Page 5: Introduction
Introduction Friedrich VRPXEMWRT2 Energy Management Wall Controllers for the hospitality industry deliver unprecedented energy savings without compromising guest comfort. Integrated occupancy sensor uses a combination of motion and thermal sensing technologies for accurate occupancy detection. Reliable occupancy detection allows saving energy when rooms are unoccupied. - Page 6 VPXEMWRT2-Thermostat Manual_pkg.indd 6 2017-12-15 3:37 PM...

Page 7: Before You Begin
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. -
Page 8: Pairing The Wall Controller And The Receiver
Wall Controller and Receiver must be paired in order to operate together. Once paired, the Wall Controller cannot be used with another wireless Receiver without repeating the pairing procedure. Friedrich Wall Controllers are pre-linked with the card in the box. -

Page 12: Wall Controller Wiring Installation
There are four sets of connections for the VRPXEMWRT2 Wall Controller. The supplied cable from the VRPXEMWRT2 Receiver as shown in Figure 1, has four color coded wires. Each of these wires must be connected to two Cat6 wires as shown in Figure 2. - Page 13 Wall Controller Wiring Installation General Connection Procedure: Figure 3. 1. Remove 2” of the outer sheath of the CAT6 cable including the shield and strip the wires. 2. Insert the specified wire from the Receiver into a slot of the lever connector as shown in Figure 3 and close lever as shown in Figure 4.
