Example 1:
A house is normally in scene Permanent 1. There is a
master bedroom that operates on a schedule and there is
a guest bedroom that is normally set to Unoccupied. When
a guest arrives, the scene changes to Permanent 4. Scene
4 has been pre-programmed to change the guest room to
operate on the schedule.
Master bedroom thermostat:
Scene Permanent 1 is set to Schedule.
Scene Permanent 4 is set to Schedule.
Guest bedroom thermostat:
Scene Permanent 1 is set to Unoccupied.
Scene Permanent 4 is set to Schedule.
Example 2:
A house is normally in scene Permanent 1. There are
bedrooms upstairs and the entertainment area is downstairs.
The occupants are entertaining guests for an evening and
scene Temporary 7 is selected. This causes the upstairs
thermostats to operate at the Unoccupied temperature and
the downstairs to operate and the Occupied temperature
for four hours.
Upstairs thermostats:
Scene Permanent 1 is set to Schedule.
Scene Temporary 7 is set to Unoccupied.
Downstairs thermostats:
Scene Permanent 1 is set to Schedule.
Scene Temporary 7 is set to Occupied.
To set the temperature while the occupants are away, use the
Permanent Away 2 scene. This scene changes all thermostats
on the network to the Away temperature setting. If there is
an Outdoor Reset Module on the tN4 communication bus,
the boiler no longer responds to domestic hot water calls
for heat. Setpoint demands continue to operate as in the
Occupied mode. • • To set the number of days away, go to the Scene menu
and select Away Hold.
When set to Infinite, the Permanent Away 2 scene remains
until a new scene is selected. If you know in advance how
long the building occupant will be away, you can adjust Away
Hold to the number of days. Once the number of days have
elapsed, the thermostat automatically changes from the
Permanent Away 2 scene to previous permanent scene.
Example: The home occupants are traveling for 14 days. They
want the home to be at the Away temperatures for 14 days
and then automatically return to the normal schedule.
•
• Away Hold is set to 14 days.
•
• Scene is changed to Permanent Away 2.
Away Temperatures
An Away temperature setting exists for both heating and
cooling. By default, the Set Heat Away temperature is set
to 62°F (16.5°C) and the Set Cool Away temperature is
set to 85°F (29.5°C).
•
• To set the Away temperature, go to the Adjust menu
and select the Set Heat Away and the Set Cool Away
items. The Access Level must be set to Installer or
Advanced.
Length of Time Away
The Away Hold feature allows you to set the number of
days the Away temperature applies.
