Water heater controller issue

Hi all! I’m a newbie at this forum and in this sphere.
I have a question about the water heater controller. Should I buy it if I have to be away from my house for a long time (vacation, for example)? There will be nobody in the house and I’m worried about its safety. It will be great if it has a function “remote control” or something like this. I have a Noritz NRC66DVNG tankless water heater. Is this compatible with your controllers? And with which ones?
Thanks in advance!
