Installing 5-2 progrmmable Honeywell thermostat

My HVAC system has a C wire and so does my old Honeywell non programmable digitial thermostat. In order to save some money I bought a Programmable 5-2 day programmable thermostat (Honeywell). This thermostat does not have a position for the C wire (The other positions are Rh, Rc(connected by jumper to Rh), W, Y, G and it matches with the new one)



The question is - can I leave the C wire unconnected?



If yes, what are the pitfalls of doing so



Thanks

The thermostat doesn't use a common. No pitfalls

I learned that if you don't connect the C wire, it will detonate, usually in 10 hours.

I learned this watching "24".
