Change boiler temperatures
The factory set operational temperatures of the boilers are 93 °C (coffee) and 125 °C (steam) (199 °F
and 257 °F) respectively. 125 °C is equivalent to approximately 1.35 Bar steam overpressure.
Switch boiler temperatures with Störk ST25-Eco controllers
Your machine is equipped with Störk ST25-Eco controllers which allow you to easily change the
temperature of the corresponding boiler to a second (lower) setpoint. This way you can save energy
during the night or set a coffee-
boiler on “stand-by” during slow periods while preserving a relatively
short start-up time.
Figure 11. The Störk ST25-Eco controller. (Left) The lit indicator dot signifies that the heating element
is activated. (Right) the controller in ECO-mode.
Factory standard is that the second setpoint for a steam-boiler controller is 70 °C (158 °F) and for a
coffee-boiler controller 50 °C (122 °F), see Table 3. While the second setpoint is active, the display will
show
“Eco” instead of the actual temperature in the boiler.

Table 3. Factory set temperatures in the Spirit and way to switch between modes.
Procedure to change from operational to Eco-mode
1. Press-hold the SET/ECO
button (for approximately 6 seconds) until the display changes to “Eco”.
Procedure to return from Eco- to operational mode
1. Press-hold the SET/ECO button (for approximately 6 seconds) until the display shows a
temperature value.
NB:
The start-up mode of the
controller is “operational mode”. When power is discontinued for a
short time (mains switch to “OFF” and then back to “ON”), all controllers will start up in operational
mode simultaneously. A momentary power-failure will have the same result.
Procedure to adjust the operational boiler temperature
1. Make sure that the operational temperature is active (a temperature value is visible).
2. Press-hold the SET/ECO button. The operational temperature is now displayed.
3. While holding the SET/ECO button pressed and before the controller switches to Eco-mode, the
and
buttons are used to increase and decrease the temperature.
4. Releasing all buttons will enforce the newly set temperature.
The operational temperatures can be set within the following ranges:
•
Steam boiler: 0-130 °C (32-266 °F).
•
Coffee boiler: 0-100 °C (32-212 °F).
