Cooling/Heating allowed not functional

[4ndinger]

Hi there,

I use some of your informations for my Smart Home (Started reverse engineering together with dimu311) and I can not confirm the way how cooling or heating allowed is performing. I set cooling allowed only but the thermostats are opening when the Smartrix Base is not in cooling mode (so It looks like they can heat). Do you have some real thermostats available or based on which information did you mentioned the cooling and heating allowed bits?

Another point is that during my investigation the T-146 sends 3F0C03 all the time. I don’t know what the byte 0x03 represents.

Hi,

I took that from the thread at EEVBlog. I use thermostats for heating and cooling and I have tested when I switch my smatrix from heating to cooling those values change. However I have never tested how to change that value automatically (my smatrix has a physical switch for that).

Hi, on the smatrix base I have the same physical switch as an IO with an 0 potential input. But this will only switch between cooling and heating logic for opening the valves. I thought „cooling or heating allowed“ is for configuring the room if cooling or heating is possible. With you protocol you act like a thermostat (like T-145 or T-146), or?

Hi, I have T-146. That's the thing. There may be some way to configure the thermostats so they are allowed (or not) to change heat or cool... In my setup all my thermostats are allowed to both heating and cooling.

I'm sure that can be changed as well as the setpoint temperature but did not tried as I don't need it.

Let me know if you make any progress

Okay so you think the type of the simulated thermostat is relevant? During my investigation with an T-146 I did not find a major difference to an T-145 at the teach in process. Maybe I need a T-146 again and have a look at this point.
