Thermostat that can lock temperature

Hello, I have a tenant that never open the heater in the winter. This is causing lots of damage in his apartment. I am looking a thermostat that can lock the minimum temperature. The apartment is heating with a baseboard Heater. Thank you

There are lots of thermostats in the market that let you program minimum and maximum temperatures.
If you’re trying to use something like the CT/GoControl thermostats then you’re better off putting a rule in CoRE/WebCoRE to adjust the min/max temp if they fall below certain threshold. This obviously assumes that the thermostat is connected to your hub and has a reliable/stable connection.

I am looking thermostat that can lock minimum temperature to avoid tenant change the configuration.
