Compatible timer with Ideal Logic Max C24 Combi?

[Snorwin]

Looking for advise on compatible "plug and play" RF timer thermostat to go with Ideal Logic Max C24 Combi. Not looking for anything fancy as for a rental and obviously price dependent but struggling to find compatible options that don't require wiring in. Not bothered about mobile phone compatible etc, just RF.

OR other option - wiring diagram/video I can follow to wire a non plug and play one in!

Thanks in advance, ideas would be appreciated.
