09.09. Temperature Set Back
Normally, the air conditioning system is turned Off at unoccupied times or at night. The building temperature can
get quite hot (e.g. 30
o
C) or quite cold (e.g. 12
o
C). When you turn on the air conditioning system, it takes a long
time to achieve a comfortable temperature (e.g. 23
o
C). The temperature set back feature will maintain the building
temperature at pre-determined and reasonable temperature closer to your chosen set temperature (e.g. 23
o
C), thus
giving you a big head start in achieving your comfortable temperature.
NOTE
The air conditioning system must be turned Off before performing these procedures.
