Heating adjustment inside the actuator
The heating element has been set at the factory, so it starts heating from an internal device temperature of 0 °C (32°F). For environ-
ments with higher temperatures and high humidity, the heating threshold must be increased, in order to prevent moisture conden-
sation inside the housing. The heating threshold can be set via the heating adjustment.
The following table shows the positions of the heating adjustment and in which corresponding temperature ranges the heating ele-
ment will heat.
