in THE MAIN WALL
I'm installing a Buderus tomorrow mourning, and need some help with the wiring. I spoke with Buderus tech support earlier about wiring, but I'm still confused about zoning. This system has for zones, I'm confused about wiring with the Logamatic R 2107. Tech support mentioned I needed a isolation relay for the circulator. Could someone please tell me what field wiring I'll have to do between the Logomatic, the 8148E and the isolation relay(name of relay?) Thanks for any held or references

    The logimatic can handle zones BUT if you have an indirect we've used a separate circ. pipe the indirect circ to the DHW term on the logamatic control, then power a switching relay or zone control board from the Heat termials on the Logimatic. When the DHW call the power is shut down to the haet zones and powers the DHW circ, when DHW is satisfied power is sent back to the zone control and heat is on. Just remember your flo check on the DHW line.
