I have a split level house that has 3 hot water heating zones that run on a single oil burning boiler; One of the zones is for an exterior greenhouse, which is adjacent to the outside of my house. The circulator for the greenhouse zone turns on using a manual switch, and the temperature in the greenhouse is controlled by automatic ventilation.
We plan to remove the greenhouse entirely.
We decided to disconnect the greenhouse supply and return lines, but make use of the existing system by rerouting it to our basement, which previously had no heat. Now I am trying to convert the manual switch for the circulator into a thermostat controlled zone. I understand that I need to install a relay switch and connect that to the boiler, but I am at a loss for what time of switch/thermostat combination I should use, and how to install it.
Can anyone point me in the right direction? Much appreciated.
