4.2 Overview of Steam Bath Operation and Installa-
tion
The necessary steam for the operation of the steam bath is supplied by
the HygroMatik Steam Generator. The recorded temperature in the
steam bath is the only control variable for controlling steam production.
At the default setting, the steam bath achieves a temperature of about
45°C at 100% relative humidity. A steam bath air supply fan may be
used to deliver fresh air, and an exhaust fan to remove warm air from
the steam bath, in order to ensure continuous steam supply and a sta-
ble temperature control.
Heat-Up Phase:
Steam is supplied to the still cold steam bath, increasing the relative
humidity to 100% at an initially constant temperature. Subsequent
steam delivery then increases the temperature; the relative humidity
remains at 100%.
Operating Phase:
When the desired temperature (plus hysteresis) is reached, steam pro-
duction is interrupted. If the steam bath temperature falls below the
desired value, steam is again delivered into the cabin.
Light control, fan control and essence injection control are optional
accessories.
HygroMatik steam bath systems are available either in 24V or 230V
versions.
Risk of electrical shock hazard!
Inside the steam cabin, safe low voltage (24V) for the fan and light is a
must.

4.2.2 Steam Bath - Temperature Control
With any steam bath, a temperature sensor must be installed in the
cabin. The temperature sensor measures the temperature in the
steam bath and is connected to the steam generator.
The DS-Comfort or DS-Comfort Plus controls the HygroMatik steam
generator according to the temperature reading. The relative humid-
ity is not measured since it is always 100% following the heat-up
phase. In addition, depending on your order preference, you can con-
nect an essence injector, light and fan to the steam generator.
The sample diagram below shows how the DS-Control functions:
Parameters G1 to G4 + G13 (may only be modified in operating mode)
are programmed as follows:
Hysteresis Temperature Controller (G1) = 1K
Hysteresis Steam Bath Exhaust Fan (G3) = 1K
Hysteresis Steam Bath Supply Fan (G13) = 1K
Steam Bath Temperature Set Value (G2) = 45°C
If the temperature in the steam bath falls below 45°C, an adjustment is
made by increasing steam production.
If the temperature in the steam bath rises above 46°C, steam produc-
tion is shut off with 1-step operation or adjusted downwards with con-
tinuous operation.
The release point for the steam generator is determined as follows:
Steam Bath °C Set Value (G2)+Hysteresis °C-Controller (G1) =
45°C+1K = 46°C.
If the temperature in the steam bath rises above the programmed tem-
perature set value of 45°C, the DS-Control activates the steam bath
exhaust fan. The control switches off the exhaust fan below 44°C. The
release point for the steam bath exhaust fan is determined as follows:
Steam Bath °C Set Value (G2) -
Hysteresis °C Steam Bath Exhaust Fan (G3) =
45°C - 1K = 44°C
The Parameter “Steam Bath Exhaust Fan” (D1) must be programmed
to automatic.
Steam is only produced as long as the temperature in the steam bath
remains below the “set temperature value.” If the temperature in the
steam bath remains above the “set temperature value” for a long
period of time, resulting in this case in no visible steam production,
this could be due to:
• excessively high heat supply from an additional source, e.g.
from heated benches.
• a well-insulated steam bath
•
Air flow in the steam bath is facilitated by a steam bath exhaust fan,
causing the temperature in the steam bath to fall more quickly.
Renewed steam production compensates for the drop in temperature.
In this way, the fan ensures constant, stable steam production - with

5. Operating Mode - Advanced Communica-
tion with the Control (Comfort-/Comfort
Plus-DS)
5.1 Introduction to the Comfort- DS / Comfort Plus-
DS Control
Control of your HygroMatik steam humidifier is performed by sophisti-
cated microprocessors. These microprocessors intelligently and self-
adaptively select the most economical mode of operation for the steam
humidifier appropriate to the existing water quality. Optimized start-up
procedures provide rapid steam production and quick responses to all
control operations. The HygroMatik control regulates the complete
blow-down procedure and the operation of the water inlet solenoid
valve. For electrode steam humidifiers, it self monitors to control the
conductivity of the cylinder water.
The HygroMatik microprocessor control Type DS is a particularly user-
friendly control, delivering the user all important information.
The Comfort- DS /Comfort Plus- DS Control features:
• a lighted alphanumeric LC-Display
• an (optional) RS232 or RS485 interface as the basis for the
Modbus RTU protocol
• optimal adaptivity of the steam generator due to wide parameter
adjustability
• 5 LEDs on the display panel give an instant overview of the most
important operations
• Stand-by blow-down to prevent standing cylinder water. After a
long period with no steam production, the cylinder is completely
drained
• 4 connections for control of the steam bath supply and exhaust
fans, essence delivery system and light
• Remote control (optional)
• selection of steam bath operations with or without status indica-
tor
• variable temperature control depending on operational mode
The performance options and available settings for your HygroMatik
Control Type DS-Comfort and DS-Comfort Plus are explained below in
detail.
Both the HygroMatik Comfort Control and the Comfort Plus consist of a
main PCB and a display unit with back-lighted display, as well as an
LED with icons and keys for direct communication with the control.
