There is no reset button on this thermostat. To perform reset operation, press the up and down arrows simultaneously, while moving the system switch from OFF to HEAT.
The only reset I know is what the instructions say to reset back to factory reset position is mentioned in the troubleshooting section of the instructions. By pressing the up and down arrows and move system switch from off to heat at the same time. This resets the factory defaults to configuration menu. If it has power, has been reset and still does not function correctly contact your place of purchase. Make sure all your wires are hooked to the right terminals. I've had mine for 2 years and never had any problems with it.
"Filter" and "Battery" are actually two separate messages. They indicate, respectively, that the filter may need to be replaced (based on the time frame programmed at installation) and that the battery is low. We are not sure about the other code, but perhaps the unit needs a battery replacement. Please refer to the manual linked below for more information. http://s3.pexsupply.com/manuals/1249544587127/White_Rodgers_1F86-344_Instructions.pdf
If you don't have a user manual you should download one from the PexSupply website. I don't know what the code "filter battery" means, but the two AA backup batteries which supply backup power to the thermostat are easy to access. You just pull off the plastic cover with your fingers and the batteries are right there. There are grooves all around the case and entire front pops off. I don't think the thermostat needs any batteries to work properly. I think it is normally powered off the thermostat wires and only uses the batteries to retain memory if the line power fails.

This thermostat, 1F86-344, is the recommended replacement for the obsolete 1F86-444.
This thermostat has a temperature range of 45°-90°F. If you want the room to be warmer than 70°F, you must set it between 71°F and 90°F.
set it at 70
Move the system switch over to COOL and press the down arrow button until you get to your desired temperature.
Batteries are located along the top of the base of the thermostat. See page 2 of the manual ( http://s3.pexsupply.com/manuals/1249544587127/White_Rodgers_1F86-344_Instructions.pdf ) for more information.
The batteries serve as a backup in the event of a blackout or electricity problem.
Your thermostat was accurately calibrated at the factory but you have the option to change the display temperature (+ of - 4 degrees) to match your previous thermostat. You need to perform configuration step 6 described on pages 4 and 5 of the manual ( http://s3.pexsupply.com/manuals/1249544587127/White_Rodgers_1F86-344_Instructions.pdf ).
