Specification of a reference value for the circulation.
If the temperature at the circulation sensor TWZ
drops below the reference value minus hysteresis,
the circulation pump CIRCU is activated.

11.18. Legionella protection (LEGIO option)
A legionella protection function can be programmed using the special time program on the control module.
If the legionella protection function is active, i.e. parameter (05-014) does not equal 0 and there is an enable from
the time program, the output is active for circulating the tank.
If the LegioSoll reference temperature set in the special time program is reached, the attempt is made to hold it for the
holding time set by parameter (05-043).
Legionella enable at 60 °C, 59 °C and lower = OFF
