goes into the French drain and into the sump pump basin. But if the power goes out, as it often does in my area, I have about 15 minutes to get the generator going before the water reaches the basement floor. If we are away from the house, we are in trouble.
If I don't answer, it calls my wife. We could add a third number, but haven't. So far it has saved us twice, saving our oil boiler, washer and dryer, and water heater. Well worth it. The only key requirement some overlook is that you need a telephone land line, vs an internet phone, which is out if the power goes out. If you have anything that needs to be running at all times, you need this device.
It was easy to set up and test, and worked as advertised. I haven't experienced any power failures or low temperature situations to really test it out. I would have preferred to have the temp limit at 55 deg F which would give you more time to react in case of a heat failure, but all the competitors that I checked out had 45 deg F settings. For the price, it's good insurance.
limitations and features should have been available for consideration before opening box I didn't expect the 45 deg.non-adjustable temp. setting
Answer: yes
