Tools and Hardware Reviews of Honeywell RTH230B 5-2 Day Programmable Thermostat
Customer Review: Wiring can be tricky
Summary: 4 Stars
I bought this after our county started giving $25 rebates toward programmable thermostats. My old digital (carrier) non-programmable thermostat had 5 wires. I hooked this one up with all 5 wires but found the A/C would not turn on, even after the 5 minute warm up. After reading an Amazon reviewer having a similar problem, I reinserted the RC/Rh jumper and disconnected the blue wire, taping it off with electrical tape. Works perfectly now! This is day two and I am experimenting with the default program mode, which is working fine.
I was also worried because the package said it does not work for multi-stage systems. I have a high efficiency gas furnace that is two stage, and it is working normally with this thermostat.
Customer Review: spend a little more
Summary: 2 Stars
We inherited this thermostat in our new house. We previously had one of the 7d programmable Honeywells. This one is a huge step down. The temperature swings drastically past the setpoint, both up and down. It's difficult to program. You have to pop the cover plate off to make any adjustments other than a quick up/down. We also miss the target feature where it learns the time your house takes to get to the setpoint and compensates.
This one will get banished to the garage shortly and we'll be investing in one of the better Honeywells. I'd suggest that you skip this one and either save your money on a basic model or spend a little more on the better units, especially if you value maintaining a constant temperature.
Customer Review: Works as advertised, Easy to install
Summary: 4 Stars
In an effort to save a few bones on the gas bill in the winter, I purchased this thermostat to replace an old nonprogrammable one. With minimal effort (1 screwdriver, 10 mins) I was able to replace the old one. You'll need to connect 4 or 5 wires from the wall to the new unit. Don't fret though, thermostat wires are colour coded!
Programming is simple (3 mins to fully program) and the unit allows for two groups of programs (monday-friday and sat-sun).
My only qualm with the product is the batteries shipped with it, they only lasted about a week before they needed to be replaced. I've put in a set of decent batteries and now all is good!
Customer Review: Great thermostat--lousy installation directions
Summary: 4 Stars
I installed this thermostat to control a gas furnace, following the wiring instructions. The instructions said to remove the jumper wire in the connection terminal if you had a two-wire control circuit. I did as instructed; the furnace came on but would not quit. After I played with the unit for several hours, my wife checked the Honeywell website, and finally found that the instructions there said that the jumper was mandatory for proper operation if you had a single transformer and a two wire system. I put the jumper back on and the thermostat has worked flawlessly since. The thermostat works really well, but the directions stink.Customer Review: great product for the price
Summary: 5 Stars
This product is a great deal for the price.
It is easy to install. It took about 30 to 45 minutes to complete the entire process and can definitely be done by anyone who can read and follow directions and also has some common sense.
My only suggestion would be to make sure that you have the smallest Phillips screwdrivers possible because some of the screws are quite small.
You will definitely save money on heating/cooling if you are replacing an existing non-digital thermostat. I am already turning the thermostat down to exactly 58 degrees at night and only up to 68 during the day.
