I spent already few hours digging on google and on this forum and I’ve got a question regarding usage of items from topic.
I already bought Horstmann ThermoPlus AS2-RF kit which include AS2-RF and ASR-RF but I didn’t realize that it’s almost not possible to use it with Vera 3 (I know that manual exists [url=http://forum.micasaverde.com/index.php/topic,1632.msg26366.html#msg26366]http://forum.micasaverde.com/index.php/topic,1632.msg26366.html#msg26366[/url]) so I’ve got few questions:
Imagine I will pair successfully AS2-RF kit to Vera 3. Will I be able to control heating from both Vera 3 (setting the temperature) and thermostat (by using + or - buttons)?
The AS2-RF and ASR-RF will be operating without Vera 3? For example I will set 7 days program on AS2-RF, it will be controlling ASR-RF without issues?
I’m expecting that I can receive both No for above questions so I’ve got still few days to send it back to shop. In this case I’ve got few more questions:
I can buy HRT4-ZW and SSR302 and it will be working properly? I seen manual available on both forum and Micasa Verde wiki but it’s better to ask again
I’m not sure of the difference between the AS2-RF/ASR-RF and the normal Z-Wave versions ASR2-ZW/ASR-ZW, but it looks like they were designed as a closed system.
Both of the Horstmann/Secure Z-Wave controllers can be used in VERA - these are the ASR2-ZW (SSR-302) and ASR-ZW (SSR-303) and work very well with the thermostat HRT4-ZW (SRT321).
This is the combination i always recommend for controlling heating with VERA.
The SCP318 is again a special case, it only uses Z-Wave to communicate with the receiver, but cannot be added to a VERA network (or any Z-Wave network).
[ul][li]HRT4-ZW to control temperature from both Vera 3 or by manually setting the temperature using wheel?[/li]
[li]SSR-302 or SSR-303 to control boiler receiver[/li][/ul]
and all elements will be working without any problems?
I read your blog post about creating scenes for heating and I’m a little concerned. There is an information about Fail Safe:
For instance, if you turn on the receiver via a Scene, then it will automatically turn off after 60 minutes. Therefore, for these types of scenes we recommend that you send additional 'On' commands to the receiver every 30-45 minutes.
which means that I should sent additional ‘On’ command every specified time but it was not described in building scenes.
Hi yes the SRT321, SSR303 and SSR302 work well with VERA.
The failsafe mode is an issue when you are controlling the SSR303/302 directly from a scene - by turning it on.
If you are using the SRT321 this is not an issue as the thermostat ‘pings’ the receiver every 45 mins or so. Therefore for heating this should not be an issue as you will use the thermostat associated directly with the receiver - http://www.vesternet.com/resources/application-notes/apnt-20
The scene used in the guide is for heating.
If you use a scene to run the hot water, you would need to take Fail Safe into consideration and have a part of the scene send an off/on command every 45-50 mins. But normally you don’t tun your hot water on for long periods of time, so this should not be a large issue in the scene - you would probably have to do it once.
This type of scene control would probably be easier if you do it using the PLEG plugin as it has much control of scenes.
The alternative would be to us a Fibaro Dual Relay (FGS-221) this will control the heating and hot water systems, the relay doesn’t have manual control buttons, but you could easily add an external 2-gang switch to it for manual control of the relays.
I use an ASR-ZW directly controlled by Vera but using PLEG rather than scenes. To accommodate the failsave feature, I have a schedule that runs every 30 minutes that triggers a condition to resend the last mode. Something like this:
Schedules
I30M Interval 30m
Properties
HWRelayMode Hot Water Relay ModeTarget
Conditions
_HWPulse I30M
Actions
_HWPulse Hot Water Relay SetModeTarget NewModeTarget={(HWRelayMode)}
I don’t know if it is supported by Vera yet. It looks as though it has the Z-Wave capability to be included and controlled. Why do you need the programmability if you intend to have Vera manage it? People have found difficulty with some other programmable thermostats because the programming overrides commands from Vera. YMMV.
For me it’s not a problem but for my wife it’s an issue because she just want to control temperature just like normal thermostat - button clicks I ordered HRT4-ZW so she will need to learn how to use Vera
Your wife will be able to set the temperature on the HRT4-ZW. It’s up to you when Vera sends setpoint changes. In my system it is controlled by PLEG and setpoint changes happen as a result of time schedules and other events. So if I decide to crank the temperature up a few degrees in the evening, it will get reset to normal nighttime value when I go to bed.
I’m in the same situation. I ordered a Horstmann C-STAT 17-ZW as my wife likes to control the heating via a “real” thermostat with buttons.
I tried to configure it on my Vera Lite and although the thermostat (SCS317) and ASR-ZW receiver (SSR303) are detected, I cannot associate them. I used the same procedure as for the HRT4-ZW but my CSTAT 17-ZW does not have dip switches, so I couldn’t change those.
I’m in contact with Secure / Horstmann en Vera to get some help.

Hello can you provide a bit more detail on this for a newbie please I am trying to do this but struggling with PLEG
Start by setting a Schedule named I30M as an Interval every 30 minutes. Create a Device Property named HWRelayMode for your relay device’s variable ModeTarget.
Add a Condition named _HWPulse with the expression I30M
Add an Action for condition _HWPulse, select the Advanced tab and pick your relay device. Select the action SetModeTarget and under NewModeTarget enter {(HWRelayMode)} then click Accept. Close the PLEG control and click Vera’s Save button.
What should happen is that every 30 minutes - on the hour and half-hour - PLEG should send the relay the last mode it was set to. This should cause nothing to happen apart from seeing the notification on the relay’s UI that the transmission was successful. What it achieves is that the relay knows it is still being controlled and does not perform an emergency shutdown.

Hello,
I’m in the same situation. Did you find the solution ?
I’ve got quite a few options in my place. Smart Virtual thermostat in one room, HRT4-ZW in others and the C-Stat 17-ZW in the main lounge.
The c-stat 17 is menu driven. in the setup, you can associate the 'stat with the heater switch that way. Just choose “Associate node” and it goes into a learning mode (just like flipping the dip switch on the HRT4), then press the network button or a couple of presses on the switch. That should be it.
I also think there is a way to set the associations in vera under the device properties, but i haven’t had much luck with that so preferred to do it locally.
Let me know if you’re still struggling and I’ll go into a bit more detail.
Great devices though, love them. i just need 2 more for other rooms.
Thanks for your answer.
I have associated them. I made a tutorial. I put the link but sorry, it is in french : howto install
I’m disappointed because there are a lot of buttons available in the browser but only the temperature can be used.
I found a disfunction : if you activate the SSR303 manualy (or via the browser), the SCS317 loses the hand on the receptor (SSR303).
For example : TM = temperature mesured & TA = temperature asked
TM = 21 & TA = 19 (TM > TA) so the receptor doesn’t heat. I push the “on” button into the receptor. That’s heating.
Now if I put TA = 17 on the SCS317, the receptor doesn’t swith off.
If I don’t touch to the receptor, manually or via the browser, that works very well.
Another question : do you know where we can find the parameters you can add or modify ?
I am new in this and have a small question relating the HRT4-ZW. I live in a building, and in my apartment I have several radiators, and one analog thermostat that controls the on, and the setpoint of the temperature. I am not sure the system they use to control the heating on the building, but I wanted to know your opinion on if this product would work for me.
I know it is little information but it is all I have for know. I will try to get more information regarding my building infrastructure for heating system.
