Hi all,

First timer here. I have a existing boiler with 6 individual 007 pumps installed 2 are free the other are for 1 DHW and 3 baseboard, leaving 2 ready to go on the boiler manifold. Currently connected to a TACO SR506-EXP. I had the 1/2" Pex-Al-Pex installed and the floor poured. there are 3 loops in the floor along with the tekmar floor sensor. What I need to know is th ebest way to get boiler protection and also feed the radiant heat. Heres what I have for parts. I have a 4 way mixing valve with actuator and a Tekmar House control 371, 2 manual 3 way thermostatic misxing vales (1-3/4" Danfoss & 1 1" TACO), 3 Way Wirsbo TruFlow manifold. Can someone helpme to put the best solution together? Thanks.
