This thermostat requires 2 "AAA" alkaline batteries to operate. If is displayed, the batteries are low and should be replaced. For best results, replace batteries once a year with new premium brand alkaline batteries such as Duracell® or Energizer®. To replace the batteries, install the batteries along the top of the base (see fig. 1). The batteries must be installed with the positive (+) ends to the right. https://www.screencast.com/t/bS0cOO5hX

You can restart it yourself. You can reset the thermostat by pressing the up and down buttons at the same time while moving the SYSTEM switch from OFF to HEAT. This also resets the factory defaults.

I replaced an old mercury tstat with White Rodgers 1F80-0261. It has programability of 5+1+1 whereas the 1F78-151 is 5+2. The F80 is about $20 more than the F78. My biggest reason wasn't the programability but that I could power the F80 off the 24v transformer that powers my furnace gas valve. I had to draw a simple wiiring diagram to see how the existing tstat was wired and figure out what was needed for the F80. All digital tstats need power and the F78 is battery only. If my power goes out the F80 has batteries to remember the program but I use it on in manual so that doesn't matter to me. I wanted a newer digital tstat and I wanted one that could be powered off the system 24v. I am happy with how the F80 works and I like White Rodgers
According to the Installation Instructions, many furnaces have safety devices that shut down when a lock-out condition occurs. If the heat works intermittently contact the furnace manufacturer or local service person for assistance. You may need to clean your filter, clean your coil, or if you are cooling, you may be low on freon.
You need to use the down arrow (located toward the upper-right of the thermostat) in order to decrease the setpoint temperature.
Just push the button down. The first time it will not move just keep pushing it down till you get to the temp you want. Make sure you are heat.
