Remote Thermostat
All Friedrich Vert-I-Pak units are congured to be controlled by using a dual stage heat/cool remote wall mounted thermo-
stat. The thermostat may be auto or manual changeover as long as the control conguration matches that of the Vert-I-Pak
unit.
To connect the wall mounted thermostat:
1. Pull the disconnect switch.
2. Unscrew and remove the control box panel.
3. Select which side to run your thermostat wire.
4. Run the wires through the side hole in the box to reach the connection terminal wiring.
5. Make the connections, appropriately matching the wires as shown in the wiring diagram.
6. Reattach the control box cover.
Note: It is the installer’s responsibility to ensure that all control wiring connections are made in accordance with the instal-
lation instructions. Improper connection of the thermostat control wiring and/or tampering with the unit’s internal wiring
can void the equipment warranty and may result in property damage, personal injury, or death. Questions concerning prop-
er connections to the unit should be directed to the factory.
Note: Any non-Friedrich thermostat or low voltage device being powered by the Vert-I-Pak will need to be reviewed and
approved for use.
Note: For additional information, please review the latest Friedrich Vert-I-Pak Service Manual.
