A southerner and ethnic Malay Muslim in predominantly Buddhist Thailand, Wan Noor has served previously as house speaker and has close ties with Pheu Thai's leadership.
"I will conduct duties fairly ... with transparency in considering draft laws and petitions to improve the lives of all Thais," Wan Noor told the house.
Pita on Tuesday said Move Forward had "retreated" on its position having been assured by Wan Noor that its policies would be supported.
The two deputy speaker positions will go to Move Forward and Pheu Thai.
"What we do not know is whether Pheu Thai will switch sides if the initial vote for Pita fails."
