Every HygroMatik humidifer is equipped with terminals 1 and 2.
These terminals function as the connection for the safety inter-
lock. The safety interlock contacts, such as the max.-hygrostat,
vane relay, duct pressure sensor, air interlock etc., are laid in a
series between erminals 1 and 2. The enable switch or safety
interlock must be closed in order for the humidifier to operate.
Humidifier Terminals
Double-cylinder units are provided with a standard enable
switch, i.e. both cylinders are enabled simultaneously. Upon
request, each cylinder can be equipped with its own enabler
switch.
Risk of overhumidification due to humidity sensor failure!
Installation of a max.-hygrostat in the safety interlock is a must
to protect against overhumidification as a consequence of
humidity sensor failure.
Use of proper contacts is mandatory!
Contacts across terminals 1 and 2 must be potentialfree and
rated for 230 VAC switching.
