The controller calculates the temperature difference between solid fuel boiler sen-
sor S1 and store sensor S2. If the difference is larger than or identical to the adjust-
ed switch-on temperature difference and if the adjusted minimum temperature of
the solid fuel boiler, the pump (R1) will be switched on and the store will be loaded
until the switch-off temperature difference or the maximum store temperature is
reached.
Heat exchange control to an existent store via an additional pump (R2) can be
carried out with another temperature differential function (S3 heat source/S4 heat
sink).
