I am trying to swap a danfoss icon thermostat that connect to my wiring center to another that has zigbee support. I tried t wire it up but at first it seems to power up although when trying to put LOAD as in starting to heat the wiring center doesn't detect anything and is not opening the actuators now I am not sure if I bought the wrong type of thermostat or my wiring is wrong with me bridging the wrong contacts in this place. Pictures below for wiring setup and devices. I would appreciate any help.

The old Icon thermostat had wiring where Brown was L , Blue was N and Yellow/Green cable was Load L

I wired the zigbee one as follows where Brown is L , Blue is N and the 1st contact is the Yellow/Green while bridging the 2-3 Contacts as it seems that's how its done on the Danfoss Icon one with the sticker showing the two N's bridged.

The wires come to the wiring center accordingly with Brown to L , Blue to N and Yellow/Green to LOAD.

Update: I'm dumb I just bridged neutral connections which obviously does nothing. I moved the cable 1 connection to 2 and Bridged contact 4 with 1. Now everything works properly.
