If you have Climate Control with Display type for air con..there is no need for coded work to be done and would imagine the same goes for the 3 knob type control panel..if it is 3 knob type controls just make sure it is an Air con one..the climate control type can only be Air con
Are you sure it is panel..only ask as I had issues with climate control and tried another display control panel with no luch turned out to be a blower fan fault which replaced and now working correctly.
