Store loading via solid fuel boiler and return preheating
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.
With another temperature differential function (S3 heat source / S4 heat sink)
return preheating (heating circuit backup) is possible via a valve (R2).
