Trane Programmable Thermostat

We had a new Trane heating system installed in March and pout with a Trane programmable thermostat 800. The touchpad does not work on it, is it my fault and I'll e have to call the service or is there something I can do to fix it myself. I can not do anything with the touchpad, I tried to take the batteries, but it will not "reset" Thank you

Have you tried replacing the batteries? If this does not invoke the program installer and have them replace the stat.
