Hi all,
Some years ago Grundfos introduced Pump Plan, a two pump heating system with a wiring centre containing a relay, as an alternative to using the zone valves required by S-plan and Y-plan. This product has been discontinued for some time.
I can replace the dual-pump with two 15-50s or 15-60s but the dedicated wiring centre is no longer available. Can any kind soul provide me with one? Or suggest another wiring centre that contains the relay necessary to independently switch CH and HW, together with connection for the pump overrun?
Many thanks
