AUTOCAL PROCEDURE
1. Measure the room humidity near the Viconics
humidistat with an accurate hygrometer.
2. Turn the humidistat set point dial to match the reading
of the hygrometer.
3. Push and hold the autocal button for few seconds or
until the internal red light turns on. Look through the
slots on the left side of the humidistat.
SENSOR FAILURE PROTECTION
The sensor is the most sensitive part of the humidistat and
also the most exposed. In the case of a sensor failure in
humidification mode, the H200 will automatically assume a
failsafe output of 0%.
