just to be clear. This is designed to keep something at a certain temp? So the hot end i see heats up between the specific temps listed?

The silver probe tip is the temperature sensor itself. That's what detects the temperature of what ever you are monitoring. When it's above the High temp setting (red) the relay contacts K1 and K0 close so that would activate a fan or what ever you want to monitor. Depending on how you have it setup, if the temp gets below the Low (green) temp, then the relay contacts (K0/K1) open to shut off any cooling you might have running.

Can the relay be driven by 5V DC?

As the description says, the board itself is driven by 5v which powers the relay. The ratings it lists is what the relay contact load can carry.

If the board loses power for an extended time, do the settings reset?

The settings will be saved when the power off.

Upon power up, is P0 set to cooling or heating?

First powered on, the device is cooling mode(can be changed).

It is what is described

Pretty cool little thermostat, works great upon installation, and is what it says it is....Simple no frills just a working useable thermostat. I put it in the inverter compartment on my motor coach to control a fan so as to not overheat my inverter while traveling in the 110-120 degree desert Southwest which has happened. There are a number of settings you can control. This opens and closes the negative circuit as described in the pictures section of its product pageThe thermostat arrived on time and in a well packaged parcel in excellent condition.I can't speak to its longevity, or durability as it is recently been put in service. If that becomes an issue I'll update this review accordingly.

It works but a little confused

Though the unit works, I’m a little confused. It says the unit works on 5vdc. After hooking it up using a 12volt battery and on a solar charger, when the battery voltage drops below 12volts the unit shuts off. If it operates at 5volts, it should still display the temp readings on the display. I’ve tested several times and sure enough, when battery drops below 12volts the unit shuts off. Hopefully someone can explain this.

Item works great

Using it for a Christmas Light display controller box just to ensure the controller board doesn't over heat inside of the enclosure. Worked great.
