Is there any delay between when I select a new temperature and the HVAC coming on? Current Honeywell model may not respond for several minutes.

Yes it is a delay. But that is a good thing, because it help in prolonging your compressor, in cycling on and off. That is the reason for the delay

There is no delay at all unless you change it and then immediately change it again. There is a lockout - I don't remember the name they give it, but it is programmable. You set the interval at which the program can change to (I think) either 2 or 5 minutes. If you try to change the temperature a second time within that interval, the second change will not take place until after the interval has passed.

The default is a 5 minute delay between cycles. A 2 minute delay can be selected via a dip switch #3. Off (default) = 5 minute delay. On = 2 minute delay.

When you first program it, it takes a few minutes for the memory to work once programmed but once it gets going it does fine. When you change the temp manually it only takes a few seconds to kick in.

Whenever I manually override the current setting (bump it up to make the AC kick on) the display says "Wait" and it does take a while for it to kick on.

The programs are not fully different. You cannot set different times for each period for cooling and heating programs. E.g. with my old thermostat I could set Heating period start times at 6am, 12 pm, 4 pm and 10 pm, but for Cooling period at 7am, 11 am, 5 pm and 7pm. This is important for me since electricity rates are different for time of day where I live, but natural gas rates are the same, to in winter I do not care about time of day so much.With this thermostat, I will have to change times (e.g. reprogram the thermostat) twice a year. With old thermostat, I did not have to do this.

I called my provider (Customer Service). They said it would work. If they won't tell you ask for the supervisor. My Honeywell has worked fine for almost two years.

Same here, I've set the time delay to 0 (30s) to test. In my case the bathroom is dark when I enter so the sensitivity dial is supposed to be set all the way clockwise. When I had it all the way to the left the fan turned Off and then right back On after 2s...

Might be something wrong with your unit. Ours heats up in a matter of minutes

I had 2 units that exhibited the same symptom - 99 in the display. I called Honeywell and they really didn't have a solution other than to return them, which I did and bought another brand. My only thought was that Honeywell had a bad batch of the thermostats and Amazon got more than there fair share. Only Honeywell will know about the bad batch if they even look at ones that are returned. My guess is they won't unless there are thousands of units with the same failure.

Yes. There is a 5 minute delay. There maybe a switch to increase this, but I have not looked at the unit in a while.

Sorry - I have not as yet installed the thermostat. Honeywell product support should be able to answer your question.

I don't have the 9100U; for some reason Amazon keeps asking me about thermostats I don't have. Nevertheless, most any thermostat these days has something to prevent short cycling (a delay of 5 mins or so after the unit has turned off before it can be restarted by changing a thermostat setting).

I could be a replacement for an earlier model. Go to Honeywell and put in the model you have and you should be able to cross reference it.

Is this a new thermostat? If so, I'd return it. I have the identical unit and mine adjusts to at least 80. There is nothing in the instructions to explain why you would be having the problem. Also, Honeywell has a good website for instruction PDF downloads.

If you have an air vent close to the sensor, it will detect the change in temperature from the heater/AC airflow. One of my bathrooms has that issue. Try redirecting the airflow higher so it's not registered by the sensor.

I would say no. However a call to a HVAC (Honeywell) dealer may have the answer you are asking, or calling Honeywell Directly.But again i would say no it doesn't..

You could kill the power to your HVAC system temporarily and see if Honeywell emails you. Or open up the app after power is disabled and see what it does. I remember getting an email message every hour about no internet access to the stat. It depends how you setup the frequency of messages. I hope that helped

I noticed it takes a couple of seconds because it has to adjust to the new temp, but it could work like that as well. Hope this helps.

For sure it shouldn't take an hour. Mine heated up almost instantly. You may have your wires connected improperly.

Hi,If you change the mode to fan or dehumidify the current temp will display. Otherwise the temp shows the desired temp, rather than current temp.
