Controller LED Indicators
The controller has eleven Light Emitting Diode (LED) indicators (see FigureLCM-OAVS
Room Pressurization with Two Slow-acting Venturi Air Valves (One Supply, One
Exhaust) and Hot Water Reheat). Table Controller LEDs lists the type, the abbreviation
on the controller, and the indication of each LED.

Temperature Sensors
Temperature sensors used with the LCM-OAVS Room Pressurization with Two Slow-
acting Venturi Air Valves (One Supply, One Exhaust) and Hot Water Reheat include an
electronic room temperature sensor and an optional duct temperature sensor.
Room Temperature Sensor
The controller room temperature sensor connects to the controller by means of a cable
terminated at both ends with a six-conductor RJ-11 plug-in connector.
See the Ordering Notes section for the location of the room temperature
sensor/Human Machine lnterface (HMl) port.
NOTE:
When using a Series 2000 Room Thermostat:
During
unoccupied mode, you cannot change the Room Setpoint using a Siemens
Industry Series 2000 thermostat. Any attempt to change Room Setpoints during
unoccupied mode using a Series 2000 stat will be ignored.
During
occupied mode, the Room Setpoint can be changed using a Series 2000 stat,
but if it is, then the controller initial values should be uploaded to the field panel.
Otherwise the controller will not keep the adjusted Room Setpoint value upon return
from a power failure.
Duct Temperature Sensor
An optional duct temperature sensor provides duct air temperature sensing inputs to
the controller.
For more information about temperature sensors, contact your local Siemens Industry
representative.
