Thermoactuators

Activating the thermoactuators
The thermoactuators are supplied with a "first open" function, which
means that they are slightly open for frost protection until the electrical
controller is installed. During commissioning, the "first open"function
is disabled by removing the red mounting split on the thermoactuator.
Please check that the thermoactuators can fully close following
disabling of the "first open" function.
See the installation guide included with the thermoactuator.
