A frost protection thermostat can be connected to the SKC6.. actuator. The added
signals from the QAF21.. and QAF61.. require the use of SKC62UA actuators. Notes
on special programming of the electronics are described under «Enhanced electronics»
on page 5.
«Connection diagrams» for operation with frost protection thermostat or frost protection
monitor refer to page 16.
