Horstmann HRT4-ZW

[smartronix 0]

Hi guys,

Has anyone a manual how to connect the HRT4-ZW to a fibaro 1x3kW switch and control it with the HC2? I can connect it with the fibaroswitch and i can connect it with the HC2, but not both the same time, anyone has any idea?

Hi Giz,

Sounds similar to some of the issues I had.

For a while all changes worked other than the afternoon to night change and the manual change. I was never sure why this started working

/emoticons/default_icon_confused.gif" alt=":-?" /> so not sure it is fixed.

I always suspected it was a configuration code issue not an execution bug . I felt if the configuration was correct then it would have worked and was almost on the point of looking in the database.

All I did just before it all started working was go through all of the HRT4-ZW hitting configure to default values then open and save the room configuration pane on the heating panel.

The bug could easily still be hidden in there and I was just lucky or one of my HRT4 had not been configured correctly and caused the issue.

I can’t reproduce now:- I have removed and added and messed around but it works without fault for me now.

Must be worth opening the bug again.

robmac,

i've tried to reconfigure all heating panels from the scratch.

Seems to all start working now. Mystic...

Good news... we will never know why.

Added multiple HRT4-ZW to my HC2, everything is fine except it could not be used as a sensor in a linked devices panel.

Syncing with Danfoss Valve with a scene. Works fine.

to Fibaro team - could you please provide more convenient way to sync settings (without scenes)?

Installed 1x ASR-ZW (to control a boiler), made associations (group1) with all HRT4-ZW (all rooms), works just fine.

When I'm changing something on HRT, it is synced with Danfoss valves and also (in case it is required) heating is turned on or off.

ASR receives commands from HRT virtually instantly, Danfoss valves are syncing when awaken (by a schedule).

Will see how climate panel works...

After moving I reinstalled my HC2 and it works well. For the HRT4-ZW I have a request. Is it possible to use the temp sensor of the HRT4-ZW as sensor in HC2? That way I could use it as mail sensor of a room and read it from the app.

I'm also having an issue adding this device. When I add, it appears as a radiator thermostat - configuration never completes and I cannot update the setpoint or read current temp.

The procedure I'm using is

add device in HC2

Set dipswitch 1

L mode (press button on thermostat)

Device adds but configuration window just sits there

Where am I going wrong?

I had the same problem. After including, select the n on the HRT (this when the HC2 is in config mode) the HRT wil now configure.

Great - thank you that worked a treat.

Amazing, I've previously had this working with Homeseer and never used that option before!

Hi Guys

I am looking to buy this thermostat to control my heat pump.

Although I am still not sure if its working right according to what u guys have written here.

After adding it to HC2 will it allow me to set the correct temp on HRT4 through HC2? Or the temperature always has to be set manually on HRT4?

Regards

[robmac 173]

Mine work but use batteries faster than I think they should.

Added multiple HRT4-ZW to my HC2, everything is fine except it could not be used as a sensor in a linked devices panel.

Hmm, I actually was going to buy HRT4-ZW and use its temperature sensor in the following scenario:

- Linked device: electrical relay valve, temp. sensor in HRT4-ZW

- Heating panel > Standard mode: linked devices holds the temperature configured in HC2 heating panel

- Heating panel > Manual mode: activated by a new temperature set up in HRT4-ZW, linked devices holds then the new temperature configured in HRT4-ZW (by LUA). Manual mode is active for n hours defined in a global variable MANUAL_TMT, than activates standard mode again (by LUA).

So if HRT4-ZW's tempearture sensor cannot be read in HC2, I have to have an additional temp.sensor

It can be read in lua with

local sensor_Hall_Stat = tonumber(fibaro:getValue(114, "valueSensor"))

If thats any help

It can be read in lua with

Is it a sensor readout or a temperature setting in HRT4-ZW?

Regarding the solution, I actually can implement it without linked devices.

/emoticons/default_icon_question.gif" alt=":?:" /> Is my understanding right that HRT4-ZW can execute associated relay (f.ex. Fibaro switch) when the temperature is below set in HRT4-ZW? So in the same way as linked device works in HC2 ?

If yes, than the solution will look like:

- Associated HRT4-ZW's actuator is electrical valve connected to relay (Fibaro Switch). So HRT4-ZW takes care about the valve.

- Heating panel > Standard mode: LUA sets the temperature on HRT4-ZW according to conf in heating panel.

- Heating panel > Manual mode: activated by a new temperature set up in HRT4-ZW, Manual mode is active for n hours defined in a global variable MANUAL_TMT, than activates standard mode again (by LUA).

The manual mode did not work that way last time I tried. Manual works from heating panel but if you change at wall stat, the value is reset by hc2 within 1 minute. This may have changed in latest version.

[ivan.ruban 3]

My plan was to have a scene

Please login or register to see this image.

