Having Viessman Vitodens 200-w 32kw installed. I’m expecting to then install low loss header and secondary pump for whole house. (Size / flow rate justifies this).
I’m looking for
1) confirmation that the secondary pump will be controlled via (something like) their EM-M1 controller. ‘Think’ this is true, but not def!! Inn know this has input from LLH sensor.
2) Forums suggest a Grundfos pump, but what ‘communication/data control’ must it have? I know Magna 3 has input for ‘delta t’ sensor, but is that required, or just a fully modulating pump? Which Grundfos pump ‘family’? 25-100 is the right size.
Much appreciated
