When I built my own floor heating system, I used a regular switch actor and regular valves, as this unit wasn't available at the time. Looking at the description of this unit I'm a little surprised. Can't, for example, channel 1 not be used to switch on / off a pump? From the manual: ' Connect a hea...

I have both the older HM-ES-PMSw1-Pl and the newer HmIP-PSM-2. I noticed that my HmIP-PSM-2 always reports load of around 3.5 watt, even if nothing is connected. That seems to be wrong. The old ones were fairly accurate, and I could use them to monitor very low wattages, below 1 watt actually (at le...

I've given up on detecting a valve in CAL condition of my radiator valves (no matter what I tried, nothing works). So, let's focus on eliminating the CAL condition then. Anyone who has a good suggestion how to do that? In the past I've seen some suggestions adding a coin (doesn't work here, not enou...

I've put regular radiator valves in the loop, which works fine, though you might have to replace the firmware of the valves with an older version.

I had some experience with this behavior. Here's how I dealt with it: 1. Give each room its own thermostat, if possible. Then link that thermostat to the radiator valves in that room. (Controlling multiple valves in separate from a central point never works.) 2. INSIDE that room you can use the 'tem...

The radiators furthest from the boiler require a much larger valve opening in order to heat up vs the ones nearer the boiler. If I set the requested temperature to 30C for example they heat up fine. However for everyday use where the temperature is just below the requested temperature the valve wil...

I got no problem with that, but why not ship to the Netherlands? For clarification: not through Amazon.de. ELV does ship from their own webshop, but they charge quite a bit for shipping, whilst Amazon.de doesn't charge anything. Amazon.nl is a hopeless site. Many products are missing, and the prices...

A (former) dealer / reseller of Homematic informed me that EQ3 will discontinue with Homematic 'classic' though they will continue with Homematic IP. Remaining Homematic 'classic' products will be handled by ELV, for the time being. ELV did not want to resell products to this specific dealer / resel...

Yes, I just checked. Conrad lists them again, but now at an 'adjusted' price of 81 e incl. VAT... Oh well, at least they appear to be available again. (I send out an email message to ELV, I cannot order kits through Amazon.de, but maybe ELV will send them. I hope shipping is a bit reduced on larger ...

Is the HM-LC-SW4-WM (4 port actuator) end of life? I just noticed it's price doubled, and it is no longer available on some websites. I am using a few of these, so 90 euro for one is a bit steep, when they were around 40..50 euro before. (Just bought the last unit in stock from Conrad.nl, who now no...
