Hi
I have a couple of Airwick Freshmatic Max Auto room spraying units , the have 3 settings on them I=9 minutes , II=18 Min and III=32 min .
I would like to change the time settings to spray every 60 Mins or there about's etc .
Is there anything I can make up to do that , or is there any module that I can fit , will post some pics of the Board later today , I don't have a Schematic for the board , will try draw something .
Just saying it now without the pics etc in case someone on here already knows about them ! .

Cheers

Spike

 

Looks like a Blob chip, with a few external components, you need to trace the switch wires to see what's happening , my guess is its done in the programme..

Scroll to 16:55 for pcb image..

 

Hi
Thanks for your reply , have seen that vid , good one but it is not addressing the the time sequence for the bursts , I need some mod to have the sequence time gap much larger than it has ie , the longest is 32 mins , far to frequent ,would like it to spray hourly ! .

cheers

OK , that is not the same board as in my Airwick Freshmatic MAX , pics as follows .

 

No it's a different one , but it looks like it's a microcontroller probably a pic, and the timing is done in the software.

 

this wont work I dont see any clocking parts on the board, cant be changed.

But you can use something like a 10F200 + digital MOSFET to turn it on every hour, maybe it starts puffing by itself or needs some pushbutton worked by a line, like if youd be pressing it.

 

Hi
Thanks all for your feedback , I am thinking of removing the board all together and fitting some other timer to the motor ,but would need some sort of overload device to switch of when the active arm reaches its stop , or it would either burn the motor out or flatten the batteries ! .
I think that would be correct !!!

Chip : RB 1401C , SAG 3C3

 

Could this be the Chip !

Hi,I need this type of circuit board.
