Honeywell Thermostat 2300B vs 2310B temp differences

[kansascats]

Lowes sells the 2310B for 40, HD sells the 2300B for 25.

Both seem to do about the same thing, the 2300 actually has a one button "HOLD" whereas the 2310 you have to remember or look-up what to do.

However, the 2310 seems to be more responsive -- meaning --

This AM.. it was 60.. both showed 60 at the start. The 2310 showed a warmer temp sooner than the 2300, but they did eventually both settle out at 69 (desired temp). At times, the 2310 would be 2 degrees higher (69 vs 67).

I really figured the temp sensor on these would be the same (same on all Honeywell's for that matter), but something does seem to be different. The 2300 is the one wired to the furnace now, the 2310 just sitting next to it.

Any thoughts on which is the "better" one? The 2310 just seems to be more sensitive, which in theory might suggest a smaller temperature swing range???

I think it is a crap shoot as to which is going to be more sensitive. You'd need a couple of more samples to be sure the difference you see is consistent to the models, not just normal variation in the making of the sensors.

The 2300 does not have the early start feature: Early Start Function - Adjusts the pre-heating/cooling of your home so you are comfortable at your programmed times

The two degree difference you saw may have been much less due to rounding. At say, 66 degrees, one could have been 65.4 and reading 65 while the other was 66.6 reading 67. Location and air currents between the two can make a difference also. Unless they were both mounted on the wall side by side. Pick the one that has the feature you like and don't drive yourself crazy. Both will work well.

2300B seems to heat well beyond the desired temp. Came in tonight and it felt "hot". It was running and reading 69, while the 2310 was at 71. I'm going with the 2310. It does not have the "hold" button but the "mode" button does a hold.
