# Switching between heating and cooling

### What happens exactly at the base station and thermostat when there’s a switch from heating to cooling?

The base station has a CO input. If this is activated, the base station inverts the signals from the thermostats and transmits them to the valve actuators. An LED indicates that cooling mode is active.
