Remeha Calenta

It has been a while ago since i worked on this project. After the new central heating had been installed in the first week of april, i spent time to get the combination of Remeha Calenta, Remeha Gateway and Remeha Celcia 20 to work. I failed…

Somewhere there is an unstable factor in this combination that makes these 3 devices not work together as they should, and as was stated that they could by a Remeha technician. So i put this project on hold for a while. But now that holidays have started, and the days will get shorter in a matter of weeks, i would like to have this project finished by the time  we need the central heating again…

Last week i talked to the  person who installed the Calenta and he asked me to write down all my problems in an email that he would forward to Remeha Technical Services department, to see if it was possible to have a Remeha technician coming over to my house to investigate the problems i am having.

After integrating lights, appliances, garage doors, alarm systems, TV, Home theatre, music, the largest piece of equipment that is not yet integrated is the central heating. That has to change… one way or the other!

All kinds of things are made possible these days in this area, just look at the Danfoss Z-Wave controlled radiator thermostats for example. It’s a sign you can’t ignore. So i hope Remeha has a clue of what is going on in terms of Domotica & HVAC; and i hope they inderstand that the systems they produce can no longer be isolated from the rest; it’s time to connect!

Next wednesday i have a Remeha representative coming over to my house to see what’s the best heating system for our house. Remeha has got a new model since recently, the Remeha Calenta. Probably with a much higher price than the Avanta, my choice so far. Another very important issue is that the Calenta needs to have the ability to be operated with the Remeha Gateway just like the Avanta. The recommended thermostat for the Calenta does like very nice, BTW. And maybe i’ll add a solar water heater to the system, who knows. Alot of questions, hopefully to be answered next Wednesday.

Today i found this ad in a magazine:

175 Euro discount on the Remeha central heating of your choice. It’s time for the next project

Yesterday we got a letter from the company that does the maintenance of our central heating. It said our current central heating was to vulnerable to failures and we were offered an upgrade to a newer central heating at a reduced price. Well, it is true that our central heating has caused us a lot of trouble through the 10 years that we live here. So i understand the reason why they want us to upgrade to a newer model from a different brand. But i’ve got my own wishes…
Our new central heating should be controlled by means of the Opentherm protocol for instance, so that i can ‘tap’ the communication between central heating and the thermostat and incorporate the data that i can get out of that, into my Domotica System. And i’ve made my choice: our new central heating will be a Remeha Avanta, controlled by a Remeha Celsia 20, including a so-called gateway for attaching a RS-232 cable to it and tap the communication.
