Setting the Day and Time
Upon initial power-up (or after a power loss of
greater than 6 hours), the T600MEP-2 shows a
SetClock
alarm. As the thermostat scrolls through
the Status Display Menu, the
SetClock
message
causes the backlight to light up until the clock is set.
When adjusting the time with the UP/DOWN arrow
keys, holding the keys down changes the time in
30-minute increments.
To set the clock while in the Main User Menu:
1. Answer NO to all prompts until the clock set
prompt appears in the display. Press YES to
enter the clock set menu.
2. Press YES to set the time or NO to advance to
the
day set
menu.
3. Use the UP/DOWN arrow keys to adjust the
time. When the correct time is displayed, press
YES to store the time.
4. Press YES to enter the
day set
menu or NO to
enter the clock format menu.
5. Use the UP/DOWN arrow keys to adjust the day.
When the correct day is displayed, press YES to
store the day.
6. Press YES to choose the time format or NO to
access the Main User Menu exit prompt.
7. Use the UP/DOWN arrow keys to select the
desired time format. Press YES to enter format.
8. Press YES to return to the Status Display Menu
or NO to return to the
time set
menu.
When the thermostat scrolls through the day and time,
the new day and time should be displayed (and no
alarm/backlight should be present). If the day or time is
incorrect, repeat the
Setting the Day and Time
procedure.
Setting Schedule Hold
This menu is used to set a permanent hold on the
internal scheduling or resume the schedule. The
permanent hold is typically used for unscheduled events
that extend for long periods of time.
Note:
Displayed only if Digital Input DI1 or DI2 is
configured for remote NSB.
Following are the three selections for this menu:
•
Permanent Occupied Hold (occ hold)
This selection puts the thermostat into a permanent
occupied mode using the occupied setpoints.
Occupied hold
appears in the Status Display Menu
when this selection is active.
•
Permanent Unoccupied Hold
This selection puts the T600MEP-2 into a permanent
unoccupied mode using the unoccupied setpoints.
Unoccup hold
appears in the Status Display Menu
when this selection is active.
•
Resume
This selection cancels the permanent hold and
enables the regular program schedule.
To enable the permanent hold feature while in the Main
User Menu:
1. Answer NO to all prompts until the schedule hold
prompt appears in the display. Press YES to enter
the schedule hold type menu.
