The groups that are affected by the programmed holiday period are assigned using the 2=Assign groups function.

On selecting the Assign Groups option, the groups currently assigned to the programmed holiday periods are indicated by a Y below the group; an N is displayed below the unassigned groups. All groups default to Y. Pressing the group number toggles the group status. When the required groups have been assigned to the holidays, press the ent key to accept the programming and return to the previous menu level.

NOTE: The Galaxy 3-520 has more than 8 groups; these are displayed on the keypad in blocks of eight groups. Press A or B keys to display each of the group blocks.

3=Early Open

If the Early Open option (45.3.2) is enabled, the Lockout OFF time for the following day is brought forward by the number of minutes (0 – 240) programmed by the engineer. This allows the system to be manu- ally unset earlier than normal. There are 2 functions within this option:

The 1=Early Times function displays the time that the system can be manually unset on the following day; this time is the Lockout OFF Time minus the Early Open period and is displayed in the 24 hour format.

If groups have been enabled, the early opening time for each of the groups enabled for early opening in the Early Open option can be viewed by pressing the A or B keys

This function only displays the early time if the Early Open option is enabled; if this option is disabled or if no groups have been enabled, the message NO ENTRIES is displayed.

The 2=Early Open function permits early opening to be disabled or enabled.

If groups have been enabled, then the groups can be individually ena- bled to permit early opening.

4=Timers

This option allows Timer A and Timer B to be switched on and off as required. If a Timer is set to off, the operation of the Timer is sus- pended; this option cannot be used to alter the programmed times. Both timers default to 0 = Off. To switch the timers on, select the required timer and change the setting to 1 =On.
