The new Robertshaw® 9801i2 thermostat makes controlling your customers' comfort even easier. We've combined humidity and temperature control in one easy to install, easy to program thermostat. This versatile thermostat provides control over both humidification and dehumidification.
When used in conjunction with our 9025i outdoor sensor, the 9801i2 automatically controls indoor humidity levels maintaining optimal comfort while minimizing condensation on windows. Your customers will enjoy maximum comfort and energy savings and you will benefit from the time and effort saved by installing a single device that does the work of two. The new Setup Wizard allows you to spend 50% less time setting up the thermostat over competitive models. Everything is in plain language so there are no complicated codes or button combinations to memorize. The new 9801i2 is so user friendly it sets a higher standard in efficiency and simplicity for programmable thermostats. It is truly comfort made even easier.
When coupled to our outdoor sensor, the thermostat will automatically determine the optimal indoor humidity levels to minimize condensation on windows. A special humidity calibration feature allows for fine-tuning of the automatic sensing feature.
Note - dehumidification feature provides usually energized contact, deenergized on call for dehumidification and works only with HVAC systems with variable speed fans.
* The 9800i Series currently offers two display options - English or Spanish.

Comments about Robertshaw 9801i2 Programmable 1 Heat/1 Cool Thermostat, with Humidity Sensing:
Best to install the thermostst by an HVAC service man unless you understand wiring diagrams for the A/C unit and its controls. Mis-wiring could damage the thermostat. I traced all wiring prior to installation and the unit works exceedingly well. A humidifier will be installed this fall and will be controlled by the humidistat in this unit.

Comments about Robertshaw 9801i2 Programmable 1 Heat/1 Cool Thermostat, with Humidity Sensing:
Before making my purchase, I did extensive research on all stats/mfgs.
This is the only stat that allows internal, remote indoor and remote outdoor sensors.
Also the only stat that will allow the level of programmability with the internal/remote indoor sensor.
Using this stat with indoor remote sensor solved my 2-zone problem.
Simple install, intuitive user controls.
Highly recommended.

Comments about Robertshaw 9801i2 Programmable 1 Heat/1 Cool Thermostat, with Humidity Sensing:
We had to replace our broken thermostat and this was the second try. The first one was cheap and didn't keep an accurate temperature. This was a huge improvement. It installed easily and keeps a very accurate temperature. The vacation feature is great as you can set it to go back to normal programming at a set date/time. Definitely a great thermostat for a reasonable price.

Comments about Robertshaw 9801i2 Programmable 1 Heat/1 Cool Thermostat, with Humidity Sensing:
Display a little hard to read. Can't see it from across the room like I could with my previous thermostat. If this were improved, I think this thermostat might be perfect.
I got this product because it has an adjustable temperature differential, which is a wonderful thing. You can adjust how many degrees you want your furnace/ac to heat/cool. Goes from .5 1.5 2.0 2.5 and 3.
With my old thermostat, the differential was not adjustable and was set at 2 degrees. So it would go from being slightly cool in the room, to WAY too hot. 2 whole degrees is far too much. I was constantly jumping up to manually make the heat cut off.
It was even more annoying in the summer.
Now we can set the differential at 1.0 or 1,5 degrees. SO much better. Nice, constant temp.
Have not yet used the programming, but the menu is very easy to use.
Oh, I also wish you could set the temps in between whole numbers. Like 68.5 or 69.5. It only allows whole numbers. Oh well, I don't want to be too picky.

Very simple to install and program. I am using it in conjuction with indoor and outdoor sensors and they work very nicely together. The temperature and humidity levels seem to be much more comfortable since installing them.
