Since this year we use the eQ-3 MAX! Electronic Wireless Radiator Thermostat to regulate the heating for each room.
Some Dutch energy suppliers offers this product types (Essent E-thermostaat) but it’s main disadvantage is the control over the whole house and not the regulation per room. And we like to be more or less independent from the energy suppliers so each year we can select the cheapest green energy.
In this post a short description of the eQ-3 MAX! Electronic Wireless Radiator Thermostat with some pictures.
Above the original situation; a thermostatic Amfratherm radiator knob.
The radiator knob unscrewed, as you can see no heating water needs to be drained. The worm size was different from the eQ3 and the supplied adapters didn’t fit.
So I’ve checked the sizes and ordered at Conrad the Messing adapter Markaryd. This one didn’t fit properly but with some filing I managed to place it properly.
After placing the eQ-3 gave a “F2″ error, wich I also had with the eQ-3 time controled radiator. In this case a € 0,05 coin also gave a solution.
Hereby the eQ-3 installed, the display (ADA) shows it’s in setup mode.
Above the Eq-3 gateway installed near the router.
The Windows PC app is fee to download and is easy to install. For each eQ-3 you can specify the room, or even several eQ-3 MAX! Thermostats. With this app you allow use from internet with your own eQ-3 internet account.
For each room you can setup a time schedule Above its on monday standard 15 degree (Celsius). My daughter wakes up at 7:00 and around 7:30 she leaves here room. So in the morning the radiator starts at 5:30 (well before the central heating starts) until 7:00. The left-over radiator heat is sufficient until 7:30.
In the afternoon around 16:00 she comes home and will have a drink downstairs. So around 15:00 the pre-heating starts at 19 degrees and between 16:30 and 20:30 the temperature is set to 21 degrees. Around 21:00 she goes sleeping so 30 min. before the radiator goes to 15 degrees.
If you allowed public internet traffic on the gateway it’s possible to regulate adjustments via http://max.eq-3.de on your own eQ-3 account.
An iPad / iPhone app is available, above a screenshot. This works fine, only disadvantage: it’s only in German language. Also for Android an app is available.
The experience with this eQ-3 products are ok. eQ3 use it’s own communication protocol so combination with other domotica products like Klik-aan-klik-uit or Plugwise is not easy. eQ3 offers some extra products like zoals window sensors, extra switches etc.. Take a look at the eQ-3 website, Conrad or ELV.
Below an overview of the connections at my home for the heating.
