Introduction
Friedrich EMRT1 Energy Management Thermostats 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.
Energy saving presets eliminate the guesswork and make it easy to adjust the
energy saving settings. (Patent Pending)
Fully congurable energy saving settings allow customizing the thermostat
energy saving settings to t any situation.
Comprehensive conguration options ensure full compatibility with virtually
any existing or emerging hospitality HVAC system with up to 2 heat and 1 cool
stages.
Built-in wireless mesh-networking enables optional remote management.
For installation of a networking thermostat with remote management, refer to the
“Network Installation” manual.
5
Before You Begin
➤ Determine the appropriate installation location for the thermostat. The
thermostat should face the bed area of the room.
➤ Set the PTAC/Vert-I-Pak unit to “External Thermostat” (Class 2) mode.
Consult the PTAC/Vert-I-Pak unit documentation to determine how to set
the PTAC/Vert-I-Pak unit to “External Thermostat” mode.

Before You Begin
Programming a Thermostat with a Network Programmer
In case of Network Installation with Remote Management, the thermostat must
be programmed with a Network Programmer specic to the property before the
installation.
Thermostat must not be powered during the pairing procedure..
➤ Plug one programmer connector into the thermostat;
➤ 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 thermostat and repeat the steps above.
➤ Unplug the programmer from the thermostat;

Thermostat Installation
➤ Set the PTAC unit to “External Thermostat” (Class 2) mode.
Mounting the thermostat to the wall
➤ Unplug the PTAC/Vert-I-Pak unit;
➤ Remove the thermostat cover;
➤ Connect the thermostat wires to the supplied Wiring Connector - refer to
the Wiring Table to determine proper connections;
➤ Plug in the wiring connector into to the thermostat;
➤ Use the supplied wall anchors and mounting screws to secure the
thermostat to the wall;
➤ Follow the “Thermostat Conguration” instructions;
➤ Replace the thermostat cover and screw in the locking screw;