/emoticons/default_icon_exclaim.gif" alt=":!:" /> that:

1) Triggered by HRT4-ZW change (as soon as we set the new temp on HRT4-ZW)

2) Then LUA code runs in scene

• a. activates manual mode (so HC2 will not disturb HRT4-ZW any more)
  b. sleeps MY_GLOBAL_VAR_MANUAL_MODE
  c. activates standard mode

Won't it work?

Hmm, do you mean that despite of the fact that you activated "manual mode" in heating panel, HC2 still continued to override temp setting in HRT4-ZW? Is it the case?

[robmac 173]

That may work. You may get a very rare state when the job that resets changes the value back between trigger and reading in Lua.

Please report how you get on. I believe heating panel works by running a cron job every minute.

OK, so I've followed the instructions carefully to incorporate my HRT4 into a heating panel and associated a room and zone. I also used the "N" setup option to wake the thermostat up.

However the HRT4 does not respond to the heating panel settings, even though in the devices page it appears to be waiting for a wake up to go to the new setting. I have set the wake up interval to 300 as suggested in these and other forums. The HC2 receives updates when the set point is changed manually at the device.

I have tried removing, resetting and then reinstalling the HRT4, restarting and re-powering the HC2 to no avail. On the surface it appears to be a failure of the HRT4 to wake up!

A Remotec ZTS-100 thermostat (also battery operated) configured in a different heating zone but in exactly the same way as the HRT4 behaves perfectly.

Any suggestions?

Please report how you get on

I haven't implemented this scene yet, it is still in the plan. But I have another scene that is triggered by an opened window and which moves HC2 to the manual heating mode (10ºC). It allows to turn off radiator when the window is opened, then it comes to automatic heating mode as soon as window is closed again.

However the HRT4 does not respond to the heating panel settings

As soon as I included device and configured it in N-mode, it went well to configure a heating panel. You need to follow instructions here:

Don't forget to assign a heating panel to a room. It is not obvious in HC2!

The HC2 receives updates when the set point is changed manually at the device.

This sounds as the device is configured correctly in HC2. But at the same time you write:

On the surface it appears to be a failure of the HRT4 to wake up!

I did not have this problem in my case in the beginning and I have "network" icon on the HRT4's display. But it was very complicated to include and configure association of the device in HC2.

In my case thermostat was working fine for almost a week. But since yesterday, I also got a problem!

/emoticons/default_icon_sad.gif" alt=":-(" /> Device says "Waiting for Wakeup" all the time in HC2 and HC2 does not react any more on manuall setting of temperature on thermostat. The "network" icon is still on the HRT4's display by the way. Heating panel does not work either now since HC2 waits for a wakeup all the time and cannot transmit new temp setting. Thus it seems that Secure thermostat is still not fully compatible with HC2. In my case nothing changed yesterday except of I played a bit with readding and reconfiguration of Fibaro door/sensor device. But I don't think it is connected in some way.

A Remotec ZTS-100 thermostat (also battery operated) configured in a different heating zone but in exactly the same way as the HRT4 behaves perfectly.

Remotec ZTS-100 is quite expensive as I can see. Did I get it right that it works perfectly? It is good to test it then.

Do you know if this cheaper thermostat (

) will work in HC2? I haven't found any information regarding that on the forum.

Any suggestions?

No unfortunately. I will bet again that Secure thermostat is not fully compatible with HC2 yet. As I wrote - it worked perfect in my case for some time but now I also have "waiting for wakeup" problem.

Hmm... Since my last post, the Secure t'stat has started behaving itself (at least for one cycle!) and the Remotec is misbehaving

The CT100 thermostat you reference is similar to the Radio Thermostat CT30 that I have been using on wi-fi with Vera, and I was not aware of its existence. Not sure if it works with HC2 but there has been reports of issues with Vera (see

).

The other issue with the Remotec and the CT100 is that they offer there own schedule and heating and cooling. HC2 only supports the Remotec as a simple thermostat, and it would be desirable for them to be supported to their full capability similar to Vera.

What did you do to make Secure thermostat working?

The most interesting and funny thing is that since yesterday my Secure thermostat also started working! In my case I did nothing with thermostat. It is still mysterious for me why it started to work.

When I came home yesterday I checked the thermostat in HC2 and it was still "sick". Then I played a lot again with re-adding and re-configuration of D/Window sensor (

Please login or register to see this link.

). Then when I checked thermostat a bit later it became alive! Now it also reacts again on manual temp settings on thermostat.

I don't understand how it can be connected to readding of D/W sensor. Reconfiguration of route to thermostat via d/w sensor? No, I don't think it is the case since thermostat is located 5 meters from HC2. How far is yours by the way?

I have 2 possible professional explanations for that:

• 1) It's a kind of magic
  2) There was a right phase of the moon yesterday

ZWave and Fibaro still continues to suprize me every day.

/emoticons/default_icon_biggrin.gif" alt=":-D" /> I will bet on the moon (option 2) since both mine and yours thermostat became alive.

P.S. CT100 will most likely not work in HC2.
