This describes the way to include The Horstmann HRT4-ZW (thermostat) and the ASR-ZW (relay switch) into Vera and to make the both devices work together without Vera. A big part of the credits go to user ‘Turk4U2’ which made an instruction which I used and tweaked.
Note that this instruction has been written with the use of a Vera Lite with UI5 and firmware version 1.5.622. I’ve read many other instructions which were written for lower Vera versions, lower UI versions and lower firmware versions. All of these instructions didn’t work for me, hence this instruction.
Also note that the Horstmann HRT4-ZW and the ASR-ZW are being sold today as a ‘Secure SRT321’ (Thermostat) and ‘Secure SSR303’ (relay switch). This is becasue Horstmann is part of the secure group (see www.securetogether.eu).
Before you start with anything, configure the thermostat and relay switch BEFORE you install the thyem into your house on the proper place (thermostat at the wall in the living room and relay switch near your heating system). It is way more easy to include these devices in Vera if you have your Vera attached to the network (other then running your Vera in battery mode to include). Also, don’t pair the thermostat and the relay switch according to the manual of the manufacter as this instruction is not ment to include the devices into Vera (or any other z-wave network/switch like Vera). If you happen to pair them according to the user manual, no worries. You can go back to the factory settings by doing the follwing: On the HRT4-ZW put DIP switch 1 to 1; Use the Dial to go to ‘P’; dubbel click the Dial; put DIP switch 1 back to 0. Now you can start with the instructions below.
Adding devices to Vera 3 or Lite:
HRT4-ZW:
DIP-switch 1 on 1
turn the wheel to put the HRT in learning mode (L)
put Vera in include mode (varies per Vera (Vera3 or Vera Lite))
push the wheel so the L blinks and the ZWAVE LED on Vera blinks fast and stabilizes to blink slowly as confirmation of the include
finally put DIP-switch 1 back to 0
The device is now visible in Vera and can be configured by putting it in the LI mode
The device is shown in Vera as “_Horstmann Radiator”
Now some last configuring before going on to the ASR-ZW…
DIP-switch 1 on 1 again
Putting it in the LI mode avoids having to wait for the device to wake up to be configured, it LIstens.
Putting wake-up period to 256, shortest possible.
All other settings are set correctly by Vera with UI5 (firmware 1.5.4 and above)
ASR-ZW:
put the DIP-switch 1 to 1 on HRT4-ZW (not sure if this is needed, but this is what I did. It doesn’t harm to do so…)
Power it up and waiting it’s to be included as any ZWAVE switch (like Vera). Some ASR-ZW will let you show a blinking network light, not all will do (have no idea why…)
bringing Vera to the ASR and put Vera in include mode (varies per Vera (Vera3 or Vera Lite))
now pushing the ZWAVE button on the ASR (this can be seen, but not always: ASR will stop the blinking of the ZWAVE LED on the ASR and cause fast blinking of the ZWAVE LED on Vera for a second. The green ON LED blinks a couple of time on the ASR and ten the red OFF LED remains on as confirmation that the ASR is included.)
If you include vera through the webinterface (which I did) then it might be the case that nothing is happening. Use the “I’m activating the device, but it’s not adding to the list” option.
In my case, the network light on the ASR-ZW started to blink red and Vera included the ASR-ZW
The device is shown in Vera as “_Horstmann Relay”
put the DIP-switch 1 back to 0 on the HRT4-ZW
Associate the Themostat (HRT4ZW) to the Relay switch (ASR_ZW):
Now, both devices are know in Vera, but they as not paired with each other. But, since both devices are in Vera, we can do this through the webinterface of Vera.
Go to ‘Devices’ in Vera and click on the wrench of the device “_Horstmann Radiator”
Go to ‘Device Options’
Scroll down and you see the sub-section ‘Associations’
At Group ID you type 1 and press ‘Add group’
Now you have a group for the “_Horstmann Radiator”
We now have to associate the “_Horstmann Radiator” with the “_Horstmann Relay”
We are still at the sub section Associations and at ‘Group ID 1’ we press ‘Set’
Now scroll to the device “_Horstmann Relay” and check it (click square)
Now scroll all the way down and press ‘Back to ZWave options’
Close the settings page of the “_Horstmann Radiator” (top right, click x)
Press save (right top in Vera web interface)
Now, put the DIP-switch 1 to 1 on the HRT4-ZW
Putting it in the LI mode avoids having to wait for the device to wake up to be configured, it LIstens
Go to ‘Devices’ in Vera and click on the wrench of the device “_Horstmann Radiator”
Go to ‘Settings’ and click ‘Poll now’
The “_Horstmann Radiator” will now be updated with the proper settings (wait for Vera to
say that the device has been polled correctly)
Now, put the DIP-switch 1 back to 0 on the HRT4-ZW
Ok, this is it. Now you can test your heating system. It should work with the HRT4-ZW (this is instant) and with Vera (this can take up to max. 256 seconds).
Thanks a lot for the description. I am considering to buy the Horstmann thermostat, but would like to use another type of relay (the new Fibaro Wall Plug). I presume it would be no problem controling the Wall Plug thru Vera, but do you know if the Horstmann thermostat can be paired with a non-Horstmann relay (as the Fibaro) and still work without the Vera?
I have a Horstmann HRT4-ZW directly associated with a Fibaro FGS211 switch module. I first included the HRT4-ZW to Vera and then used Vera to make the association to the FGS211. The HRT4-ZW controls the FGS211 directly and I use Vera to set the temperature setpoint as required.
[quote=“davkav, post:5, topic:175197”]I just want to add that the cheapest place I found the thermostat and relay together was from BES Plumbing Supplies
Other sites are considerably dearer so just thought I would help out fellow MCV users.[/quote]
Thanks for this! I cant belive the price difference between this site at others. I purchased the ASR-RF from Vesternet (Awesome guys btw) for ?64 but never bothered with the thermostat as they want ?156 for the AS2-RF alone. On BES they want ?88 + VAT for both! I might consider the AS2-RF now as a backup controller as oddly now my internet connection has died thanks to BT and migration issues from BT to BT, the vera seems to not bother to send z-wave commands to my ASR-RF. I am not home to diagnose the issue and with the line down i cant remote in, so having the AS2-RF for ?44 as a backup on the wall somewhere to straid control the heating/water now makes sense as i cant rely on vera alone for that. Thanks so much for this link!
I have an additional question about these products. Would it be possible to connect three receivers to the thermostat.
I have in my small business 3 natural gas heated blowers which I like to control throgh Vera.[/quote]
I have no idea if you can associate 3 HRT4-ZW’s to a single ASR2-ZW. Have a word with the guys at Vesternet, they have always been pretty helpful.
You can however associate the 3 HRT4-ZW’s and the ASR2-ZW to the vera independent of each other and have either scenes or for greater flexibility use PLEG to handle the logic as to when to turn on/off the relays in the ASR2-ZW. I Just have the ASR2-ZW and in various rooms i have temp sensors and then use PLEG logic (http://forum.micasaverde.com/index.php/topic,16176) as to when to turn on the heating or hot water relays. The HRT4-ZW’s are a “nice to have” for me but manual control might be a must for others.
I have used the evening trying to get my Secure SRT321 to control my Fibaro Wall Plug FGWPF-101, but with very limited success (none at all to be honest).
I have tried to follow the description, and as far as I can understand, the thermostat is integrated into Vera correctly. I can select new setpoints from the Vera UI, and I do see setpoint changes that I set directly at the thermostat wheel.
I can also turn the heater (wall plug) on and off manually thru Vera or by using scenes.
In the thermostat’s “advanced” tab, I see a line “ConfiguredAssoc 1,40”. 40 is the device# of the wall plug.
However, even if the flame symbol is displayed in the thermostat’s small LCD, the wall plug does not turn on.
Do I have to configure the wall plug in any way to respond to messages to group #1 from the thermostat?
I’m running out of ideas here. Any help will be appreciated.
Have a look at the Vesternet link I posted above there is a section on Association. Creating a link (via a group) between the thermostat and the relay/socket might be what you are after…

