VAPOR-LOGIC
®
VERSION 6 INSTALLATION AND OPERATION MANUAL
The Universal Water system allows the Vapor-logic controller to identify the
water type using a three-probe assembly. All water types and conductivities
work with the universal water system. The user does not need to select a new
water type or change hardware to change water types. Additional valves
and Vapor-logic algorithms measure and control the water level for optimum
efficiency and low water safety conditions. Vapor-logic automatically provides
a steady output while maintaining the water level between the bottom and
middle probes.
Water must remain in contact with the probe surface for three seconds for
Vapor-logic to determine that the water is at the probe’s level. Conversely,
water must stay out of contact with the probe surface for three seconds
for Vapor-logic to determine that the water is below the probe’s level. This
three-second delay ensures that turbulence does not cause an incorrect level
reading. If the water level falls below the low-water cutoff probe for a time
period determined by Vapor-logic, heating outputs are disabled; this provides
low-water protection for the heating outputs. If Vapor-logic detects water on
the top probe Vapor-logic will assume there is foam and a foam drain will start
immediately.
The humidifier will periodically perform probe checks to insure that the probes
are being read accurately and to determine the quality of the incoming water.
The humidifier status on the home screen will show “Probe Check”. After a
probe check the humidifier will adjust the Smart Drain usage interval used for
the automatic drain sequence. If the signal from the probe assembly begins
to deteriorate, the “Clean probes” or “Check Water Probe” message appears
in the Alert log. Once the probe system reaches its maximum usable life, the
humidifier shuts down and the user gets a “Faulty Water Probe” active alert.

Chloride corrosion
Damage caused by chloride corrosion
is not covered by your DriSteem

Chloride corrosion can result from a
variety of causes, including, but not
limited to
• Improper water deionization
processes
• Improper water softening processes
