I do not have a heat pump & am trying to inst. A m/c 09620 tstat. I currently have W Y G Rh Rc (Rh Rc jumper) the new tstat has C L R Y2 Y1 E G W2 O B Im unsure where the W wire goes. I have electric heat strips. I understand I must add a comon wire from the trans. To C for this tstat. One diag. shows W going to W2 (w2 E jumper) is this correct?

The maple chase is made for a heat pump,but it should work. Did and instructions come with the maple chase?, you would be much better off trading it for a good honeywell or white rogers,, heat and cool tstat
