What is Heating setback?
Cardio can lower the temperature when receiving such commands from a scene (ex: Exit) or a schedule and turn it back to normal after receiving other direct or programmed instructions. In comfort mode, temperature in each zone is that set individually at each zone thermostat. When Cardio is ordered to lower the temperature when turned into economy mode, Cardios own thermostat (display) will take over all other individual zone thermostats and will impose the same temperature in all zone which is the temperature level that has been programmed in “desired tempearture” in the upper right corner of the screen. Later, when receiving another instruction to turn the temperature back to comfort, temperature in each zone will increase until it reaches the temperature individually set on these thermostats.
