Term [Index] Explanation
Second temperature sensor 45 For enhancement of the temperature measurement reliability or the consideration of the influences
introduced by on-site particularities, the control may be operated with a 2nd temperature sensor.
Prerequisite is the unit's configuration level with an expansion board or a relay board in addition to the
mainboard. The 2nd sensor is connected to the relevant connector plug on the respective p.c.b., just as the
1st sensor is. Activation of the 2nd sensor is made by setting the "Sensor 2_connection" parameter
within the "SPA" submenu to setting variant "Cylinder extension" or "Relay 1 extension" (De-activation is
accomplished by selecting the "Off"-setting for the a.m. parameter).
Measuring value processing can be made in two ways:
1.
Averaging the readings of both sensors with a defined weighting
2. Comparison of the two readings and generation of a fault message in case of deviation
Selection processing method is made by setting the "Temperature_measurement" parameter within the
"SPA" submenu. Setting options are "Average" and "Deviation". Averaging takes both measurements in
concern for forming a new value that is relevant for further processing. "Sensor 1_weighting" with a 0 to
100% range defines the impact of each of the sensors on the total result.
Scaling is as such:
"0%" = only the sensor 2 measurement value is taken into account
"50%"= the measurement values of both of the sensors determine the average value with an identical
weighting
"100%"= only sensor 1 measurement value is taken into account
When "Deviation" is selected, only the sensor 1 measurement value is processed, as long as a significant
deviation is not detected. However, when a significant
has occurred, the fault message "Deviation" is
generated. The criterion for this message is the degree of deviation that may be set as the
"Sensors_deviation"
parameter (s. SPA submenu) between 1.0K and 10.0K.
Solid state relay (SSR) 46 Electronical power switch mounted on a thermically monitored heat sink (only

HKDB [78]
).
Humidification 47 The unit produces steam, if a temperature sensor has issued a

Demand [5]
and the

Interlock (safety)
system [11]
is closed.
PWM 48 P ulse w idth m odulation with variable frequency and variable duty cycle for the control of the heater current
via the

Solid state relay [46]
. Because the heater current determines the steam output, it is possible to
control the steam output in this way (only for

HKDB [78]
).
Δ
Temp._ECO 52 To save energy, the ?
set value
of the steam bath can be lowered by the value stored in "
?
Temp._ECO".
For this purpose, a

pushbutton [106]
has to be wired to the
?Digital input
and the function of the digital
input has to be programmed to "ECO".
Steam_down_time_to_fault 53 If the level of the cylinder water has not changed within the time defined in this parameter, this indicates that
a malfunction is present. The steam production is then suspended and the "Steam_down_time" fault
message is output (only

HKDB [78
].
Filling_cycled 54 The fill operation does not take place continuously , but with breaks, in order to prevent the overflowing of the
filling cup (HyFlow). Filling and pause intervals can be adjusted separately.
Blow-down correction 55 If the water has high electrical conductivity or if there is a very high level of maintenance, it may be useful to
increase the blow-down frequency. At low electrical conductivity, however, a reduction in the frequency of
the blow-down may be useful. Depending on the water quality, the blow-down rate can be adjusted in 10
steps ("0" is the default). More frequent blow-down: Values up to max. +5, less frequent blow-down values
down to -5, whereby "-5" means that blow-down is completely switched off.
Pumps_without_main_contactor 56 In rare cases, leakage currents may flow through the water to the earth during the blow-down process. To
prevent a sensitive FI switch from being triggered, the main contactor can be switched off during the
pumping process (only

ELDB [77
].
HyFlush (option) 57 When open, an additional solenoid valve produces a rotating turbulence for an improved discharge of scale
deposits during blow-down. The solenoid valve is controlled by the software with a fixed ratio of active and
pause times.
Blow-down 58 Pumping off the water in the cylinder for the following reasons: Elimination of scale deposits, replacement of
water to prevent germ formation and reduction of conductivity (only

ELDB [77]
), which increases due to
evaporation and leads to increased power consumption. A distinction is made between

Full blow-down
[22
] and 
Partial blow-down [21]
.
HyCool (option) 59 Waste water cooling system for the protection of temperature-sensitive plastic waste water pipes. A
solenoid valve is used to mix fresh water with the waste water so that the water temperature does not
exceed 60 °C.
Steam jet activation 60 A steam jet can be triggered manually if a

button [106]
intended for this purpose is wired between the

Auxiliary voltage [105]
at Pin 3 of ST08 (mainboard) or ST05 (relay board) and the

Digital input [97],
and the 
Digital_input_function [98]
has been programmed to "Steam_boost". When triggered, the steam
bath set temperature is increased in the short term to a value which results from the set tempe
?
steam_boost. The duration of the target temperature increase is determined by the "Steam_jet_duration"
parameter. The value of the "Steam_jet_blocking" parameter determines the time between the last steam jet
and when the next steam jet can take place.
