One other trick, the temperature on most digital thermostats can be ‘adjusted’ about 3 degrees up or down.

However, tenants complain that they want temperature to be 70 deg and AC can't do it.

Other advantages are that they are quieter, less dust, occupy less space, if one breaks down it doesn’t affect the entire house and every room can be at its own temperature.

Ultraloq U-Bolt Pro: This lock is weather-proof and can withstand temperatures from -4 to 140 degrees Fahrenheit.

They cut my flat PVC roof in two areas and caulked their patchwork instead of welding it.

I tested it and the water pressure and is pretty good and there is nothing wrong with the temperature control.

The thermostat shows the temperature at only one location.

However, there is a theoretical limit based on the thermodynamic cycle  as to how much they can heat a house when the outside temperature drops.

As we scale up the number of properties we are managing, we have been looking for a good all in one system to keep a better eye on things like: leaks, break ins, power outages, temperature, surveillance and keyless entry.

Programmable thermostats are indeed legal as long as you have them set to the minimum required temperature.
