Good features, but missing one important option: you can't adjust heating cycles. It's just on-off, on-off and the display temperature never changes. That's good for keeping temps even, but not efficient. Also, the space for connecting the wires is really tight.
Had this installed. Had to call a pro because the correct colors for the wires were not used by previous installer. Love the fact I am able to control thermostat from a distance since it is stalled in a vacation home. Would recommend it without hesitation. would give 5 stars other wise
