DN 15/ 25: closes against pressure
DN 40…150: closes on pressure
The return spring causes the actuator to move to the «0 %» stroke position and
closes the valve.
• Voltage on Y1 piston extends valve opens
• Voltage on Y2 piston retracts valve closes
• No voltage on Y1 and Y2 piston / valve stem remain in the respective position
• Signal Y increasing: piston extends valve opens
• Signal Y decreasing: piston retracts valve closes
• Signal Y constant: piston / valve stem remain in the respective position
• Override control Z see description of override control input, page 5
A frost protection thermostat or temperature detector can be connected to the
MKD662.. control device.
The added signals from the QAF21.. and QAF61.. cannot be connected.
«Connection diagrams» for operation with frost protection thermostat or frost pro-
tection monitor refer to page 15.
