1) The 8035C can run on batteries only.   (2AA Alkaline)    
The batteries will last well over 1 year.  If the batteries are not replaced the 
thermostat will stop working.           
2) The 8035C can run on the C wire if available.                  24VAC ONLY
As shown in the wiring diagrams, The C wire is the other side of the 24VAC 
heating transformer. If the C wire is used, the batteries are then for AC power 
loss only and will last much longer. The thermostat will continue working if the 
batteries die.              

The 8035C requires batteries to operate 
your furnace and retain its programming in memory. 
Switch MODE switch to OFF and the FAN switch to 
AUTO.
