I would like to partition the floor into 4 zones
-
Good evening
I'm new to the forum, sorry and my classic English
I have a question for technical experts
I have a printer with Duet wifi + duex controller
Measurement of the printing surface 68 x 68 cm
I would like to partition the floor into 4 zones
How can I control 4 independent zones
The heating panels are 24 vdc pcb without thermistor
Thanks for your advice -
Normally to control a heater with a Duet you would need an associated thermistor sensor as well to complete the control loop.
If the heating panels are intrinsically safe to use without a thermistor, you could use relays to simply power them on and use the Duet to control the relay.
You could configure the heater pins as i/o control pins and use the heater outputs to switch the DC-DC relays on and off.

Does that make sense?
