| Pairing to CCU

Pairing the MyStat with the Central Control Unit (CCU) allows it to communicate with the CCU and terminal-level equipment in the ClimaVision system.

Steps For Pairing

In the CCU interface, in the Floor Layout tab, add a floor and a zone. Then click Pair Module to pair a module as a MyStat terminal profile.

On the Select Device Type screen, select the MyStat.
On the Select Module Type screen, select a profile.
On the MyStat, press and hold both the up and down arrow buttons for 3 seconds. Then press to navigate to the Installer Options screen.
Use the up and down arrow buttons to navigate to Pair with CCU. Then press to select.
In the CCU interface, select the Bluetooth address that matches the one shown on the MyStat's Advertising screen.
In the CCU interface, enter the 6-digit PIN shown on the MyStat's Advertising screen and click Proceed.
On the Pairing Steps screen, click Pair.

Alternate Pairing Method (Not Using Bluetooth)

If there are no devices found after attempting to pair, or the desired device does not appear as an available device, click Connect to pair the MyStat manually.

Note the pairing address displayed in step 3 of the Manual Pairing Steps screen shown below. You will enter this address into the MyStat.

On the MyStat, press and hold both the up and down arrow buttons for 3 seconds. Then press to navigate to the Installer Options screen.
Use the up and down arrow buttons to navigate to Pair with CCU. Then press to select.
Wait 15 seconds. When the Manual Pair option appears on the Advertising screen, press the down arrow button to select it.
On the LwMesh Address screen, enter the pairing address displayed on the Manual Pairing Steps screen in the CCU interface. Use the down arrow button to adjust the value and press to select the next digit.
Press the button on the MyStat to confirm the pairing address.
In the CCU interface Manual Pairing Steps screen, click Pair.

Once paired, choose and configure a profile.
