Setting the Room Temperature
The LRC operates the temperature control equipment available to it to keep the temperature
measured by the Room Temperature Sensor at the set point. Some versions of the Room
Temperature Sensor include an adjustment so the occupants of the room may select the
desired temperature. Other versions do not have that adjustment.
If the thermostat does not include a set point adjustment, then ROOM SETPOINT (Point 13)
must be set through the building automation system (BAS), either using CIS, the field panel
or Insight. Do not set the value of ROOM TEMP (Point 4). This is the temperature reading
from the room temperature sensor; overriding this value will disable room temperature
control.
Siemens Building Technologies, Inc. has two types of Room Temperature Sensors with set
point adjustments. Some of the Series 1000 thermostats have a sliding switch. If you
command the set point from the BAS, it will override the point, and lock out commands from
the thermostat. The series 2000 thermostats have buttons to adjust the temperature up and
down. The LRC processes these commands as though they are BAS commands; therefore
they are not blocked by a BAS command to Point 13.
