Replace room thermostat with Shelly Wall Display

[Hummingbird77]

I currently have a digital room thermostat on the wall that controls a servomotor in the living room. I would like to replace this with a Shelly Wall Display. 
So far, I haven't found any real information about whether it is possible to control a servomotor directly with electricity using the Shelly Wall Display. Specifically, this means that the Wall Display would then have to switch the power through to the servomotor. I think this is possible, but I wanted to ask to be sure.
At the moment, a current-carrying cable goes to the room thermostat, which supplies the cable to the actuator with current when the temperature falls below a certain level and thus opens it.
