Hi,

I have a Voltek 1812 controller and the lux setting does not work. So I bought a new 1812 complete and still no good. It either senses and works both day and night or if I turn down the lux setting nothing works. The TLX override works fine. I have followed the instructions but simply cannot get it to work correctly. Very simply just to come on when it dark. Am I doing something wrong? Any ideas. 

The lux info comes from the pirs. You should only have 1 lux sensor connected. Maybe you have a faulty sensor or a cable issue, do you have another pir you could use the lux from? 

Hi, thanks for getting back to me - there are 3 pir sensors around our building and the issue is the same for all of them. Any ideas please?

Have you disconnected the current sensor for lux level and connected one of the others? Bear in mind you should only have 1 lux sensor connected? 

No - I have 3 pir units around my property. So are you saying I should disconnect two of them and only have 1 connected yo set the lux level and then I then reconnect the others when it works. Sorry I am not sure what you mean. Please could you clarify. 

Yes there should only be one lux sensor connected you should have the 3 S connected but only 1 L. 

Sorry I simply do not understand what you mean by 3 S and 1 L? Are you saying I need to disconnect 2 of the PIR units, set the lux to the only remaining PIR and then when it works correctly I connect the 2 I have disconnected? Seems difficult and didn’t need to do this when I replaced the 1812 unit last time. Is this correct?

Are you in Halesowen? I live in Hagley. Do you have an engineer who could come out to my property?

Im sorry we only supply equipment to installers etc.

 

Could you recommend anyone at all please?

Im afraid I cant, however our customers do frequent the forums here so maybe someone will offer their services.
