Appendix

Thermal disinfection for preventing legionella infection causes

high return flow temperatures during the disinfection cycle (return flow temperature limita- tion suspended),

high storage temperatures after thermal disinfection has been concluded,

lime scale (possibly), which can have a negative effect on heat exchanger performance.

Note!

This function is not available when a storage tank thermostat is used.

Functions	WE		Configuration
Storage sensor SF1	ON		Co4 -> Fb00 = ON
Thermal disinfection	OFF		Co4 -> Fb08 = ON
