I would like to install a new thermostat on my second floor of my steam oil heating system.
Few questions for you.
1. How difficult is to connect the wiring to the boiler. Can I do it myself? Is it two wires that just need to be connected to two screews or is it more complicated? The current thermostats that are connected to the furnace are all 2 wires.
2. What kind of a wire I need to buy so that I can run it from the thermostat to the boiler?
