Hello All, I purchased a Fahrenheit hydronic baseboard heat along with a Marley T1 / T2 thermostat that installs at one end of the baseboard heat. The question that I have is how to properly wire this unit. When I purchased the unit I also purchased 12/3 wire and a 20 amp double pole breaker. The thermostat has 2 red 2 black and a ground wire The baseboard heat has 1 red 1 black and a ground wire. The wiring diagram on the thermostat shows L1 and L2 as black wires and the reds going to the heat. If I understand this correctly I should take my black from the power in to black of thermostat.....the red power to the other black on the thermostat. The red wire of the thermostat to red wire to the red wire of the heater The other red wire to the black wire of the heater Wire nut all of the ground wires together including the white wire from the 10/3 Is this correct?
