Midea Follow Me Function

[Raymond Freedman]

Remotesignal-receiving function

There is the signal receiver for the wireless remote controller on the KJR-29B. You can use the wireless remote controller to control the air-conditioner through the wired remote controller when the system has been powered on.

Notes: The wired controller will not receive the swing controlling instruction. For the indoor unit with swinging function, you can directly use the remote controller to control swinging through the display panel of the indoor unit, or use the swing button on the wired remote controller to control the indoor unit for swinging.

ON/OFF Button

Press the ON/OFF button to control the indoor unit on and off status. When the unit is turned off, press the ON/OFF button, the unit will be turned on and the operating icon lights up. When the unit is turned on, press the ON/OFF button, the unit will be turned off and the operating icon lights off.

Clock setting

Long press the timer/clock setting button for 3 seconds, and then enter into the clock setting status. The hour position of the clock will flash, and can press Temp setting buttons to adjust the hour value. After finish the hour setting, press left button or right button to switch to minute position setting, then the minute position will flash, press Temp setting buttons to adjust the minute value. After finish the clock setting, press the button or wait for 5seconds to confirm and exit the setting state.

Wired controller locking

Press the temperature adjusting UP and DOWN buttons simultaneously, the wired controller enters into locking state, and the locking icon will be lighted up. Under the locking state, the wired controller will not respond to buttons by pressing and the control instruction from the wireless remote controller. Simultaneously press temperature adjusting buttons again can cancel the locking state.

Air filter cleaning reminding function

The wired controller records the total running time of the indoor unit, when the accumulated running time reaches the pre-set value, air filter cleaning reminding icon will be lighted up, to remind that the air filter of the indoor unit needs to be cleaned. Long press left button for 3 seconds, and clear the reminding icon and the wired controller will re-accumulate the total running time of the indoor unit.

Notes: The default setting value of reminding function is 2500 hours, and it can change to be 1250 hours, 5000 hours or 10000 hours. The setting methods please refer to the installation manual.

Swing Function

If the indoor unit supports swing function, press the right button to adjust the air outlet direction of the indoor unit. Long press this button for 3 seconds can turn on or turn off the auto-swing function. When the auto-swing Control system function is turned on, the swing icon will be lighted up.

When the system is running and the operating mode is AUTO. COOL or HEAT, press the left button will activate the Follow Me function. Press left button again will cancel follow me function. When the operating mode is changed, and then will cancel this function as well. When the Follow Me function is activated, the icon will be light up, and the wired controller will display room temperature read from the local sensor, and transmit the temperature value to the indoor unit every 3 minutes.

Connect two terminals of embedded 4-core shielding wire with the switching wires of wired remote controller and signal receiving board. Make sure the sequence of 4 terminals (A/B/C/D) should correspond to the wire sequence of signal switching wires (A/B/C/D).

Avoid water enters into the wired controller, use trap and putty to seal the connectors of wires during wiring installation. When under installation, reserve a certain length of the connecting wire for convenient to take down the wired controller while during maintenance.

The MHK sensors are easy to install. You just need a philips driver to remove a couple screws to access the wiring connector to connect the wireless receiver. It really helps to stabilize things. The internal "room"/return air temp sensor is very prone to short cycling depending on the install, and air currents in the room. Before I had mine on my FH09 I could lay in bed listening to the compressor hunt, now it just settles into a steady capacity. (Note, don't wall hang the outdoor unit on a bedroom wall. Even though it seems silent when you stand beside it, there are vibration harmonics transmitted to the houses structure that get annoying.)

Personally I try and avoid wifi connected HVAC since it's likely to be obsolete due to changing standards long before the equipment service life is up. The MHK1/2 use the Standalone honeywell redlink protocol which doesn't have any external dependencies (like your wifi router).

Also, note the I-See sensor doesn't help with temperature feedback. All it does is help point the vanes toward or away from people/hot/cold spots, and act as an occupancy sensor. After playing with mine for a bit I disabled it due to the slight noise it makes when in a quiet room. It actually seems a bit gimmicky except for maybe the occupancy function which I don't use.

I do understand that the I-sensor is just for figuring out if there are people in the room, and/or where they are. I thought that by trying to avoid the people it would somehow spread the heat around more evenly? Anyway that wasn't the case. At this point I am starting to think the I-sensor is more of a marketing gimmick.

I am also not too interested in WiFi controls. Had a couple WiFi heater/AC units in the past, and after initially playing around with controlling them remotely, the novelty wore off and found myself just adjusting them directly. I could see how this would be useful for a second home or some other scenario.

Does Mitsubishi not have the follow me feature on the remote? Both my Midea and Gree have it where it uses the remote as the temp sensor. It

constantly transmits the temperature from the remote to the unit. Works awesome as it bypasses the units sensor. I placed mine on the wall where a traditional thermostat would go. It perfectly maintains the temperature on the remote.

I think the issue might be partially that it's IR so line of site, and one way (if I change the setpoint on my MHK the IR remote doesn't reflect the change, but the MHK will reflect an IR remote change.

If they used a RF remote then you could have, realtime space sensor feedback, two way comms and non-line of sight (like the MHK).

Right. I think the remote could still serve as a sensor, just sending the temperature info to the cassette.

Anyhow - there are plenty of simple engineering solutions that would work. I guess Mitsubishi has their marketing strategies and they must not care about this as much.

You can use Kumo cloud and the wireless sensor/reciever, it's less than the MHK's, same install, and you can still over-ride with the remote. Josh is right that the remote is one-way only, so it doesn't know if the unit is on/off or whatever, but as soon as you turn it on, it will over-ride the Kumo, but it's still using the remote sensor. I'm very happy with mine.

Its crazy that Mitsubishi makes you buy some few hundred dollar accessory for that feature. Even the $700 Pioneers have the follow me feature. They use RF not IR for communication as well. My Midea remote doesn't have a IR lens and will work without even pointing at the unit.

By the way - a question comes to mind: if you have the Kumo cloud interface with an external sensor, and you go to use the original remote to change something, will it still use the external sensor for feedback? Or will it revert back to the built-in sensor? This is important, because you don't want to always have to make your adjustments with your phone.

Also the MHK2 is available on ebay for $180. I spoke with a Mitsubishi tech rep, and it sounds like with the MHK2 and Kumo cloud can also be run together (connected piggy-back), if one were to get the MHK2, and later want to upgrade to cloud connectivity.

I have tried a number of ways of running these and the conclusion I've come to is get a thermostat interface module and connect your own thermostat. It is still expensive but at least now you are outside of Mitsubishi land and you have a lot more options. Their thermostat module is actually pretty nice when connected to a two stage thermostat. Even better if you go with a thermostat that has multi speed fan control and wire in all the fan stages.

Just found this thread, it deals somewhat with the same issue as a question I just posted. But my client has already sprung for the costly MHK2 and it can't seem to adequately control its mini-ducted unit (sez-kd09na4). It seems content with an ambient temperature (as shown on its own display) up to 4 degrees different from the setpoint. How can you configure the MHK2 to be the boss? It's already set to "sense temp remotely" and I'm wondering if there are other settings onboard the main unit that are overriding the remote.
