Connection of passive controllers
Passive controllers (potentiometric humidity sensors) supply a resistance value
(passive control signal) and should be connected according to the adjoining
diagram. Please observe the following connection data:
Connection voltage:
Resistance values:
Min. conductor cross-section:
When connecting a potentiometric humidity sensor the rotary switch "SW2"
must be set to position "4".
Connection of a humidity sensor
Connection of a humidity sensor (option "TR116S/TR200" or "TR116R/TR200")
