Ritetemp thermostat install.
The old thermostat has
Y- yellow wire
G - green wire
R- red wire
O - orange wire
W2 - white wire
E - brown wire
C - no wire connected

New Ritetemp has:
G - terminal
RC
RH
W
Y
C

Any suggestions how to wire the new one? Thanks! Zeke39

The old thermostat looks like it is for a heat pump with 2 stage heat.

The new on is not for a heat pump and does not have 2 stage heat capability or a reversing valve connection.

In short the new thermostat you have will not work.

Thanks hvac1000,

The new thermostat was here when I moved in and now I know why it wasn't installed! Time to go shopping. Any suggestions on a decent thermostat?
