Wireless thermostat swap wiring advice

I’m planning to remove a Neomitis RT7RF wireless thermostat and replace with a Honeywell T4R, controlling a WB combi boiler.
Both have a simple 4 wire connection, and I know I can just reuse the existing wiring.
My question is which terminals to swap the switch wires from/to?
The Neomitis terminals are labelled “3” and “4”.
Honeywell terminals are labelled “A” and “B”.
Diagrams for both attached.
I think 3 on the neomitis becomes A on the Honeywell, and 4 becomes B, just wanting to check.

Fitted and wired the Honeywell today. All working. Thanks for the help Chris W.
Anyone reading / interested I took the Neomitis off because it only had 3 on/off setting periods during the day, and all had to be at the same temperature. The Honeywell advertises max. 6 periods - effectively has 5 as one period is overnight - but all can be different temperatures.
