Odd behaviour for MCZ stove #116

Closed Webbeh closed 3 years ago

Webbeh commented 3 years ago

Hi.

I've made a box to control MCZ pellet stoves. It uses a raspberry pi and the new RFXCOM versions (batch 21xx), with ProXL 1 firmwares (version 1044).

Everything seems to work fine, except... When the fan speed is at "1", this node says that the command isn't recognized.

Whether fanSpeed is an array of the right size, an array of the wrong size, or a simple number, I get that error whenever the model is "1 fan".

Node-red 1.2.5 node-red-contrib-rfxcom 2.11.3

A fan speed of 1 is accepted only if the flame power is set to 2 or less, not if it is 3 or more. Presumably this is to prevent overheating?

This behaviour is embedded within the RFXCOM itself, not the node. I hope this helps!

Oh wow, can't believe I missed that.

I did that check but somehow removed it, didn't think to check...

Well, thanks...

This behaviour doesn't seem to be documented anywhere I could find, although I did find a warning about using fan speed 0 with flame power other than 1.

I believe I saw it either in the SDK or in the quick start manual. Anyway thanks.

Couldn't find the limitations anymore but there's some details for anyone who find this issue later.

That is similar to what I have in the SDK documents, but not exactly the same. The behaviour with fan speed = 1 isn't documented though. Thanks for posting - this will be a useful reference
