Comments about Robertshaw 9920i Programmable Heat Pump Thermostat, with Fresh Air Control:

The residual fan control is really nice if you have units that do not internally control them. They're adjustable 30,60,90,120 so you can return some of the humidity to the home if you live somewhere dry like myself. Programming this unit is as good as it gets, this company was Maple Chase before I believe which had some of the most adjustable thermostats way back when. I'm very satisfied with this unit. I have 2 separate units on the house and adjust them for the seasons, I actually had 2 Honeywell units I bought to replace the Maple Chase units and they didn't have the residual fan control which was really annoying...

Comments about Robertshaw 9920i Programmable Heat Pump Thermostat, with Fresh Air Control:

My house had a more expensive, industrial RobertHunter thermostat, but it didn't have the control I was looking for. I bought this thermostat because it allowed for configuration of a few key items. The difference between the current temperature and commanded temperature before the 2nd stage heat could come on. It also allowed for a configurable delay before the 2nd stage heat could come on. This allowed a bit more control over the 1st and 2nd stage heating. I also got the two remote sensors one for outdoor and one for indoor. (9025i and 9020i). I like that the heating control can be based on either the thermostat or the remote sensor or an average of the two. The outdoor sensor can control whether the 2nd stage heat is allowed to come on in addition to preventing 1st stage heat from activating if it is too cold out. Great easy to read backlit display. It would be nice if it could be activated to read without entering a menu. I was a bit disapointed in the wiring labels between the two RobertHunters. There was a slight difference in the designation of the second stage heating wire. The old one called in E/W1 where the new 9020i called the the second stage W2 but it also had an E terminal. I mixed it up at first but later sorted it all out. Also the time is not battery backed so every time I disconnected the power I had to reset the time and date. It supposedly has an ability to save it for a few hours in the event of a power outage. All-in-all a great thermostat.
