Ali lahko obdržite svoj pametni termostat, ko dobite novo klimatsko napravo?

Odkar so na sceno prišli pametni termostati, se jih lastniki stanovanj oklepajo kot klopi na dolarjev zadnji del. So odlični mali strojčki in res vam lahko pomagajo, da se počutite udobno, hkrati pa varčujete z energijo.

Toda sčasoma boste potrebovali novo klimatsko napravo. Ali lahko obdržite termostat NEST ali Ecobee, ko ga dobite?

Odgovor je da ... razen tistih trenutkov, ko je odgovor ne. Dovolite nam, da pojasnimo.

Če standardno klimatsko napravo zamenjate z drugo standardno klimatsko napravo, lahko obdržite svoj pametni termostat.

Standardne klimatske naprave z eno hitrostjo se dobro ujemajo z večino standardnih pametnih termostatov, kot sta NEST in Ecobee. Navsezadnje so pametni termostati namenjeni nadzoru standardnega klimatskega sistema.

Torej, ko zamenjate standardni AC z drugim standardnim AC, zamenjate podobno s podobnim. Seveda bo novi sistem učinkovitejši od vašega prejšnjega in morda bo celo drugačne znamke HVAC. Toda v bistvu gre za isto vrsto klimatske naprave.

To je nekako tako, kot ko kupite nov 13" prenosnik in prodate svoj stari 13" prenosnik na eBayu. Ker je novi prenosnik enake velikosti kot vaš stari, lahko obdržite isto torbo.

Ali bo vaša nova klimatska naprava združena s puhalom s spremenljivo hitrostjo?

Tukaj se stvari zapletejo pri termostatu NEST ali Ecobee. Vsakič, ko nadgradite na sistem s spremenljivo hitrostjo (mimogrede, kar je zelo pametna odločitev), lahko ohranitev obstoječega pametnega termostata oslabi eno največjih prednosti nove opreme:razvlaževanje.

Vidite, ena največjih prednosti ventilatorjev s spremenljivo hitrostjo je zmožnost dolgotrajnega delovanja pri nizki hitrosti in razvlaževanja zraka – tudi potem, ko sistem zadosti potrebam vašega doma po hlajenju. Tukaj v Atlanti nam dodatno razvlaževanje močno pomaga pri ohranjanju udobja v zaprtih prostorih!

Ta funkcija predstavlja težavo za vašo napravo NEST ali Ecobee. Unlike the thermostat that comes with your new variable speed furnace or air handler, NEST and Ecobee thermostats can't turn the system on to dehumidify your air. In other words, you forfeit your ability to effectively dehumidify by keeping the NEST or Ecobee.

These thermostats can lower the blower speed to dehumidify your air, but only after the system is already running. If you've already met the temperature you've set on the thermostat, they won't turn the system on to dehumidify.

At PV, we mostly install Trane equipment. The Trane ComfortLink™ 1050 or 850 thermostat that comes with your new variable speed furnace has the ability to read temperature and humidity and turn the system on when relative humidity (not just temperature!) spikes beyond your comfort threshold. Similar systems from other manufacturers also come with integrated thermostats that allow the system to perform at its fullest potential.

Spodnja črta? Sure, you can keep your NEST or Ecobee with a variable speed furnace or air handler. But it will never be as effective as a thermostat that's made to work with your new system.

Can you keep your smart thermostat when you get a communicating HVAC system?

No, you can't. Fully communicating systems only work properly with the manufacturer's approved thermostat. Otherwise, they really don't, you know... communicate.

Let's use Trane as an example. There are several Trane furnaces to choose from, but two really popular ones are the XV80 and the XC80. Both have variable speed blowers, but only the XC80 is fully communicating.

Say you get the XV80 (the non-communicating one). You can still use your NEST or Ecobee thermostat, but as we explored a moment ago, you lose the ability to turn the system on for dehumidification. It'll work, but it won't really do one of the things you presumably bought it for (dehumidification).

Now let's say you get the fully communicating XC80. This one has a variable speed blower andthe system is designed to control temperature and humidity in a very precise fashion by communicating with a Trane ComfortLink™ 1050 or 850 thermostat. You simply cannot forgo Trane's thermostat and keep your NEST. If you do, the system will not work at all. It's made to communicate only with Trane's thermostat.

So, the XC80 (communicating) will not work with your NEST or Ecobee. The XV80 (non-communicating) will, but you'll still lose the ability to begin dehumidification when the system is off (see previous section).

The verdict:Don't keep your NEST or Ecobee if you want a communicating HVAC system. It just won't work.

The thermostat that comes with variable speed systems is still really smart.

That's the thing to remember. When you "give up" your NEST or Ecobee in exchange for the thermostat that comes with your new variable speed HVAC system, you're still going to have a smart thermostat.

With the ComfortLink™ 1050 or 850 thermostat, you get pretty much all of the features your existing smart thermostat has. Plus, you know it's going to work perfectly with your variable speed equipment.

In the end, you'll be even more comfortable. And you'll probably save money thanks to the variable speed blower's built-in efficiencies.
