RGBW Module in Irrigation panel

It is possible to add Fibaro RGBW module to irrigation panel for controlling 4  12V valves ?

Yes that is a fine solution, we use lots of RGBW controllers for electric heating and other stuff.

 

Always use a

(inverse polarity !!!) on the valve coil to protect the RGBW outputs (eliminate voltage spikes across an inductive load)

 

Or maybe better connect a

to the RGBW outputs and connect the valves (high power on 12 volt dc) or other stuff (230 volt ac) to the solid-state relays

This circuit are we using for many electric heaters controlled by my Lua code on Fibaro HC2's, and we use solid-state relays because they are silent, no standard relais clicking noise.

Thank you Xirilius for useful info . If you use RGBW for  underfloor heating  you can not add this to Heating panel ? You use LUA for programing heating ?
