Need to 240v power return heat from accum relay from Barn relay
Accumulator pump control Jan 2023
Degrees = Alt-Shift-8 °
LH Accum pump controlled by lower middle cylinder thermostat when less than 60° returns heat from accumulator. Pumps into bottom of accumulator
RH Accum pump runs when over temp alarm shows (more than 78°) ie when too hot leds lit, it pumps towards the right, ie from accum bottom to boiler bottom
