GM1111 40 Revision Date 4/3/2014
The RCU-O contains the following additional onboard sensors:
 Group Volts: Measures instantaneous RMS voltage for a group of outlets.
 Group Amps: Measures instantaneous RMS current for a group of outlets.
 Outlet Amps: Measures instantaneous RMS current for each outlet.
 Outlet Real Power: Average of instantaneous voltage and current over last 1.5 seconds for
each outlet.
 Outlet Kilowatt-Hours: Cumulative sum of Real Power for each outlet.
Remote Sensors
Available Sensors:
 RT: Temperature
 GTHD: Temperature / Humidity / Dew Point
 GT3HD: Temperature / Humidity / Dew Point with ability to add two RT sensors
 RTAFHD3: Temperature / Air Flow / Humidity / Dew Point
 CCAT: Converts analog I/O Sensors to Remote Digital Sensors
 IOE: Expands the number of I/O and sensor ports and adds relays
 DM: Remote digital RMS current Meter
 RS2: Remote power monitoring and switching
*RTAF, RTAFH & RTHD sensors have been discontinued and replaced by the RTAFHD3 sensor.
Some Geist R-Series devices may require a firmware update to allow for proper compatibility with
the new RTAFHD3 sensors.
If your Geist R-Series device is using firmware version 2.xx you will want to make sure you are
using firmware version 2.94 or newer.
If your Geist R-Series device is using firmware version 3.xx you will want to make sure you are
using firmware version 3.5.0 or newer.
Please contact Geist Support at 800-432-3219 if you need assistance locating your current version
or upgrading to the new firmware version
RTAFHD3 Compatibility
The (G)RTAFHD3 sensor cannot be utilized in combination with the discontinued (G)RTAF
and (G)RTAFH sensors or (G)RTHD sensors built prior to 2010. If you desire to add
(G)RTAFHD3 sensors to an existing installation currently utilizing incompatible sensors,
please contact Customer Service for installation options.
Connecting Remote Sensors
Plug-and-play remote sensors may be attached to the unit at any time via the RJ-12
connectors on the face of the unit. In some cases splitters may be required to add
additional sensors. Each sensor has a unique serial number and is automatically discovered
and added to the web page. Up to sixteen sensors may be connected (15 on RCU-O).
The display order of the sensors on the web page is determined by the serial number of
each sensor. Friendly names for each sensor can be customized on the Display page.
