Bosch Combi zone control wire to Uponor Smatrix Pulse controller board

I have a Bosch Singular 5200 and a Uponor Smatrix Pulse zone controller.

I became confused because relays are behind a NO 110V panel door. Is this a warning for people with 110V outputs trying to connect them? Or is it a warning I will fry a dry contact with 110v if I try to connect it? I do not want to guess. please help.

I only want to connect my Bosch combi Zone Control wires to the Smatrix controller which are dry contacts.

How do I wire them together? Which pair/terminal do I use to connect the Bosch combi to the Uponor Smatrix.

From my Bosch Singular 5200 Manual:

Here are pictures of the wires on the combi and the terminals on the Uponor Smatrix controller.

From the Uponor Smatrix Plus Manual:
Under the cover of the Uponor Smatrix Pulse Controller (Zone actuator / controller):

Here is the manual although this is the European version which is 230V I have the 110V. https://brandportal.uponor.com/m/802baa60a5b3ed2/original/IOM-Smatrix-Wave-PULSE-EN-1095344-v2-202006.pdf

Can anyone help?

    Uponor support confirmed that the brown zone control wires on the Bosch combi should be connected to the boiler relay on the smatrix pulse controller. 
    I didn’t want to to risk frying my controller. The no 110V confused me.
