Connection With Humidistat With Resistive Output; Connection With Humidistat Which Suspends Humidification When Ventilation Is Suspended - Elsteam KT Series Manual

6.3.3 Connection with humidistat with resistive output

TERMINALS
1 Connection with humidistat resistive output (+)
2 Connection with humidistat resistive output cursor
3 Connection with humidistat resistive output (-)
4-5 Short-circuiting
The electrical resistance between terminal 2 (cursor) and terminal 1 (+) increases as the relative humidity of the room
increases,whiletheresistancebetweenterminal3(cursor)andterminal3(-)decreases.
