Can this actuator be used as a replacement for a Sunvic SD 2701 Answers1

Yes it can.

Hi a Engineer has fitted a Actevator Valve. Danfoss, HSA3. the problem is,he does Not know the Wiring,which wire goes where?
The problem was,the Heating could not be switched OFF? only comes on when the Hot Water comes Heating can NOT be Switched OFF? Answers1

Blue - Neutral
Orange - Output to pump and boiler
Grey - H/W off
White - Heating on.

I have removed the existing HSA3 actuator during DIY, but foolishly I’ve lost the 2 fastening screws, so I can’t refit it. Do you supply these screws as spares or can you let me know the size and type so that I can source them please. Thank you. Answers1

They are M5 x 35mm

Hello, Could you confirm this is a brand new actuator and not reconditioned? Thanks Terry Answers1

Hi Yes, all our products are brand new items.

Has my actuator failed, when in hw mode it is in midway position hw and heating. when i turn hw off it stays in that postion and actuator body feels hot all the time. Heating rads works ok. Answers1

It sounds like it has stuck. It could be either the actuator or valve body. You will need to take it off to check.

Going to use the HSA3 to replace the Sunvic SD2701. Am I correct to assume that the HSA3 Brown/white wire replaces the White wire in the SD2701. Blue, Grey, orange remain the same? Thanks for any help. Answers1

Yes that's correct.

P/N 5933 is a label. The actuator type should be on the opposite side of the actuator.

could you please inform me when and why you would operate this actuator valve in the manual mode.. thank you . Answers1

Manual mode is for filling the system, or as an override should the actuator fail.

the unit that I have is considerably ''old'' - my question is has the model changed in anyway or should it be compatible to the unit I have marked only as HSA3? Please advise - thank you Answers1

No, it has not changed. It will be a direct swap.

Hello, is this a mid position actuator? Answers1

Yes it is.
