Unit looks well built and was well packed for shipping. I’ll update my review when I’ve installed.

The product works great, we had a few questions about the wiring and the technician on the phone was able to answer all our questions and even offered to wait on the line while we wired up the thermostat to make sure everything worked correctly.

Wi-Fi Fan Coil Thermostat

We switch between burning pellets, cord wood, or coal depending on price fluctuations. The build quality is excellent. Nothing else on the market even competes.

They created a custom Stat for me. Works great and looks great. Very happy.

This is to replace the old Honeywell T6575D. It has input 120v so I was not able to switch to Nest but I wanted a smart thermostat. Unfortunately there are not many options on the market. I was a little skeptic and worried when I put order around Christmas time and had not heard from Mbtek for a long time. The review on website mentioned the long waiting time. The good thing is I got reply after I sent email asking about the order status. Around mid April, I finally got noticed it was shipped out. About installation, it was simpler than I thought. It took me several days to think about wiring and to compare the wiring on old thermostat to this one. There are 8 wires from the wall and I connected them all to the new thermostat. Wire diagram is helpful and the reminder of external jumper between the L and com line is absolutely necessary. I did not use the wire gauge included, which was hard to cut. I had some solid copper 18 gauge left. I did a bit research and concluded it will work fine. A wall plate is included in the package and I appreciate their consideration. I checked the setting following the video posted under other review but I haven’t tried the app yet. I am quite happy with the display and hope it will function well in summer with good control of fan.

Waited several months for delivery of 3.5T unit due to shipping issues and COVID lockdowns.
Allen and others at MBTek were patient and as helpful as they could be with something outside their control.
3/4 of my energy bill is for heating between Oct and April. Hoping for a slight overall reduction - it'll depend on future gas prices.

Unit arrived mid April when my radiant floor system goes dormant until Oct. Lots of time for installation!

Will update later when it's actually working.
Getting Inflation Reduction Act grants is extremely difficult - there is no local contractor prepared to take on this install so it's a DIY!

Everything arrive safely. Very nice boiler.
