FCC AND IC REGULATIONS

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation of the device. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

● Reorient or relocate the receiving antenna

● Increase the separation between the equipment and receiver.

● Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

● Consult the dealer or an experienced radio/TV technician for help.

BLUETOOTH® PROGRAMMING AND OPERATION

A. Pairing A Mobile Device With A CT Thermostat

Before you begin, ensure you are standing within 3’ (1 m) of the CT thermostat you wish to pair your mobile device with. Do not touch the CT thermostat for 15 seconds to ensure the backlight is

off. Conrm the Bluetooth® icon is blinking slowly (ashes at 2 second intervals).



If the Bluetooth® icon is illuminated, this device is already connected to an app. Disconnect the other mobile device in order to connect to this CT thermostat.

If the Bluetooth® icon is not visible the Bluetooth® radio may have gone to sleep to conserve power (after 5 days of system inactivity). Press any button to wake the Bluetooth® system and ensure the icon is blinking slowly.

1. Open the Dometic Climate Control App on your mobile device and go to the pair management screen. If no CT thermostats are paired with the mobile device this will be indicated with a pop-up. Press OK the clear the pop-up and display the Pair Management screen.

a. If you already have CT thermostats paired with the mobile device the app will attempt to

connect to the last used thermostat or the default thermostat (see "C. Setting/Unsetting The Default Device" on page 15). Press Cancel while connecting is in progress to show the Pair Management screen

b. If a paired thermostat is connected, the main screen displays. Select the Settings menu

and then press Disconnect to show the Pair Management screen.

2. Press Add New Connection. See FIG. 6.
