Intelligent Delayed Start default is in OFF mode.

To switch ON Intelligent Delayed Start enter the Installer Options

Menu (Refer to Installer Options 06).

Note the Intelligent Delayed start option is not suitable for

Hydronic underfloor application.

Ensure Installer option 06 is set to OFF before final commissioning

for Hydronic underfloor application.

Special Note:

If the Intelligent delayed start feature is enabled, (Off

changed to On in Installer option 06), please inform the end

user of this feature.

The following special note has been added to the user

instruction to explain the adjustment requirement:

When the delay period is operating indicated by the flame symbol

flashing (Fig12), pressing any button returns the Digistat +2/3RF

(Fig 5)

to auto mode allowing normal button operation until the next

time/ temperature event, when it will resume the delay start

mode or follows the Holiday, Manual, Override or Off modes as

selected.

Changes to the installer options and pre-set programmes must be

made with the flame symbol not flashing.

(Option 10)
