Mini termostati
Circuito elettronico semplice, ma ben funzionante e di facile regolazione (reperibili facilmente sul web le istruzioni). Vengono spediti 2 circuiti e due sonde ntc. Io ne ho usato uno per costruire un mini impianto di raffreddamento per un dvr (al fine di prolungarne la vita). Finora funziona perfettamente.Ottimo rapporto qualità-prezzo.

Works as expected
Bought these (only in fact needed one) to control solar powered ventilation fans in my greenhouse. Can be configured to operate in cooling (on when set temperature exceeded) or heating (on when below set temperature). There's a couple of degrees hysteresis so it won't oscillate too much. The LEDs show the current temperature and it seems fairly accurate. The temperature probe supplied has a reasonably long lead and is potted into a metal cap, making it waterproof (the board itself will of course need protecting in a box).Configuration is simple, albeit a bit tricky to figure at the start I found. It essentially comes down to up and down buttons to set the trigger temperature. The settings are non-volatile so survive power loss.Was a bit concerned about the current drain given I'm using it in a solar/battery environment. However, even though it has pretty bright LEDs they have minimal drain on my small Li-Ion pack (not enough to discharge it over night anyway).

Good product. As specified
Works exactly as specified. I use it to control an electronic solenoid connected to a tap which turns on a mister in my greenhouse if it gets too hot. Easy to program too

Produit défectueux
Les températures mesurées sont inexactes. Les deux thermostats que j'ai reçus ont le même problème : même dans un environnement à température constante et contrôlée, les températures varient en continu de +/- 3°/4°C en quelques secondes. J'ai demandé le retour des produits achetés.
