I think I broke the HVAC system

I have been babysitting for the same family for a while now.

They are a good family in addition to I legitimately respect them a lot.

They are always traveling so I get to spend a lot of time with their kids. They have 2 kids under 2 so it can be a handful sometimes, even though I legitimately do care about hanging out with them because they are so cute. However, I think that I might have broken their HVAC idea the last time I was over at their house. They have a valuable HVAC idea with a smart thermostat in addition to I don’t think how to use it at all. I was legitimately distraught to call them in addition to tell them about the HVAC idea because I think that HVAC systems can be legitimately luxurious to update. However, they weren’t aggravated at all in addition to said they would take a look at the HVAC idea when they got back. Turns out I did do something wrong when I was changing the temperature of the thermostat that caused the HVAC idea to stop working. I knew that I was going to have to be more careful next time I stayed over there… Well, the genuinely next month I did the same thing to their thermostat in addition to now I am distraught that they are going to fire me. I legitimately hope they don’t because I care about working for them in addition to the money is great!
