I have a chromalox canada boiler model EDB-2. Recently I purchased a wireless honeywell transponder and thermostat, and am trying to install them. I currently have
R wires but am missing a common ground
C wire, and am unsure where to connect it. I have 18/3 and 18/5 spare wires.
I've enclosed photos of the inside of the boiler. The LV terminals are numbered T1, T2 and 1-5.
An HVAC consultant was able to supply power to the honeywell transponder. Unfortunately when we attempted to use the thermostat, the transponder lost power. The HVAC consultant felt that the boiler could not supply sufficient power.
So how can I connect the transponder to the boiler?
