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%.
Outputs:
Power:
Base & casing: Off-white; self extinguishing
*Triac outputs can only switch AC loads. Use relays when
switching dc loads.
Note 1. Humidity sensor: Solid state humidity sensor.
Suitable for normal, clean air. Not to be used in
corrosive or harmful environment.
