Glossary
SETPOINT
The temperature at which a room thermostat has been set. This is done either automatically by the EMS
or manually by a guest.
Global Settings
Parameters established by a hotel to guide the automatic functions of the EMS.
Setback
A global setting for the number of degrees that the thermostat will be allowed to drift either up or down
from the SETPOINT temperature while the room is Unoccupied and Rented.
Deep Setback
A global setting for the number of degrees that the thermostat will be allowed to drift either up or down
from the SETPOINT temperature while the room is Unoccupied and Unrented.
Variance
A global setting for the number of degrees that the EMS will allow an occupied or unoccupied room
temperature to change (up or down) from the SETPOINT temperature before the HVAC system is turned
on.
Fluctuation
The number of degrees a room temperature is allowed to change before the EMS activates the HVAC.
Conditioning
The term used to describe the mode of the EMS when a guest is checked-in. At that time the EMS
system immediately goes into “conditioning” mode and changes the room thermostat setting to the
“occupied” SETPOINT temperature. The purpose is to ensure that the temperature is suitable for the
guest by the time the room is occupied.
