Thermostat in regulator mode can't be added to dashboard

I have one thermostat, CTM lyng thermostat, mTouch one OP.
This is set to function as a regulator.
In the climate section, the thermostat is found.

When I try to add the same thermostat in dashboard, the thermostat couldn’t be found.
If I change the mode from regulator to thermostat, it can be found in the climate section of dashboard.
Is this a bug or an expected behavior?
Anyone else with an thermostat set to regulator mode?
