Free time switch program

The free time switch program can have an impact on the following functions:
• Forced charging of the buffer storage tank with the heat pump (operating line 475)
• D.h.w. circulating pump (operating line 772)
• Auxiliary functions 23, K13 (operating line 169)
• Additional pump kick for water / brine pump (operating line 427)
