VAPOR-LOGIC
®
VERSION 6 INSTALLATION AND OPERATION MANUAL
SENSOR OFFSETS
All external transmitters shipped with Vapor-logic can be field calibrated
from the Settings menu . For example, if the system is equipped with an RH
transmitter, there is an RH offset setting .
The factory default for all transmitter offset settings is zero . The sensors that
have this adjustment capability are the humidity, duct high limit, temperature
compensation, and dew point transmitters .
SKIM TIMER
The Vapor-logic controller has a skim timer . This timer is activated at the end
of each probe check . The timer keeps the fill valve open (for a user-determined
amount of time) to skim minerals off the water surface . The skim time is
adjusted through water management in the Settings menu .
END-OF-SEASON DRAIN
If there is no call for humidity for a user-defined time period, the humidifier
performs an end-of-season (EOS) drain where the drain valve remains open
for ten hours to allow the tank to drain and then closes . If the humidifier
receives a call for humidity after the ten-hour end-of-season drain-down period
has begun, the controller stops the end-of-season draining, the tank refills,
and the humidifier resumes normal operation . The user-defined inactivity time
period (idle time) is defined in the end-of-season drain section of the water
management settings menu .
SERVICE INTERVAL
The Vapor-logic controller tracks the amount of water converted to steam by the
humidifier and the number of hours the humidifier runs . When the amount of
steam or hours of run time exceeds the user-defined service interval (pounds,
kilograms, or hours, adjusted in the Settings menu), “Service unit” appears in
the Messages Log on the Web interface or in the Alert Log on the touchscreen
display . On the touchscreen display Status and Quick Diagnosis screens the
user will also see the words Service Due: Yes .
The humidifier continues to operate after the alert appears . The alert notifies
the user that the service interval was reached and the humidifier should be
cleaned . The alert remains active until the user manually clears it, indicating
that the cleaning was completed .
