# J1V5 Air-conditioning Setpoints

## **What are the specified heating thermostat settings for conditioned zones in climate zones 2 to 8 according to the requirements?**

The heating thermostat setting is 20°C for all conditioned zones from 6:00 am to 12:00 am (daytime), and 18°C at all other times (night-time).

## **In which climate zones is the cooling thermostat setting 27°C for daytime conditioned zones from 6:00 am to 11:00 pm?**

The cooling thermostat setting of 27°C applies to daytime conditioned zones in climate zones 1, 2, and 3.

## **What is the cooling thermostat setting mandated for all climate zones?**

These settings are specified for the daytime and night-time periods as required by the compliance standards for air-conditioning services in different climate zones. The nighttime cooling thermostat setting is a constant 24°C for all night-time conditioned zones across all climate zones.
