6. The timer for hot water production will only be available if the operating mode envisages hot water
production.
7. The timer function will only work once. If you want to use it again, you must re-set it.
8. The timer is deactivated if the unit is manually switched on before the timer start time.
9. If the relative function is activated (paragraph 8.3), the value of this parameter will be stored in the
memory and automatically reset after any possible voltage failure.
10. The default value for this function is “Off”.
After accessing the “Temp. timer” function, you can
set programmed variations of the water delivery set-
point (this set-point will depend on the currently ac-
tive operating mode). The function can be activated
or deactivated by clicking on the “Temp. timer” label;
click on the “Period 1” label to specify the time at
which the water delivery set-point is to be changed,
setting it to the value specified in the “WOT-heat 1”
parameter (which when clicked will display a numeric
keypad to change its value). Set “Period 2” with related
“WOT-heat 2” in the same way.
Click on the labels for the delivery temperature pa-
rameters to display a numeric keypad (with an indica-
tion of the range of permitted values) which you can
use to enter the required values.
