Introduction
Friedrich VRPXEMRT2 Energy Management Wall Controllers deliver
unprecedented energy savings without compromising occupant comfort.
An Integrated occupancy sensor uses a combination of motion and thermal
sensing technologies for accurate occupancy detection. Reliable occupancy
detection allows for energy savings when rooms are unoccupied.
Energy saving presets eliminate the guesswork and make it easy to adjust the
energy saving settings. (Patent Pending)
The Wall Controller has RS485 connectivity needed for connecting the Wall
Controller to Friedrich’s VRP®and FreshAire®PTAC units with RS485 interface.
Built-in wireless mesh-networking enables optional remote management.
FOR INSTALLATION OF NETWORKING WALL CONTROLLERS WITH REMOTE
MANAGEMENT, REFER TO THE NETWORK INSTALLATION MANUAL.
LOGIN TO THE REMOTE MANAGEMENT WEBSITE TO CONFIRM
THE SERVER IS CONNECTED TO THE INTERNET BEFORE
INSTALLING WALL CONTROLLERS. DO NOT INSTALL WALL CONTROLLERS IF
THE SERVER IS NOT CONNECTEDTO THE INTERNET.STOP THE INSTALLATION
AND CONTACT TECHNICAL SUPPORT. START BY FIRST INSTALLING A WALL
CONTROLLER IN THE ROOM CLOSEST TO THE SERVER.
LOG IN TO REMOTE MANAGEMENT WEBSITE TO CONFIRM THAT THE WALL
CONTROLLER IS ON THE REMOTE MANAGEMENT WEBSITE WITH THE
CORRECT ROOM NUMBER. CONTINUE BY INSTALLING ADDITIONAL WALL
CONTROLLERS IN ADJACENT ROOMS ONLY AFTER CONFIRMING THAT
INSTALLED WALL CONTROLLER(S) HAVE CONNECTED TO THE WIRELESS
NETWORK AND THE REMOTE MANAGEMENT WEBSITE .
IF INSTALLED WALL CONTROLLER(S) ARE NOT CONNECTING TO THE
NETWORK AND DO NOT APPEAR ON THE REMOTE MANAGEMENT WEBSITE
WITH THE CORRECT ROOM NUMBER, STOPTHE INSTALLATIONAND CONTACT
TECHNICAL SUPPORT THE ROOMS FURTHEST AWAY FROM THE SERVER
SHOULD BE INSTALLED LAST.

Before You Begin
Determine the appropriate installation location for the Wall Controller.
The Wall Controller should face the bed area of the room.
WALL CONTROLLER MUST NOT BE INSTALLED NEAR OR ON METAL
STRUCTURES OR SURFACES INCLUDING METAL AIR DUCTING THAT MAY BE IN
THE WALL. METAL STRUCTURES AND SURFACES SIGNIFICANTLY REDUCE THE
RANGE OF THE WIRELESS SIGNAL.

Programming a Wall Controller with a Network Programmer
In case of Network Installation with Remote Management, the Wall Controller
must be programmed with a Network Programmer specic to the property before
the installation.
Wall Controller must not be powered during the pairing procedure.
• Plug one programmer connector into the Wall Controller;
• Push the black button on the programmer. The red light on the programmer
should turn on and remain steadily lit; If the red light on the programmer
is blinking or is not steadily lit, unplug the programmer from the Wall
Controller and repeat the steps above.
• Unplug the programmer from the Wall Controller;

Wall Controller Wiring Installation
There are four sets of connections for the VRPXEMRT2 Wall Controller. The
supplied cable from the VRPXEMRT2 Wall Controller as shown in Figure 1,
has four color coded wires. Each of these wires must be connected to two Cat6
wires (not supplied) as shown in Figure 2. Each connection is made with a lever
type connector. Four connectors will be needed to complete unit wiring. Each
connector is capable of connecting three wires.
