    A friend of mine wants WiFi thermostats installed, so he picked out Honeywell TH9320WF5003. I'm connecting these to heat pumps with electric heat strips. I noticed on wiring it has a "L" terminal, sends output when set to emergency heat. Where is it sending it too? I ASSume there might be an indicator light on this stat.

    Historically “L” is a signal coming from the equipment to show a fault or fault light at the thermostat.

    Don’t know anything about using l to send a signal in emergency heat mode. Maybe could use it to lock out heat pump?

    Looks to me like a homeowner style manual Honeywell has the trade line and the HO line. Much better warranty on the trade line.

    The one he wanted was from HOME CePot, he asked how much I could get them for. He gave me the part #, when I called JS they said it was "Retail version" like you stated too. Just wanted to make sure he's his money's worth out of these stats.

    And they jerk you off on warranty in years 3 thru 5

    Can’t go by the install date, actually need to find the invoice from when you bought the thermostat from the wholesaler and they go off that.

    So I didn't bother with the "L" terminal, their existing stat didn't have it hooked up. So now they say the auxiliary heat is cycling on when they rather use just the heatpump. This wonderful stat doesn't have a aux heat lockout and there is no setting for the deadband. I called HW to verify, they said to install a outdoor stat to lock out the aux heat. Any recommendations on simple outdoor stats?

    That's what I was thinking, wasn't sure if they made something else.

    Can't get much simpler then that!

    digital is a little more $ but the control is inside.
