HVAC: Digimax or RFXCOM?

Post by **chrispazz** » Thu Aug 20, 2009 3:27 pm

Hello.
I am using a SC9000 security console and a standard weekly programmable thermostat.

I would like to connect temperature HVAC control to my X10 network.
I have two options:

- buy a Digimax unit and connect it to my SC9000 (is it surely compatible)?
- buy a RFXCOM receiver and a Oregon Scentific temperature sensor.

Which is better? I am using Indigo with an always on mac computer.
In both cases, if I am right, I have to buy also a UM-7206 to control my heating system.
Thank you
Chris

Ciao , se hai la sc-9000 e vuoi controllare i termostati , non credo che tu lo possa fare perch ti gestisce solo la security e le utenze elettriche, in pratica non ti gestisce un segnale temp. od HR% . Prendi i sensori Oregon + rfxcom + un controller tipo CTX35 con Homeseer. ( in pratica rfxcom , riceve i segnali delle temperature , li fa elaborare ad HS e questo tramite la ctx35 manda i segnali alla caldaia. attenzione che se usi una a gas metano il conitnuo accendi/spegni elettrico la potrebbe rovinare....).

Ciao Lorenzo..... raro vedere un italiano appassionato!!!!
Bene, io sto gi usando Indigo con il mac e supporta RFXCOM nella modalit a 32 bit.

In realt girando in rete ho scoperto che la SC9000 dopo una certa data di fabbricazione supporta anche il digimax, anche se non so esattamente come capire da quando.

Comunque pensavo anche io di propendere verso RFXCOM visto che mi apre la possibilit di fare molte piu' cose.
La mia caldaia a metano ma pensavo che potevo creare qualche script per fare in modo che il tempo minimo di accensione/spegnimento non sia inferiore ad una certa misura per evitare danni....

PS: hai trovato qualche shop economico dove prendere l'hardware x-10?
PPS: stavo pensando di prendere l'RFXCOM con doppia frequenza per usare anche gli apparecchi USA a 310MHZ che costano molto molto meno. Hai esperienze in merito?

Ciao ciao!

Hy Christian , about Mac + Indigo i can not help beacuse i'm a "poor" windows user

. About sc-9000 i've never heard of a batch production capable to support Digimax. I think the best if to use RFXCOM, USA version too ? I have some doubts because hw is less expensive, but consider ship costs , taxes ... i planned 2-3 times USA shopping , but i've always found a FINAL worst price (different if you travel there and put all in you luggage.....) . About script to delay the "not necessary" on/off that's a good way. If you need some HW -x10 from Italy , i can have some discount from a reseller. Send me a PM.

Hi drmacchi, I cannot send you PM because I have not sent enogh messages in the board.
Pls send me in PM your email and I will wrote you back.

However, buying from USA is really cheap only if you buy large amount of devices. You can pay on ebay 4/5$ for a MS14 unit and so on.

Thank you.
