Controlling a device based on 2 inputs

Temperatures don't fluctuate that much so I set the injects to one minute interval, more that sufficient for the heater.

I was directed to this post by @krambriw from one that I just wrote last night here:

Heating panel from scratch

I've been reading the forum but can't find anyone that has built a complete heating panel from scratch in NR. I'm going to move all my home heating from my Fibaro HC2 to Node RED and TBH I already have a plan on how to do it that will work fine. I recently built a panel to control my instant hot water which in a sense is a simple heating panel, and it works fine. I'm just interested to see if anyone else has done it before to see if I can pick up any nice ideas. I get this is a very broad qu…

I'm sure you guys have considered this already, but with the instant hot water panel that I have recently built, I have my main engine (which runs in a NR function node) also trigger every one minute, like @mintgroen suggested , this is perfectly adequate for heating IMHO, however I also added 3x more triggers to run the engine more frequently:

1. if a temp value changes
2. if a pump status changes ie. someone overrode a pump from another interface
3. if a user changes any config from the VueJS/uibuilder interface

With the above 3x triggers it means that the panel runs "instantly" from the users perspective ie.. if you change a temp setpoint or turn a zone on/off, you see the action executed within less than a second of making the change....

I have not read this entire thread, so apologies if you have covered the above off, but I thought I'd share this as it seemed like a good idea to me to implement it at the time.
