Wiring advice for swapping Honeywell BDR91 for Heatmiser RF

Hi, I have a Warmflow combi boiler, with a Honeywell BDR91 that I'm replacing with a heatmiser rf. The Honeywell is wired L&N which is obvious and Black to A, Grey to B. On the heatmiser am I correct to put Black to Com1 & Grey to No1. Using heating only not hot water. Thanks

Re: Replace Honeywell wireless thermostat with Heatmiser rf

Hi, I have similar setup as this the only difference is Black is A & Grey is B on Honeywell. So Black to Com1 and Grey to No1 on Heatmiser RF?
