Can't get heater pads working

Hi, I have three Harvst heater pads, hooked up to aux control 3 on my Watermate, mains version, through a Harst supplied splitter cable. I can't get them to heat.

I've tried these two options:
- Turn on when Temperature [ID 8904] under "Wired sensors" in the dropdown is below 20, limit to 90 seconds, wait 1 minutes before running again. Nothing happens, even when the temperature has been well below 20 degrees celcius for hours.
- Or use timers: On at 8 am for 3 minutes.

No heat can be felt with any of these options. I'm assuming Temperature [ID 8904] is the short, probelike temperature that hooks up to the Watermate's dedicated port for this.

Am I not understanding something? I can't find any directions on how to hook it up, so I thought it would be as straightforward as my attempts.

3 minutes may not be enough to give a noticeable warmth, especially in the summer. The heaters are designed for propagation in Winter/Spring and don't generate a ton of heat ( intentionally )

I would suggest having the heaters on for a long period on a timer ( over 10 minutes )
Or else turning on when temperature goes below X, set limit to 0; then the heaters will remain on while the temperature is low. Note that if you are using temperature sensing, you'd need to consider how you place the temperature sensor relative to the heaters.

It may be best to turn the heaters on when general air temp is under 10C, they don't get hot enough to cook plants. Then when the day warms up above 10C, they will turn off.

Thank you, I'll give that a whirl. I wasn't sure how warm the heaters could get, and didn't want to overdo it. Might be a good idea to say something about that in the manual or on the product description in your webshop

I tried setting heaters to turn on when temp is below 12 degrees celcius, limit 0. Last night was several degrees below that, according to the watermate app, so the heaters should have been continually on for several hours. When I checked this morning, while temperature still was around 8 degrees, there was no discernible heat. I get that you don't want to cook plants, but if there is no noticable difference between pads on or off, how effective can they be?

And how can I tell if they actually work? Maybe my splitter cable is faulty? Will the pads turning on be logged in stats, like watering is? Or is there somewhere else I can see if they're active?

Hi Thomas
When the box turns on, it runs a hardware test. The results are logged; so if you do a power off/on, then go to Settings > View logs on the device control panel ( via its wifi ) you should see the results of the Aux 1/2/3 tests. Can you paste them in here?
