I recently bought a home with an oil fired Biasi furnace that has a Hydrostat 3250-Plus attached. It uses an old analog round dial thermostat, and I'd like to replace it with a new digital (wifi) thermostat. The old thermostat only has two wires running to it (T and T), but the new one I bought requires a C wire. I went down to the furnace to see if there was an available terminal only to discover the Hydrostat. The directions for the hydrostat show the two 'T' connections, but not a 'C'. It has a C1 and C2, but the manual says these are for a circulator. I'm not great when it comes to wiring diagrams, and I'm at wits end trying to figure out where to go from here. I've included links to the manuals I've been able to find. If I can't connect the Honeywell wifi thermostat, any ideas for other options?
I believe its page 23 on the first one, as we have the Riello option.
