MENU/SUB-MENU DESCRIPTIONS - Continued
5. Occ Heat Setpoint – determines the heat setpoint that is set when occupancy is
initially sensed after being unoccupied for a period greater than 4 hours. The default
value is 68 degrees. (See **** Note for example)
****Occ Cool/Heat Setpoint example using cool mode (heat would follow the same rules) –
A room has been unoccupied for an extended period of time (greater than 4 hours). The user
enters the room and occupancy is detected – the thermostat will set to the Occ Cool Setpoint
of 73 degrees. The user changes the setpoint to 65 degrees for more cooling. The user then
leaves the room for 20 minutes. At the 10 minute interval, the thermostat will determine the
room is unoccupied and set the unoccupied setback of 70 degrees (65 degrees user setting
plus 5 degrees Unoccupied Setback). When the user returns after 20 minutes and occupancy
is sensed, the cool setpoint will go to 65 degrees (what the user had set when first entering
the room). If the user exits the room and remains gone for more than 4 hours, the thermostat
will change to the unoccupied setback of 70 degrees (65 degrees user setting plus 5 degrees
Unoccupied Setback) after 10 minutes. When the user returns to the room and motion is
sensed, the cool setpoint will change to 73 degrees, and not the 65 degrees that the user had
set when entering the room initially.****
6. Occ Sensor – used to enable/disable the built-in occupancy sensor. The default
value is Enabled. NOTE: This feature does not have any impact/effect on
the use of Lumina RF sensors enrolled into the thermostat.
7. Occ Timeout – determines the amount of time after the last sensed occupancy
before the thermostat engages the unoccupied setbacks. The default value is 10
minutes and can be set from 5 to 30 minutes, in increments of 5 minutes.
8. External Input – a hardwired input can be wired across terminals 1 and 8, supplying
24VAC to terminal 1 to activate an input. The input can be programmed to be a Card
Reader, Occupancy Sensor, or Door Contact. The default value is None."
9. Display Mode – choose between icon or text displays. By default, this item is
set to Text.
10. Balcony Activation – determines the mode of the thermostat when the balcony
door is opened – Setback or Off. The default setting is Setback.
11. Occ Load Command – determines the load command based on occupancy.
The options are On (default) and None.
12. Unocc Load Command – determines the load command issued when the
thermostat determines the room is unoccupied – On, Off, None. The default
setting is Off.
Backlight – this menu item allows you to set the brightness and functionality of the
thermostat backlight. The configurable items are:
1. Level – adjust the brightness of the backlight and in increments of 10%, from
0 – 100%. The default value is 70%.
