Buffer Service Settings
Once the heat buffer (36) has been loaded, the regulator stops the pump (6) and enters
SUPERVISION mode. The pump (6) starts in-spite of loaded buffer (36) once the boiler
temperature has exceeded the preset value by 10 C. Pumps (12) and (13) are stopped, and servo
(14) is closed once the buffer temperature has dropped to below
Min. buffer temp.
