It is possible to switch multiple systems on one thermostat, if desired. This can be done by the heating wires of both systems to come together in the wall and to connect to the thermostat using clamps in a wall box and then there can be a connecting cable to the thermostat and both systems can be switched to a thermostat. The maximum connection capacity of the thermostat is 16 Amps. For a higher connection capacity to one thermostat, a relay circuit must be installed.
