Experience with automatic radiator valves?

[Tijseling]

I am very interested in the honeywell evotouch products, so i will follow this topic.
the uk website of honeywell allready has more info on the system, and it says the usb cabel is for a connection to a pc. so i would say there will be more functionality for use with a pc. maybe graphic way of programming zones and schedules to the evo touch.
if it was for programming new features to the evotouch, it would be a "servide thing" and would not be very important to tell about it on the website. i'd say.....
it also works with opentherm if you get an opentherm receiver/conversion device so that would be nice too, if not to expensive....

Well i hope to get the evotouch before the weekend but might be next week.
( its posted and some where between germany and holland )

Main reason i bought it is because i needed one controller extra ( got 3 zones ) and then this one came along. I might be to focused on the usb port, as it state for future updates ( wich could be everything ). But to me that reads like it is possible to openup the device and .

I am willing to undo the device from its housing and make some pictures to identify the electronics/jtag if that does any good to anyone.

I mean i broke enough to know its better to keep things closed if not needed to openup ;o)

exactly my thought...
more zones is allmost impossible to setup with only one thermostat. it needs a complete homeautomation system which is to expensive and would be overkill to me.

I have a new house, and the ground floor has floorheating, and 1 radiator near the front door in the hall.

upstairs are 3 rooms with one radiator each, and a bathroom, in which i plan to install floorheating, and 1 design radiator ( is that even neccesary if i put in floorheating there?)

then 3rd floor, ( attick) which is quite big, and could become a study or 4th bedroom or something..

then i would have 1 or 2 zones downstairs, bathroomzone, and at least 1 bedroomzone, and at least one zone in the attich. i dont need a thermostat/clocktimer etc in every room, and communication would then be wired, or with a lot of stuff to be installed. (wireless valves, thermometers/more thermostats, clocks, etc)
with evohome i just needs 5 radiator valves, a receiver, thermostat, opentherm device, and maybe a pumpswitch. i can start with minimum zones and expand when needed.

since you actualy allready bought one, what do these things cost, and where did you arder from? they are not for sale in holland yet?

i believe evotouch/evohome are introduced at the VSK conference in holland februari this year ?

would you know anything about this thing being able to work with ventilation fanboxes like the ones from buva, or itho? or if it works with air/air or air/water "warmteterugwinning" devices such as daalderop combinair, ecolution, etc? the honeywell vision can switch ventilation, but i believe those ventilation units used here in holland are all not compattible... i would like to ditch the stupid wall mounted switchingbuttons next to the themostat.. It would look better with just one thing attached to the wall, or maybe even just one device sitting on the table or so.

Well also keep us posted about any experiences with the evo...

Well dont confuse the cm67z controller or evo touch with a thermostate as in my case the hr80 valves are the thermostates.

The HC60NG can controll a lot of devices (24v/230v, hot and cold) i have seen in the manual . But as i am expierenced thru my own expieriences so i am not an expert on heating or hvac devices.
I daily life i am a designer of gfx, and i am redesigning my city heating system

As i got city heating thats opened or closed with a mt4 nc24 from honeywell so that was kind of easy. Hookup 24v to the relay ( wich the hc60ng is ) and make it open and close the mt4 24nc
( 24v on this thing opens up after a few mins... and no electricity makes it close again )

It should be possible to hookup more than one relay (hc60ng) so its should be kind of flexible. An expert could tell if the mentioned devices can connect if you show the manual of the HC60NG.

About the VSK you are right, it should be introduced there and there even might be more info about the future updates.
I bought the evotouch controller in germany here : for about 230 euro

ok, but you have allreay got two zones with 3 hc80 and one cm67z
cm67z only does 2 zones, so the hc80 is a thermostat, but does not do any timeschedule byt itself, just temporary overrides.

so.. no more then 2 zones possible realy.
i meant using one cm67z for each 2 zones you would like to program. that would be very expensive, and allmost for no other reason then honeywell does not want to sell it to you cheaper.

for floorheating there ore devices that con control 5 groups with one clockthermostat, and you could add hc80's to those groups.

hc67z gas a free contact, which you can steer a on/off device with, ( like servomotors, or pump) but there is a maximum of wired device you can switch per contact, i believe 3..
but dont know.
and they would be wired.

so evotouch is much easier.

for me at this moment i would need 1 evo touch, and 4 or 5 hc80 = almost 900 euro's if i would do it witch the floorheating solution+hc80+boilerreceiver, antenna, it would be over 1300.

