T is for an outside thermostat so won't be used - tape it off.
White should go to the AUX connector.
B blue/cyan to the C connector.

Welcome to the forums.

R ------> red --------> R
T ------> tan ---------> tape off
O ------> orange ----> O/B
G ------> green ------> G
Y ------> yellow ------> Y
X2 ----> white -------> AUX/W2
B ------> blue --------> C

Program your new thermostat for heat pump with backup heat.
