Digital Programmable thermostat for home - single pipe steam system
Thermostat controls only heat, no A/C.
I would like to replace my manual mercury thermostat for my home heating system. I have single pipe steam. Small home so I guess it is only one zone if that applies to this topic.
The thermostat cable that is used is using two wires going to the steam boiler. There seems to be more wires in the cable but not being used. I traced the cable that connects to the steam boiler and see that only two of the wires are actually being used. I am a bit hesitant in disconnecting the thermostat from the wall to see how many wires are connected to it but I would think there would only be two wires in the back of the thermostat. I don't really want to pull it from the wall until I am ready to replace it and have the new unit in hand. I will pull it from the wall if I have to in order to be sure I buy the proper thermostat.
There are so many available on Amazon I just have no idea what I am looking for when browsing.
I want one that I can program. Preferably one that has 7 days. I don't want one where it is only one program feature where a week of Mon-Fri is controlled by only one program. I would prefer that it can program all 7 days independently if possible.
I am thinking that I may want one which is WiFi capable but I am not sure until I see the diff in costs if it will be worth the extra money for it.
The problem I have also now is that the temp diff from what the manual therm is set at can vary up to 8-10 degrees before the boiler kicks on or off. So I either freeze from the cold before it kicks on or I die from the heat before it kicks off as it cycles. I believe there is a setting I can adjust but it is so old I really don't want to mess with it and just replace it. More important that I can program that continue to use this manual one.
When I browse on Amazon what should I be looking for so I know it will be compatible with my steam boiler system?
Thanks
