    Glad you got if figured out

    You'll still need to tweak the Tekmar control to suit your comfort level and outdoor temps.

          Who's idea was it to add the jumper from L2 to #3 on the R845A?

            Me. How else would you get the HOT to get to the pump? Otherwise 3 and 4 are just connected to each other with the relay. Thes nothing there 120 or 24 volts without adding it somehow Also the wiring that i drew is off. The black actually goes to the L1 which says HOT on teh shcematics from honeywell and the white goes to the L2. dunno why they dont go in order 1,2,3,4,5,6, accross the bottom.

              Excellent job, Jeff

              No where in the wiring schematics do they show that jumper but you managed to figure it out. See?, you knew what you were doing all along

                You had me scared there for a second. Well i have alot of knowledge in automotive electrical and i dabble a little in home wiring so i know how circuits should work. But this one had me stumped. I think its all that A/C current stuff. Im set to think on D/C so it took me a few tries. But i knew the 3 and 4 werent fed by anything. (i used a volt meter to be sure) so i figured the jumper had to be done.

                But thats correct?
