Term
[Index] Explanation
Power level
63
If the
HKDB [78]
is equipped with 3 heaters, the power is provided in 2 levels from a certain performance
class onwards. As long as a certain threshold value has not been reached, the heating performance
required in level 1 is exclusively provided proportionally via the
Solid state relay [46] .
After reaching the
threshold value, the heater(s) is/are energised for "base performance" in level 1 via the contactor in 1 step
operation. The power requirement which exceeds the "base performance" is then covered proportionally by
the solid state relay in level 2.
Relay assignment
65
If the basic relay or additional relays which may be present are not used for signalling but for direct load
switching, the maximum contact load 250 VAC/8 A must be taken into account
Power retention
66
After the set temperature has been reached, power is reduced to between 1 and 50% of the nominal output
which was provided previously.The "0" setting means that the function is switched off. The original power is
resumed when the temperature falls below the target temperature.
Control curves
68
In the "Load optimised" factory setting, the power control of an
ELDB [77]
is set so that a current of 113%
of the nominal current is permitted during a cold start to avoid overloading the power supply. In the "Energy
optimised" setting, the current is increased to 128% of the nominal current during a cold start for
achievement of a preferably short heat-up period. In the "Process optimised" setting, control is particularly
fine.
Output signal
69
Signal 0... 10 V on terminals 12 and 13 (GND), which is proportional to the input signal. Can be used to
control downstream units.
Fan control
71
The control may switch 2
supply fans
and 2
exhaust fans
with the respective 2nd fan adding an additonal
performance level (in case of two-stage fans the 2nd performance level is already integrated).
When in "Auto" mode, the following mechanism controls the exhaust fans:
• Switch on exhaust fan 1 when the temperature set value is exceeded (Tactual > Tset)
• Switch off exhaust fan 1 when the actual temperature has fallen below (Tactual - Exhaust fan 1_
∆
Temp.)
• Switch on exhaust fan 2 in addition to exhaust fan 1 (or 2nd performance level) when the actual steam bath
temperature has reached (Tset + Exhaust fan 2_
∆
Temp.)
• Switch off exhaust fan 2 jointly with exhaust fan 1 when the exhaust fan 1 switch-off criterion was reached
Example: Tset = 45°C, Exhaust fan 1_
∆
Temp = 5K, Exhaust fan 2_
∆
Temp = 2K
Exhaust fan 1 switches on, when the steam bath temperature exceeds 45 °C
Exhaust fan 1 switches off, when the steam bath temperature falls below 40 °C
Exhaust fan 2 is additionally switched on when the steam bath temperature exceeds 47 °C
Exhaust fan 2 switches off when the steam bath temperature falls below 40 °C
When in "Auto" mode, the following mechanism controls the supply fans:
• Switch on supply fans 1 and 2 as long as the actual steambath temperature has not yet reached the set
value (Tactual<Tset)
• Switch off supply fan 1 when the actual temperature has reached the (Tset + Supply fan1_
∆
Temp.) value
• Switch off supply fan 2 when the actual temperature has reached the (Tset + Supply fan2_
∆
Temp.) value
Example: Tset = 45°C, Supply fan 1_
∆
Temp. = 4K, Supply fan 2_
∆
Temp. = 2K
Supply fans 1 and 2 switch on, as long as the steambath temperature is below 45 °C
Supply fan 2 switches off when the steambath temperature has reached 47 °C
Supply fan 1 switches off when the steambath temperature has reached 49 °C
Dropout delay
74
By assigning the "8" value to one of the relay contacts, a control signal for the delayed closing of a steam
valve is made available for pressure reduction. The dropout delay is set with the "Humidification_off_delay"
paramter. Factory default is 60 s.
Main contactor
75
The installed main contactors are labelled K1...K4. The operating cycles of the main contactor(s) are
monitored and compared with the value specified by the manufacturer for the expected service life. When
the stored value is reached, the message "Service_main_contactor" is generated. After the main contactor
has been replaced, the status message must be deleted, for example using the
Main_contactor_K1_Reset = "1" parameter.
ELDB
77
Electrode steam humidifier.
HKDB
78
Heater steam humidifier.
SPA
80
Collective term for use of the unit as a steam bath and organic sauna
Stopping time
82
If the interlock (safety) system is opened, the respective supply and steam bath fans continue to run for the
stopping time specified to assist in the drying of the steam bath.
Intensity
83
The intensity of the essence injection can be changed incrementally from 0... 10, where "0" switches off the
respective essence.
Pause time
84
The time between two essence doses. Essence is only dosed when steam is also produced.
