Recommendation on How to Use Scenes

-----------------------------

Choosing how to use scenes depends on the needs and lifestyle of the customer
using the building.

Multi-Tenant Apartments

Scenes should be disabled (None) in multi-tenant buildings where the each occupant
has differing heating requirements.

Residential Homes
Some residential customers may not require scenes, in which case, scenes can be
disabled (None). Home owners that wish to save on energy costs should consider
using the Away scene to save energy while away from the property (example:
vacation or holidays).

The use of the Guest scene is useful in residential applications where there are a
number of spare bedrooms that are occupied on an infrequent basis. Each spare
bedroom would be setup to operate on the Guest scene. The remaining thermostats
can be setup to operate on the None, Away or All scene configuration. Normally,
the spare bedrooms would operate at the moon temperature settings. When guests
arrive, scene 5 can be activated through the use a User Switch or Gateway. The
spare bedroom then operates at the temperature settings or operates on a
programmable schedule if a schedule has been setup. When guests depart, the
scene can be changed back to scene 1 and the spare bedrooms resume operation
at the temperature settings.

Commercial Buildings
Commercial buildings are typically in use on a predictable schedule and normally
the building can operate in scene 1. In order to accommodate staff working overtime
or cleaning staff, a 3 or 8 hour temporary override is available when installed in
conjunction with a User Switch or Gateway. In these cases, the thermostats should
be setup to use the All scene configuration. At the touch of a button, the whole
building changes from operating on a programmable schedule (typically at the
temperature setting when not occupied) to operating at the temperature settings
for 3 hours (scene 6) or 8 hours (scene 8). After the timer counts down and expires,
the scene changes back the previous scene.

Secondary Temperature Display

Section H

This thermostat can display the outdoor or floor temperature in the upper right hand
corner of the display. Touch the upper right hand corner to toggle the item currently
displayed. Display of the floor or outdoor temperature requires a connection to an
outdoor or floor temperature sensor, or the thermostat is connected to a tekmarNet

system that includes an outdoor sensor. The reading of the outdoor sensor connected
directly to the thermostat takes precedence over any outdoor sensor reading available
on the tekmarNet

system.
