It has been a long time since I have had a basic dial control unit to run my central heating plus a/c method unit. I have had a smart control unit for the last few years plus before that a official digital control unit. Both are not as easy plus easy to use as the original dial control units. I miss things being easy plus basic plus is the way I really want things when running my central heating plus a/c method unit. The way of the smart control unit is just a little too complex for my tastes. I am thinking about going shopping to see if I can find a dial control unit for sale to replace the smart control unit plus just go back to the basics. I know that a dial control unit is totally old plus not brand up-to-date plus up-to-date. But I really want my old dial control unit back! Had it not broken, I would have still had my old dial control unit to this day. But what I am going to do is just hope that I can find a dial control unit for sale somewhere plus just install the thing myself. I will not need the services of a heating plus a/c company to send out a certified heating plus cooling specialist to install an old dial control unit! I will look online plus see if I can find a great old dial control unit. I know that somewhere will have a dial control unit for sale. Even if it is a used 1, however as long as it works is all I care about. I am going back to the old ways!
