Hi I have had to send back my spark due to a problem with one zone not operating, I’m now trying to do a reset on my whisper, I have pressed the power button quickly 6 times, on numerous occasions and cannot get it to reset, any help would be much appreciated. New Spark arrived and working well, l just can’t seem to reset the Whisper no matter how many times I try the on/off 3 times. Are there any other action I could do or do I return it for a replacement?
