If you set it out before use, does it come to ambient temp pretty well most nights, within a reasonable time, assuming temps not dropping?

In my experience, the ETX90 takes about 15 minutes up till half an hour to reach equilibrium. One of the great benifits of a small scope!

sure. mine takes about 15 minutes to acclimate. come to think of it, mine has never had an issue with sweating, or fogging up.

I leave mine on all the time, unless I'm leaving the house for more than a few hours (just a safety thing with me). It doesn't get that hot, however

It is based on the outside air temperature, so will vary, but nothing you can set. The instructions mention that.

I would give it an hour to reach temps that warm. There is a timer on it and you can set it ahead of time. I really like this little heater.

I often leave mine on continuously overnight and for several days. Just ensure your heat setting is not too high.

We've been running it since we got it. At first, we had it on medium, to clear the air. After that, which took no more than overnight, we set it to low and pretty much left it there. This has been about 3 weeks.

Yes the outside temp, then inside...the rest have to chage manually until update from Colorado..( But DST and 12/24 are manual inputs)

I'm not sure if I understand the question. Do you mean how long does it take to get up to temp once you set it? Or do you mean how far off from the temp. you set is the machine's thermostat? I find the machine maybe a few degrees offset from what external sources may read. By a degree or two. How long it takes to get up to temp depends on the room space and other factors like air leaks and such. It can raise the temp about 5 degrees in an hour in my set up. Does that answer your question?

I keep the temp. in the house at 58* during winter nights.. [We all have down blankets on our beds.] It has to get really cold for the central heat to turn on. I ONLY turn it on when I go to bed and usually the second time I wake up [during the night] I turn it off. My heating bill is much less that my A/C bill in the summers!

No it doesn't, at least the model that was on sale a while back (and I don't think it's changed). It takes a long, long time to reach the required temperature and then gradually climbs beyond it. I guess once it's reached the required temp you could turn it off for a while to save power and then plug it back in when you saw the temperature dropping, but I would advise against that. The sensors aren't always a good reflection of the temperature reached inside different objects/in the middle of stacks of things, and you want it as hot as possible to make sure every tiny pocket of air is as hot as it needs to be. Though of course that does make it a total nightmare to run in summer. No it doesn't, at least the model that was on sale a while back (and I don't think it's changed).

Yes, it does retain it's setting. I don't know if there is a time limit for how long the setting will be kept, but I've seen it retain the temp setting after a several hour power outage. I have two of these installed and they both returned to their set temps following a power outage.

I leave it on all night (about 10-11 hours run time per evening/night), so I guess that would be the equivalent. It has a button for low, one for medium, then both pressed for high with a dial that goes from 1-5. There is also a safe heat feature where it shuts off if the device overheats.

no. there is a key pad on the front of the unit so you can select the temperature that you would like. Its worked great for us so far. Good luck

Absolutely B, you can just put the temperature at whatever you went whenever you want and leave it that way.. does that help?

It's programmable, so you can simply make it turn itself off during the night. You can manually turn it off if you go on vacation. Otherwise, you can set the temperature as low as 60 degrees, although if you put it on economy, the temperature would have to drop 4 degrees before it would come back on.

Yes, it is a great feature in my opinion. You can always manually change the temperature, then at the time of the next "time period" in the schedule it will automatically return to programmed settings.

Starts at programed time. It comes on in the morning and at night at the time I have set it to come on. I don't know about the other answers here but I can set mine in the Winter to come on after the temperature drops 1 or even 2 degrees below the set point - this stops the thermostat from cycling on and off with just a very small change below the set point - great to be able to do this. You can do the same for the Summer time settings. I LOVE this thermostat.
