2.1 Profile choice
The first step to start the session is to choose a profile. Depending on the controller
model there is a choice of a steam bath, dry sauna, infrared sauna, wet sauna and a
ventilation profile. After selecting a dry sauna, depending on the temperature and time, the
heater will be turned on/off, with IR sauna infrared heaters, and for steam bath a steam
generator. For ventilation, operation time of the fan can be determined.
2.2 Session temperature
The next step is to determine the temperature. In the case of dry sauna it may be 3 -
11
o
C , for steam bath 2 -5
o
C, wet sauna 3 -65
o
C, and for IR sauna 3 -6
o

2.3 A justing the power of ra iators
ZXX CPIR controllers allow you to control the power of radiators in 5 stages
(1-3 % 2-4 % 3-6 % 4-8 % 5-1 % power). In these versions, temperature control is not
possible, and its maximum value does not exceed 7 oC. Radiators can be divided into two
separate groups, with the option of setting two different or the same power values.
2.4 Session time
The next step, sets operation time of the sauna session, it is counted from the moment
in which the heater, steam generators or infrared heater are started. First, you have to set
the number of hours, after pressing OK button, determine the number of minutes. When
determining the time, keep in mind the sauna’s heat-up time. Session time can be a
maximum of 2 hours.

FFES- FABRYCKI FUTURE ELECTRONIC SOLUTIONS 4.2 21 EN

2.5 Power of vaporizer
This stage is available only for the sauna with a combi heater. At this stage, power of
vaporizer is determined. Power of vaporizer is the percentage of the vaporizer’s time cycle,
which lasts for 2 minutes.
Example: The set value is 10%, in this case the vaporizer runs for 12 seconds. And for the
remaining time of 10 seconds it will be turned off. This cycle takes place in a loop that ends
with the end of the session.
2.6 Aromatherapy
Aromatherapy intensity regulation is performed similarly to the evaporator power
regulation. The only difference is that in the menu we can adjust the cycle time for
aromatherapy. The dispenser cycle can range from 1 to 1 minutes.
Aromatherapy example for settings: cycle time 5 min, evaporator power value 1 %
2.7 Ventilation
The final step in the transition into operation mode is to provide time of ventilation,
which will be launched after finished session. When you touch the button to increase the
value, minutes also change, and after reaching 59 minutes also hours. Ventilation time
cannot be longer than 2 hours. When choosing : , ventilation will not start.
For wet sauna, auto drying mode is available, in which after finished session, the heater
is activated for 15 minutes at the set temperature of 75 ° C. The user at this stage can select
it or abandon it.

2.8 Operation mo e
The transition to operation mode switches on the heater, the steam generator or
infrared heaters. After reaching the set temperature, the heater is turned off when the
temperature falls by the hysteresis value, the device is switched on again. In this mode, the
controller controls the temperature, counting down the time set by the user, making sure
that the temperature in the sauna does not exceed the allowable temperature. It also
controls the status of the water level in the case of Combi heater, and displays the current
time. Additionally, in this mode, when you touch the up arrow, you can turn on or off light.

format. After losing power, the clock is reset and returns to : .
2.9.3 Delay
The controller is equipped with a delay function, which allows you to activate the sauna
at a specified time and with the parameters set by the user. Similarly as in a timer, the
number of hours is first set after which the sauna is going to activate, and then the minutes.
In the next steps, a profile is selected, as well as session temperature, session time and
possible ventilation time, and power of the dispenser. After finishing this step, the
controller calculates the time for the sauna to activate, and presents it on the display, and
then it switches off. Starting the driver again, or interrupting the above mentioned process,
resets the delay time.
2.9.4 Hysteresis
Hysteresis is an adjustable parameter, can range from 1-6 °C. This parameter determines
the drop in temperature at which the heat device turns on again.
Example: The set temperature is 90 °C, after reaching this temperature the heater in the
sauna switches off. For a hysteresis of 3 °C, it will turn on again at a temperature of 7 °C.
