Error write on type 0x1D #268

Closed mellbo closed 4 years ago

mellbo commented 4 years ago

My boiler: Bosch Condens 2500W

I have one error in the function ems_setWarmTapWaterActivated(bool activated) I try to send manualy to boiler 8B 08 1D 00 5A 00 64 FF with no result. Is any trick to put this boiler into Test mode ?...

Hmm. Not sure. Does anything come back as a response to 1D?

nope.

and one more things at ems_setWarmWaterActivated(bool activated) for 0x33 type, at address 01 "WW ENABLED/DISABLED" is not 0xFF for ON. For this boiler 0x08 means ON and 0x00 is OFF and address is not 0x01. Corect address is 0x00.

so, for the Bosch Condens 2500W I think this line EMS_TxTelegram.dataValue = (activated ? 0xFF : 0x00); must be replaced with EMS_TxTelegram.dataValue = (activated ? 0x08 : 0x00);

Any other person that have Bosch Condens 2500W at here ?

@mellbo thanks for reporting the setWarmWater issue. You are correct that with Heatronics the values are x08 for ON. I checked also with https://github.com/norberts1/hometop_HT3/blob/65be31e9265599f198d7d6c7aa9b8e4f5939ded4/HT3/sw/lib/ht_discode.py#L2012

made the change in 1.9.5b6
