I am replacing a single stage GSHP with a two stage unit. The current controls include two Tekmar 420 boiler resets to run the HP and a Knight 80. the zones (5 heat, 2 cool on HP and 4 heat on Knight) are controled with three 336 zone pump managers. All zones have TNet4 therms, 541's and 544's. I would like to incorporate the new 406 house control to run the HP and need comfermation that it will "play well" with the 336 zone managers allowing to leave the therms and pumps wired as is. This would also cut cost significantly so I can splurge on a few of the new 557 therms to replace the 544's. Can one of you familier with Tekmar comment? rough drawing attached. Thanks
