LH Accum pump controlled by lower middle cylinder thermostat when less than 60\u00b0 returns heat from accumulator. Pumps into bottom of accumulator<\/p>\n\n\n\n

RH Accum pump runs when over temp alarm shows (more than 78\u00b0) ie when too hot leds lit, it pumps towards the right, ie from accum bottom to boiler bottom<\/p>\n\n\n\n
