I bought this thermostat to control air circulation, that is using it for cooling purpose. So far I managed to make it work, but I do not fully understand the wiring scheme. I would appreciate help to fully understand the scheme.
In the scheme L is linked to 3 squares where the middle one labelled with "5". The square to the right is connected to the square labelled with "2"? What is the purpose of this connection?
The square to the left of "5" is connected to the square labelled "N" using a dotted line. What is the purpose of this connection?
The model number is RTR-E 6732 https://docs.rs-online.com/8e9b/0900766b800ccc84.pdf
I found another wiring diagram where the unlabelled blocks are lacking (see page 9) https://docs.rs-online.com/ae5d/0900766b81583b25.pdf
