Two choices;
4-wire connection (best): connect pins T1, T2, T3 and T4 to one of the 4-way terminal blocks on the PT100 daughter board in the same order (it doesn't matter which end you start from). Remove the jumpers from the two pairs of jumper pins on that channel of the daughter board.
2-wire connection: connect T2 and T3 to the middle 2 pins of the 4-way terminal block on the PT100 daughter board. Fit jumpers on both pairs of jumper pins on that daughter board channel.
See the wiki for how to configure PT100 sensors in firmware.
