Install Nest thermostst

[LMi]

Have older heating system. Only have R and W wires at thermostat and only the two terminal options at the furnace. 

May I install a Nest thernstst with only the two terminals at the furnace ?

The best thing to do is use the online compatibility checker:
Thermostat Compatibility - Google Store
