Set hot water temperature
Hot water from the steam/hot water boiler is mixed with some cold water before it is dispensed. Water
temperature at the hot water spout depends on the temperature and amount of the mixed-in cold
water. The temperature of the incoming water differs from place to place and possibly on season as
well. The amount of cold water inflow is related to the inflow pressure and can thus be adjusted by
changing the (outgoing) pressure of the steam/hot water boiler pump. Increasing the pump pressure
decreases the temperature at the spout and vice versa.
With incoming water temperature of approximately 10 °C (50 °F) and a steam/hot water boiler
temperature of 125 °C (257 °F) and a pump pressure of 8.5 Bar, the water at the hot water spout is
approximately 95 °C (203 °F).
Procedure
1. Wait for the machine to be co
mpletely warmed up: at least “ON” and heating for 25 minutes and
used (as if) to make coffee and dispense hot water at least 5 times over the last 5 minutes.
2. Get the main controller in adjusting mode (to get a long lasting flow of hot water):
Touchpad
: press-hold the upper button on the left hand touchpad for 6 seconds;
Bastone
: press-hold the programming button below the left group lever for 6 seconds.
3. Within 5 seconds, activate water dispensing by shortly pressing the hot water lever down. Water
will start flowing.
Note!
Work swiftly: the boiler quickly empties when hot water is dispensed continuously.
4. Measure the temperature of the outflowing water with a quick-response temperature sensor* and
de-activate the hot water by shortly pressing the lever again. The water temperature should be
around 95 °C (203 °F).
5. See Figure 12. If the temperature is too low: decrease pump pressure of the steam/hot water
boiler pump (turn set screw counter-clockwise).
If the temperature is too high: increase pump pressure (turn set screw clockwise).
Figure 12. Adjust hot water temperature by changing the pump pressure of the steam boiler pump.
6. After adjusting the pump pressure, measure the temperature again.
7. When the required temperature is reached, re-set the hot water timer to the desired amount of
water (see section “program hot water timer”).
8. When the required temperature cannot be reached, the fixed restrictor in the mixblock can be
exchanged for one with a larger diameter (to obtain a lower temperature at equal pump pressure)
or smaller diameter (to obtain a higher temperature). Contact a qualified technician for this.
*
If you do not have a quick response temperature sensor, decrease the pump pressure until
boiling water is flowing from the spout (flow will sputter instead of dispensing a calm flow). Then
increase the pump pressure a little until a calm flow is obtained.