[Tijseling]

someone sent me a private message, but i am not allowed (yet?) to read them?

[r_255]

That was me, with a link that i posted already here in the topic.
In this image you can see the one or two way communication between the devices that you can connect. Also seperate thermostates or outdoor sensors etc... just check the honeywell part numbers in google.



Stuff like hvac, heaters boilers you connect to the HC60NG wich is controlled wireless but the last part to your heater or airco is wired as you need to switch 24v or 230v.
Prices you mention are way to high, like 600,- for the mentioned 4 valves and a evo are closer.

[Tijseling]

i would like to connect to a open therm central heater. and the mixer device, what is that used for?
to connect a floorheating system with all groups in one zone? so that it will stear the pump, and control the mixing of hot water with retourwater?

[r_255]

Sorry to say but thats a question i cant answer because i dont have the knowledgement, just call honeywell and ask. They where quite helpfull the times i called them.

Today the evo controller has arrived and i hope to post my disection pics tomorrow.

1st impression, nicest design i have seen from Honeywell. No mounting frame or feet to put it on. ( sold seperate )
and there is some space for a expansion bord/module on the back ( seems like )

The bord is driven by an atmel processor so i got some hope.

so now lets try to install linux on to it

[r_255]

Wel embeded linux or even wince should be possible on this platform, but that doesnt make it a cm zone controller thats controllable by pc.

Next steps are:

- See what kind of development tools are available and try to find out what honeywell might have used for this device.
- Make a rom dump and try to open it up with some development tools.

and if we know enough about the basics of the system we could hire some external knowledgement or can try to find out ourself.
The last one is kind of hard for some one like me ( got zero knowledgement about these things except for those things i have seen arround here )

I guess its the best to open up a seperate topic for this, as this isnt about automatic valves.
Pointers or sugestions are more then welcome.

But 1st i am going to finish my installation of the device, wich reminds me to say that a dock/stand is needed and have to be ordered seperate. The time span of the rechargeable batteries was about 16 hours the 1st time use. Before i got to this conclution

Installing was a breeze and navigating quite easy but before i got finished completly the batteries ran out.

Today i found out that Honeywell wil anounce more info on the VKS ( fair about plumbing/heating etc..) about the connectivity so we might wait a bit till after this VSK fair.
I have seen a press release where they state in dutch : ( tried to translate without google )

Also Future posebilities are revolutionary, services like weather forcasting, remote control from a distance , software updates that used to be only possible in proffesional building management systems are now all possible due to the intergrated usbport. On the Evotouch all these options will be possible in a regular house.

The only thing i want to know now is when and how
dutch source : regelvisie.nl/pages/Woningen/nieuws/evo ... ohome.html

[Tijseling]

souns nice those updates, but it does not say anything about control from a computer(program) by usb port, or monitoring with a pc.

then it would be super!

i have read on www.tweakers.net, that HP(?) had also made a sort of small computer with a touchscreen for homeautomation, and that there is another computer manufactor that had made a small pc for homeautomation function.
they are both with touchscreens, and have thermometer functionality.

but i have no idea about how sophisticated that software is. a thermostat realy looks like a simple device, but when it has to be self learning, and be able to switch opentherm etc, that realy is a specialty, and costs money for using the opentherm protocols i guess...

there were no releasedates of those devices yet, nor are there realy specifications, or prices... so i hope these things will appear in webshops soon.

well.. my dutch is as good as yours i think, so this translation was readable by me

[Tijseling]

after readin the whole dutch website, teh posibility to control ventilation etc with evotouch, would be very nice..

in my new house i have a thermostat on the wall. 15 cm next to the controlbox of the buva boxstream, with anoing bleu led.

then i can get rid of that stupid thing, and maybe even put the copntrol on a automatic schedule, so it wont make so much noise.

problem then is that i would get stuck with a hole in the wall... i just got it succo'd and painted yetserday....

but hey.. that canbe solved when time comes

Hi., guys what a nice information which you have posted, I am a newbie for this forum site.
Thanks
