Description of parameters

Tel. +358 (0)201 2121 • Fax +358 (0)201 212 205

Set here the temperature maximum limit for the coolant. If the temperature exceeds the set
limits a temperature fault is instigated.

1599

Autochange

interval

(2.10.11)

After the expiry of the time defined with this parameter, the autochange function takes place.
The available time range for the autochange varies from 1 to 168 hours.

Test mode; Autochange after 30 seconds

1 to 168 Time range for autochange in hours
169

Single motor used; no autochange

The time count is activated only if the Start/Stop request is active.

The time count is reset after the autochange has taken place.
