Hi to the Community and to @Vinny...

I am in the fence to change my actual Doser and i am considering get the SA 2.1 but have several questions before i pull the trigger:

1. What is needed in order to use the 4th pump as a ATO Refill? Does it uses a common input?
2. Same question as above for the Temp Sensor?
3. After each Dose does it have an alarm that indicates the use?

Thanks in advance for the help and as you can see i am trying to compare with the one i have know vs move to another brand.
