If a retail outlet does not open for several days, the SCS Controller can return the cooler to full Standby Mode to reduce its power use. This can occur in several stages. For example, if no activity is detected during the initial 'Inactivity Wait Time – Transition 3' period, the SCS Controller returns the cooler to 'Full Standby Mode', and is ready to start the 'Pulldown' again at the start of the next day as per normal. Should any activity be detected while the cooler is in 'Full Standby mode', the SCS Controller will immediately commence a 'Pulldown' to bring the cooler back to the preferred Set Point temperature.

Detail |
|
tS1 |
Transition 1 Set Point |
The temperature at which the Compressor will turn off when the system is running in Transition 1 Mode. Transition 1 Mode is the second step in the Standby process to conserve power during prolonged periods of inactivity. |
|
tS2 |
Transition 2 Set Point |
The temperature at which the Compressor will turn off when the system is running in Transition 2 Mode. |
|
tS3 |
Transition 3 Set Point |
The temperature at which the Compressor will turn off when the system is running in Transition 3 Mode. |
|
ytn |
Inactivity Wait Time – Normal Mode |
The time the SCS will wait in Normal Mode without any activity being seen before it moves to Transition 1 Mode. An activity is any interaction with the cooler cabinet, which is detected by a sensor, such as a door opening. |
|
yth |
Inactivity Wait Time - Standby Hold |
The time the system will remain in standby with no activity before transitioning back to Transition 3 Mode. |
|
yt3 |
Inactivity Wait Time – Transition 3 |
The maximum time permitted in Transition 3 Mode without any detected activity, before switching to full Standby Mode. |
|
Sbt |
Maximum Standby Time |
The maximum time permissible for the system to remain in standby without any detected activity. |
