Q; Control 2 heaters using just one PIDKiln? #40

Closed ilgrank closed 4 months ago

ilgrank commented 1 year ago

Hi This is question (not an issue): is it possible to use PIDKiln to control an oven with two (one upper, one lower) indipendent heaters? Thanks!

Saur0o0n commented 1 year ago

Yes, you can - it's still enabled at the same time, but it can have different/independant power source.

#define EMR_RELAY_PIN 21
#define SSR1_RELAY_PIN 19
//#define SSR2_RELAY_PIN 22   // if you want to use additional SSR for second heater, uncoment this

Thanks for the reply and that's true even for a second temperature sensor? I mean, can the two heaters behave independently (say, set 800°C for the upper part of the chamber and 700°C for the lower part?) In my current setup I'm using two independent PIDs, but I would want to control the Kiln remotely

Hi, nope - as I said, they act as a single heater but with two separated power sources. And there is only single temperature sensor for kiln interior - other sensor is for outside temperature.
