3. Adjustment of Control to the Control Sig-
nal
3.1 Brief Description of Controls
Control of the HygroMatik steam humidifer is performed by
sophisticated microprocessors. These microprocessors use self-
adaptive algorithms to intelligently select the steam humidifier’s
most economical mode of operation for the available water qual-
ity. Optimized start-up procedures ensure rapid steam produc-
tion and quick responses to all control processes. The
HygroMatik control regulates the entire blow-down cycle and the
function of the water inlet solenoid valve. With the electrode
steam humidifier, it provides self-monitoring control of the con-
ductivity of the cylinder water. Naturally, HygroMatik micropro-
cessor controls handle all standard control signals.
Three controls will be described in these instructions:
•Basic
•Comfort
• Comfort Plus
Note: The factory setting for the controls is to an „External con-
trol signal, 0-10 VDC“ if no other setting is described in the deliv-
ery note of the humidifier.
3.2 Explanation of Settings
The following descriptions of settings for the possible, accept-
able control signals are presented in parallel for the HygroMatik
controls Basic, Comfort and Comfort Plus.
If the the Basic control is used, parameters may only be modified
by changing jumper settings. On the other hand, software
parameter setting is possible with the Comfort or Comfort / Plus.
If a Basic is upgraded to a Comfort / Plus, the jumper settings
are ignored - the Comfort / Plus operates only as specified by
the set software parameters.
For more information about modifying parameters, also see Sec-
tion „Parameter Setting menu“, or see Section „Parameter Set-
ting with jumper“.
