Frankly I haven’t played around with them, but noticed today that the binding logged an error on startup for the Furnace setpoint:
2018-08-31 19:42:26.823 [WARN ] [.ZWaveThermostatSetpointCommandClass] - Reached max tries to init the setpont Furnace, this will be our last attempt
2018-08-31 20:01:24.071 [WARN ] [.ZWaveThermostatSetpointCommandClass] - Reached max tries to init the setpont Furnace, this will be our last attempt
Ehh, doc says it is the setpoint for the ECO mode, param11. Doc
Well, no channel for it in either PaperUi or Habmin. Psetting is OK.
We should also consider more descriptive names for the 3 temp. sensors on the device:
For the COOLING part,
One place in the manual, under Parameter 1 - Value 2 - Description has the following text: “Cool mode (not implemented)”
Still it looks like this part is working.
If you update the Cooling_setpoint (parameter 13) , - Display is updated correctly.
This also work as an item/channel.
If termostat temperature is above your setpoint it turns the relay on, and act opposite of the Heatmode.
Cooling mode yes. - Can not be used instead of ECO mode as this tries to reach the temperature the “other way”. - If floor/room temperature is lower than the setpoint for cooling mode it wont turn on the relayport. If floor/Room temperature is HIGHER than the setpoint for cooling it tries to turn ON the realyport to reach a lower temperature.
So it works the opposite way than the ECO/HEATING.
This P setting is confusing me. I have the HeatIt v1.8, but cannot find how to change the P setting (when using the P sensor).
It seems to me that this is only added to the later v2.6, but as this is quite basic functionality I find it hard to believe.
Right now the only way I can manage to change it through OpenHAB is through the configuration parameters in HABmin. But it seems that this is not updated if I manually change it on the thermostat itself.
So my question to this forum - is it true that P setting can’t be changed in v1.8? And if so, is it possible to tweak it to get it done?
I snooped in the config-file of the v2.6, I observed the following under channels - is it possible to manually add this in my current config-file for my version?
1.8 seems to have a 2 byte word set for parameter 12, where the other versions this seems to be 1 byte. I’m not sure what it should be - we could see from a logfile, but it’s quite possible this is an error in the database.
Maybe @OMR knows - he seems to be the resident expert on this device .
I couldn’t really tell because all my z-trm2s are v2.6, but what I do know is that:
even for v2.6 chris had to add the P-setting as a channel ‘manually’ (not quite sure how he does that)
for the one device were I use the P-setting, it is working fine. Also reflects changes done on the device.
as for pre 2.6 support: if you read the 2.6 doc carefully (seems to have been pulled from the ThermoFloor WEB site, possible pending their SW Z-Wave certification) it states: P setting is not supported over Z-Wave.
This could have been the case before, but luckily not the case for v2.6
If indeed my TF016 with v1.8 can’t change the P setting over Z-wave, I guess an option is to upgrade the software, if possible. (As I understand it, I have to get a specific cable and I guess I have to have an electrician also to open the thermostat cover…).
Quite frustrating with a lack of such basic operation on a thermostat.
Do you think that a manual insertion of a new channel in the XML as stated above would be possible? I am new to this, so I am worried that I might damage the unit…
As I said, try the support portal or try a thread that is not z-trm2 related.
AFAIK z-trm2 started out on FW v2.6, it does not support that special update cable as it is OTA update only.
I have checked on the PCB, the contacts are not there.
The previous versions have been around for many years, so try to connect with others using those.
I haven’t checked if the new HeatIt-termostat behaves differently than the old one, but the 1st gen one behaved more as one would expect when in ECO mode. So that’s all I’ve been using up until now and therefore also what I want to be able to set in my heating schedule.
IC, I have 2. gen only and never used ECO mode so far, but I agree. Having a channel for Parameter 11 would be nice.
So what you are saying is that such a channel is in place in the binding/database for 1. gen, but not for 2. gen?
If so, we should ask @chris to add it for 2. gen as well. (It’s the database entry I created Chris). Here: Heatit ZTRM 2
