Anti-Legionella function
Anti-Legionella function is designed for thermal “disinfection” of hot water storage tanks,
primarily against Legionella bacteria.
When this function is ON, the hot water storage tank heats up to at least 65°C once in a week,
at a preset time on a preset day. Heating is switched off either when this temperature is
reached, or after two hours from switching this function on, disregarded of the temperature.

ThSt on
....................... Switching on thermal store heating on the User level.
T comfort (°C)
............ Desired temperature in Comfort mode.
T setback (°C)
............ Desired temperature in Setback mode.
During a day, the controller switches the desired thermal store temperature by the preset time
schedule.
The real desired thermal store temperature is the maximum of all demands from zones (heating
zones, thermal store zone, demands from universal functions...).
2.11. DHW recirculation settings
DHW recirculation and its time program settings on the User level. When recirculation is on, it
is performed following the time schedule set for each day. For this period, circulation time and
idle time of the circulation pump can be set if its continuous operation is not desired.

................................ Recirculation switched on..
circ time (min)
............ Circulation pump running time setting (pump is running)
idle time (min)
............ Circulation pump running time setting (pump is idle).
User can set up separate days when recirculation is on.
2.12. Statistics
HP statistics is displayed here (number of compressor starts and operating time) and statistics
of DHW and auxiliary source operating time.
