I need to replace a heating mixer with outdoor reset panel and the WC8 or WC 32 is being considered.
One of the main stumbling blocks I have incurred so far is running a capacitor run pump with variable speeds.
One pump control for the circulating pump would be easy with an opto-isolated 120vac output relay. Should be the easy one.
The other control would be using an analogue output and hopefully be opto-isolated into a triac capable of driving these grundfos pumps.
Off hand I would say these are 1/16 hp or 1/24 hp capacitor run variety typical of hydronic heating systems.
Has anybody come across ready made relays that do this function? Analogue (0-5,9,10vdc to 0-120vac)
