I am trying to replace a manual with programmable thermostat that is missing emergency heat (E) terminal. There are bits and pieces of information I have gathered but am still not clear.
Can I leave off (E)?
Manual thermostat (th3210d1004) terminals:
E|AUX|Y|G|O|L|R|B|C where L,B are not used
Programmable thermostat (TX1500E) terminals:
The plan is to wire: R->RH,RC
All the other letters are matched. Is that correct?
