On finishing maintenance work, the service interval
is to be reset
(the service icon is blanked if it was
illuminated before).

service inter-
val
Main contactor switching cycles are monitored and
compared to the life expectancy figure supplied by
the part‘s manufacturer. On a match, reading value
r01 is set to „270“ (and the service icon LED
flashes). After changing the main contactor, param-
eter 3-2 must be set to „1“ for a reset of the status
message.
3-3
Steam ser-
vice interval
Unit control monitors the actual steam amount pro-
duced and compares it with the service steam
amount that was determined by the parameter 3-3
setting. When the two data match, the service icon
is lit. Steam humidifier operation is not disrupted.
Service rate highly depends on water quality (con-
ductivity, hardness) and on the amount of steam
produced since the last service. By varying parame-
ter 3-3, the service interval may be adjusted to
water quality.
