* For 2 minutes, the maximum value, then the base value stated in brackets.
** Time needed from beginning of draining in order to achieve a temperature increase of 40K to the hot water outlet of the device based on the
CH hot water flow.
*** The maximum CH power is set in the factory. For the set value see the parameter list (par. 7.2 ).
Also see par. 7.3 Setting CH power.