Yes it is, and thanks a lot. I had them associated already, but the culprit was that I had associated my Fibaro Wall Plug in group 1 per the instructions for the Horstman relay, but my device is controlled in group 2 it seems.
So now I think it works (using group 2). I haven’t really put it to use in the kitchen yet, it’s still in my workshop with my Vera Lite, but within a few days I will reach a verdict.
Just to clear up the confusion on the Association groups.
The SRT321 (HRT4-ZW) reports different types of commands to the various association groups.
On group 1 it reports Thermostat Node Set commands - so the device you’re reporting to must be set to accept these commands.
Group 2 sends BASIC Set commands, this is more versatile as every device can accept these.
In the Vesternet guide I used Group 2 but Group 1 works equally well, as the Secure Receiver accepts both commands.
One other point - using Group 1, the SSR321 can be associated with four devices, but for the other groups can only be associated with one device.
So in the case of Fred’s question, you can associate one thermostat (HRT4-ZW) to up to four receivers (ASR-ZW/SSR303) if you use Group 1 association.
The full list of groups is:
1 Nodes controlled by Thermostat Node Set command
2 Nodes controlled by Binary Switch SET command
3 Nodes to receive unsolicited Battery Level Reports
4 Nodes to receive Thermostat Set Point Reports
5 Nodes to receive unsolicited Sensor Multilevel Reports
Just included the hrt4-zw and asr-zw into my network, and have noticed that vera lite on ui5 is reporting the temp as one degree higher than on the hrt4-zw.

Yup. Mine does this too.[/quote]
Is it an issue with vera or the hrt4-zw?
Any way to fix it?
I can't be sure but I think it is the HRT4-ZW display that is wrong. It sends the heat command when the setpoint is above the room temperature that Vera shows rather than when it exceeds its own display value.
Any way to fix it?
Not that I know of but why is it causing you a problem? As long as it switches reliably does it matter what value it displays on its LCD screen?

My one seemed to display the same value at the LCD as I saw when checking my Vera’s value using my phone yesterday evening. They both read 20.
I have however not performed any lenghty test using different values. As these are integers, perhaps it could be a matter of rounding? Perhaps 20.9 is still displayed as 20 but Vera might call it 21. Just a thought.
Finally got around to order one of these Horstman HFT4-ZW Thermostat and receiver as it is only 68,38GBP including VAT at the moment at BES (bes.co.uk).
Quite a nice price considering it is around 100GBP from other shops…
It seems that the status of the ASR-ZW does not get updated to my Vera every time. I have set the “Poll this node at most once every” to 30 seconds but it does not seem to help.
How short can I set the Poll interval? Any recommendations? The status updates to the correct value if I use the “Poll Now” button.
Are there any Device Option parameters to enable the device to spontaneously send the status as it changes? Seems like a waste of resources to poll the device to often.
