Not sure on that one - I'm backpacking at the moment and don't have a screen with me.
Think I've found a solution on different forum: http://answers.microsoft.com/en-us/windows/forum/windows_8-performance/setting-display-off-time-puts-computer-to-sleep-at/3849b335-67c6-4606-a443-9dacf4040ace?page=2

For those looking to disable Connected Standby on Clovertrail (and similar) Devices:
A simple change of a registry key and a system restart exposes all the legacy functionality:
HKLM\System\CurrentControlSet\Control\Power\CsEnabled (1->0)
I can set a monitor sleep timeout and the monitor actually turns off without sleeping the whole device!
I can run "nircmd monitor off" and it actually turns off the monitor upon request without tripping a standby mode.
I get the good ol' power plan switcher when I click the battery icon in taskbar.
I get tons of previously hidden options inside each power plan's advanced settings.
* I had previously tried disabling Desktop Activity Moderator (dam.sys) and this kept my desktop processes from freezing upon monitor-off in Connected Standby mode, but they were still cut off from system devices like sound and network. Since my efforts were
to enable downloading to continue with the screen off, this was still unacceptable.
* Power Usage and Battery Life: With Connected Standby disabled, and monitor off, my idle battery drain was ~0.9w (Acer Iconia W510 tablet, WiFi connected, Bluetooth enabled but not connected.) This translates to roughly 30hrs of battery life
in this state, before complete depletion. I have my unit set to shut down when battery becomes critical, so we still have a mechanism in place there.
