Answer: 
Yes, you can manually set the temperature, then press the hold button to hold it on whatever temperature you want at the time. If you don't press the hold button, then it will go back to its programmed setpoints automatically after I think 30 minutes or so.
I'm sure the newer model is outstanding compared to this one.

Answer: 
There are 2 ways to override the schedule in the RTH221.
The first is on a temporary basis. To temporarily override the schedule, simply press the up or down arrow until the desired temperature is displayed. The word temporary will appear on the display and the program period will flash to indicate that the current period has been overridden. This "temporary" setting will be used until the next Read More

The first is on a temporary basis. To temporarily override the schedule, simply press the up or down arrow until the desired temperature is displayed. The word temporary will appear on the display and the program period will flash to indicate that the current period has been overridden. This "temporary" setting will be used until the next scheduled period begins.
The second way to override the schedule is a Permanent Override of Schedule. To permanently ignore the schedule press the up or down arrow until the desired temperature is displayed. Then press the HOLD button to maintain the new temperature indefinitely. The word HOLD will appear on the display.
To cancel either the temporary or permanent override of the schedule, simply press the RUN button and the thermostat will return to the previously schedule program settings. Read Less

Answer: 
Hi Rachel, Yes it does have an manual override...simply press the up arrow to increase temp or down to lower. I see you live in Portland as do I and certainly understand the climate changes we are having these past weeks. Re-read the manual for how long the override can last. Stay warm.

Rated 4.7 out of 5 by 21 reviewers.
Rated 5.0 out of 5.0 by simple and inexpensive If you want a non programable thermostat then this is the one to get. Simple controls. Simple installation. Inexpensive. Two AAA batteries required (not provided). October 20, 2012
Rated 5.0 out of 5.0 by great value... no brainer For $20 this is a no-brainer if you simply are upgrading from your old-school thermostat. Installation - easy Programming - easy Batteries - swap like every six months Savings - we have a small house and have noticed a noteworthy savings in less than a year. Con - My friends and I have all noticed that at 4AM, the furnace cooks us - if you look at the thermostat it says 74! We turn it down to 68 at 11PM and up to 72 at 4:30AM. It might be that the bedroom doors are closed??? Somehow it over heats the house during that time period. We are upgrading to the 7 day programmable - we want to be spoiled! February 14, 2010
Rated 4.0 out of 5.0 by Quick Fix for Old Mercury Thermostat Installation - 4/5 - Incredibly easy. The wiring bracket is a really thin plastic that could break easy if too much pressure were to be applied. The directions were very clear and easy to follow. The wall mount is great; the thermostat sits off the wall only about an inch. Programming - 4/5 - Incredibly easy. Basically there are four time slots during the day that can be programmed. The time slots are predefined by default, but you have complete control over the time slots and the running temperature during said time slot. This model does not show the programmed temperature on the main display, only the current ambient temperature which may cause some unnecessary adjustments. Overall - 4/5 - This is a great upgrade from an old mercury based or broken thermostat. The programming options are sure to improve your electric bill from the moment installation is complete.

Rated 4.0 out of 5.0 by seemed nice... no for me I was really excited when these arrived. They appeared simple and easy to install. Unfortunately, when I took my old themostat off I had a W, R, and B wire. The directions told me to tape off the B wire since this model does not use a B wire. Unfortunately my furnace doesn't turn on without the B wire hoked up. I returned the thermostat. February 2, 2013
Rated 5.0 out of 5.0 by Well satisfied Thermostat installed easily. I wasn't sure about the wiring configuration so I placed a call to Honeywell customer service. Was well satisfied with the response. Wired it up as directed, installed 3 AAA batteries and it worked the first time. The factory default settings were about right so didn't even need to reprogram. February 10, 2013
Rated 4.0 out of 5.0 by Get the newer model if you need to. Since this product was replaced with a newer model, for practically the same price, I don't see how you could possibly go wrong. If the new model is anything like this one, you're good to go. This one has been very reliable. January 12, 2014
Rated 4.0 out of 5.0 by Simple and effective Extremely good price for this product although not as detailed as the 5-2, 5-1-1 thermostats; it is a quick fix and easy to mount to the controls. LED display is efficient and controls are easy to use. Temperatures are always +/- 1degree farenheit of what you program it before the central air activates to adjust the temperature. June 22, 2009
Rated 5.0 out of 5.0 by Honeywell Basic Programmable Thermostat RTH221B We have used this thermostat for about a year now and we love it! It is very accurate with the temperature settings, easy to program and a wonderful value. Also, there is no long heater-element delay in getting it to work--it starts up very quickly--a real blessing if you have to change the battery at 3:00 a.m.!!! I highly recommend this thermostat!
