  • Page 3: Product Description

    The DOL 36CT Climate Computer units have the following auxiliary functions: Automatic display of DOL 78CT’ preset emergency temperature and the Climate Computer unit set point (= required house temperature), when the emergency temperature is changed and when switches are made between normal operation and emergency operation.

  • Page 4: Functions

    Tunnel mode: The DOL 78CT will only go to emergency opening in case of power failure, or defect temperature sen- sors. This means when running in Tunnel mode the temperature dependent emergency opening is deactivated.

    2.2 Special ! Extension of the 24V supply capacity If the total motor current exceeds 4.25A the 24V supply capacity can be increased by supplementing DOL 78CT with a DOL 78M ON/OFF emergency opening unit and a DOL 78CT Extension module mounted in DOL 78M.

  • Page 6: Operation

    If the Climate Computer unit is in batch operation, where the house temperature is automatically lowered slightly every day, the DOL 78CT switch must be adjusted regularly in order to follow the temperature lowering of the climate computer. If the DOL 78CT emergency temperature is not lowered so that it is more than 6 higher than the climate computer set point, the warning “Emergency temperature too high”...
