Kumo Touch MHK2 RedLINK Wireless Thermostat & Receiver Kit

Like it better than hand held remote that came with unit. You also will need to buy their wifi hub to connect this thermostat. I believe this equipment is overpriced, but if you need wifi go for it

I was concerned that this product would be a waste of money, but needed it in order to disable the fan when my wall units hit the desired temperature. Installation is relatively easy, although disabling the fan for my specific units also required removing a resister. I feel like for the price of the units, these should be the standard controller and functionality should never require removing a resister, but now that I have these installed, I couldn't be happier.I love the UI and professional look of these units. Far more intuitive than the hand held remotes.

This review is intended for those considering upgrading from the older MHK1. There are several things to be aware of that disappoint in this unit when upgrading from the MHK1.PROSLooks much more modern than MHK1.Reasonably compact.Works very well for holding consistent temp.A wifi interface can be added for mobile/cloud/alexa control.Installer menus are a bit better than MHK1.CONSLooks and feels pretty cheap, and nowhere near the cost.Basic monochrome display.Not Apple homekit compatible.Is not compatible with accessories that show outdoor temp and humidity.After 10 seconds, the screen switches to only display room temp. You have to wake the display each time to see the set temp or anything else.Schedule doesn't allow for different times in heat or cool modes. Both modes must use the same schedule times. (MHK1 allowed this).When running a schedule and then adjusting the temp, it prompts you how long the temp hold should be for, defaulting to 1hr. It's a clunky process to set how long the temp hold should last. This is my biggest issue when coming from MHK1. It would be much better and easier if it just held the temp override until the next scheduled event.

Nice thermostat that permits control over cooling and heating remotely by cell phone or wi-fi. Works nicely and permits various programs. Still not as flexible and sophisticated as the Ecobee or Nest thermostats, however.Update: thermostat is not accurate. For example, if set for 65 degrees it permits the system to heat by as much as 4-5 degrees higher or 70-71 degrees. We have three of these devices and the same range occurs with each.

Many buy the MHK2 to get the temperature sensor away from their head unit, which may be on an exterior wall, up high, down low, etc. We paid for this expensive Redlink device and are not happy with its primary function: a controller. In short, it does a bad job. Mounted right next to the old thermostat, in addition to having placed a third thermometer, the MHK2 will reflect temperatures (not settings) that range in differential from +1 to +6 degree F. Calling Mitsubishi, they recommended reverting to the head unit's sensor, which gave more accurate results but still allowed the call for heat to stop up to 2F short of the setting. I expect Mitsubishi may not swap for another, given many complaints about these units, and I'll be eating >$500 (MHK2 and Kumo) to instead control Mitsubishi's hardware (which I have no complaints about) using an Ecobee, or other.

We had a 4-head Mitsubishi Mini Split system installed last Summer. It came with hand held remote controls for each unit. The larger unit in the living room was very accurate- the temperature in the room would stay within one degree of the temperature we set on the remote control. In the three bedrooms, however, we had to set the remotes to 77 or 78 degrees for the room to be at 72. And in the Winter, we set the remotes to the lowest heat setting (61) and the rooms would go up to 80 degrees! The reason this happens is that the bedroom units are a little oversized, even with the lowest btu available (6000). The actual thermostats are in the units themselves, so they do not accurately reflect the true temperature in the room. The living room unit is more accurate because it is perfectly sized (12,000 btu) for that space. The MHK2 thermostats can be placed on an interior wall, away from the units themselves. The units send a signal to the thermostats thru Red Link technology. The room temperature is monitored and controlled by the MHK2. It provides much better control than the hand held remotes. Now the temperature in each bedroom is within one degree of what we set on the MHK2. I highly recommend the MHK2 if you want better control of your Mini Split system. You can put them anywhere you'd like- no more having to use a hand held remote!

The accuracy of this thermostat is always off by 2-3 degrees. I have no idea what Mitshubishi is thinking and don't intend to find out I hope they improve and come up with a smart thermostat that works with the proprietary equipment they manufacture. Until then I'm stuck as I bought a house with the equipment and expensive to replace a unit. Here's my advice choose equipment other than Mitshubishi until they get it right with thermostats and other products that have smart capabilities.

Much more useful than the IR remote that came with the mini split. Temperature is measured at the MHK2 and is more stable. IR remote had to be exactily aimed and if it didn’t produce a beep, it didn’t program the mini split. MHK2 communicates 2 ways so you know what was programmed. Installation was a bit fidgety taking off the covers, but was otherwise do-able. Recommend this solution for any installation.
