Cannot set min heat lower than 60F

I am very frustrated that I can not set the minimum heat lower than 60. We spend many cold months away and like to have our house set at 50. We are in New England so 60 is too high for no one being in the house. We would like to set it to 55 or 50 but 60 is the lowest it will go. Our NEST app works EXTREMELY well and allows for a minimum heat. The FGL External WIFI device is a big waste of money if app can’t have this lower temp feature.

Works well but needs support for Minimum Heat mode

Installed the WiFi remotes into our 36btu indoor Halcyon wall units, which took some time since it was my first time removing the covers from them, but went ok. I was able to get the remotes connected to the Wifi router easily, and the app was able to find them and register them. So far (only been a couple days) it’s working well. I especially like the fast feedback on the status of the units, like if someone manually changes the temp or mode with the IR remote, I can see the changes in the app. From reading the reviews I wasn’t surprised that the app doesn’t support Minimum Heat mode (temp below 60), but I was shocked to discover that after connecting the WiFi remotes, Minimum heat mode no longer works at all, even with the IR remote! This is a problem for a function hall that’s only used occasionally.
**Update 4 weeks later**
I added a star because after 4 weeks I haven’t had any problems and everything is working the way it should, managing 2 remote Halcyon 36k BTU systems. Also I found a work-around to the lack of support for temps below 60 degrees: Using the instructions in the installation manual, I recalibrated the thermostat 10 degrees lower. This resulted in set temp effectively at 50 while set to 60. The only downside is that you have to turn the heat up to 80 degrees to bring the interior up to 70.

Upgrade made the APP non functioning

The main reason we choose to put in the Fujitsu split system was because they had an App. I guess I should have investigated whether they had a working app. Since this latest upgrade NOTHING CONSISTENTLY WORKS. The company that installed the system changed the receivers in the split heads and that worked for a few months until this new release. The heating company doesn’t know why and offers no solution.
I also agree with the person who wants to lower their heat below 60. When no one is home 50-55 degrees to sufficient.
Why does this app, when it’s working, only show the temperature the device is set at. It should also give you the actual room temperature so you can see if the heat is actually on. We’ve purchased an Ecobee just to monitor room temperature. It would be so much better it Fujitsu would just interface with real WiFi thermostats.
Very Disappointed!
