Is ELV Max! a reliable system compared to FHT80b (or ZWAVE)
Posted: Wed Jun 19, 2013 8:54 pm
I was wondering what the experiences are with users of the ELV MAX! system? Is it more reliable than for example the FHT 80b's?
I am looking to upgrade my current heating system (which uses FHT80b's). It works OK when you don't touch it, but there are irritating issues:
-The system is not fully bidirectional. You can send a command to a FHT80b thermostat but there is no feedback whether is has been received (other than waiting a couple of minutes to get a status update);
-At times the system seems to upset itself, resulting in total lack of response to anything something for half a day up; Quite irritating if you come home in winter and the house is cold
-Response is quite slow. You can send a command every two minutes, but frequently they do not arrive properly. So it can sometimes take up to 15-30 minutes before the valves react;
ZWAVE doesn't seem to have these problems (bidirectional and autorouting), but Danfoss thermostatic valves seem to be the only possibility are they are not very cheap (if you need 9 of them).
I wonder is MAX! also doesn't have the mentioned problems?
-Is it bidirectional (commands sent are always received and reacted upon)?
-Does it keep on working for a longer period?
-Is it more responsive than FHT80b, e.g. it doesn't take 15-30 minutes to get a valve to react?
-And lastly, is there some signal in the MAX Cube that heating is needed? This because I have city heating and I need to open/close the valve which circulates the hot water.
Or is ZWAVE the better solution? And are there alternatives to Danfoss?
Hope someone can shed some light to the subject
