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

Maple Chase thermostat [ 6 Answers ]
