Caution:
Standard pump: Set AC!
High-efficiency pump: Set HE!
External consumer (e.g. 230 V relay): Set AC pump type.
9.3.3 Solid fuel boiler
742.892 | 11.50
Performs temperature-dependent switching of an output for heating
a storage tank using an oil or gas burner. The function can be time
restricted.
Temperature control: If the temperature in the storage tank falls below
the value, then the external heating is switched on until the
T
on
perature is reached.
Time restriction: The function is executed when the current time lies
within one of 3 configurable time windows.

Controls a pump in order to heat a storage tank using a solid fuel boiler.
The pump is switched on when all of the following conditions are satis-
fied at the same time:
• The temperature difference between the solid fuel boiler and the
storage tank exceeds
• The solid fuel boiler temperature lies above the min. solid fuel boiler
temperature.
• The storage tank temperature lies below the max. storage tank
temperature.
The pump is switched off when one the following conditions is satisfied:
• The temperature difference between the solid fuel boiler and the
storage tank drops below
• The solid fuel boiler temperature drops below the min. solid fuel
boiler temperature.
• The storage tank temperature reaches the max. storage tank tem-
perature.
Speed control of the pump can be activated as required. The loading
strategy of the speed control system attempts to regulate the tempera-
ture of the solid fuel boiler to match the control target that has been set.
The control target should be at least 10 K above the minimum tempera-
ture of the solid fuel boiler.
