[Solved] Heating Control (L series) Comfort <> Efficiency #631
-
|
Hi Folks Is it possible to switch the heating control between comfort and efficiency via Heishamom? I want to switch to Comfort when the outside temperature is low (< 2°C) and the humidity is high, otherwise I will lose heat in the house (due to excessive defrosting). thanks in advance |

In comfort mode, the pump starts at a high frequency so that the target temperature is reached as quickly as possible. The problem in efficiency mode is that the target temperature is not reached within the 35min (minimum defrost cycle) before the next defrosting process starts and the temperature in the house slowly decreases. This phenomenon is always the case when the outside temperature is below 2°C and the relative humidity is above 90%. |

At least using CZ-TAW module (service mode), switching is possible - manually of course. |

I know, but that's not what I wanted. It should be done automatically in HomeAssistant.
I would have to know what I'm doing for that :D |

To set something , you have to set a proper byte , other bytes should be 0x00... In this particular case in #278 , it sets byte29 to 0x10 , with sets Pump flowrate to deltaT... |

My problem is, I don't even know how to identify byte 30, let alone bits 5 and 6 |

Hi,
after spending a whole day trying to get Homeassistant to sending binary via Mqtt, the solution is actually to create a script via the GUI.
In Settings--Automations&Scenes--Scripts--Create Script--Add Action--Other Actions-- Mqtt--Publish enter the following to topic and payload, tick Payload and Evaluate Payload and untick all other options. This is for Comfort mode; for Efficiency, simply replace the x04 in the middle of the payload by x08 (04 is 00000100 in binary, i.e. bit 6 is 1; 08 is 00001000)
Topic (assuming heishamon is your main topic)
heishamon/SendRawValue
Payload Comfort:
