I needed to deport the thermostat of my old gas furnace, I saw the thermostat at casto, telling me it was fine but it was too good to be true. OR after looking at the different products on the market, and without wishing to invest in a solution too expensive and without a technician, comments from Amazon I decided to buy it. after reading the very simple instructions, I've realized that the installation is simple. I unplugged the old thermostat and put in place the relay box (small white box relay) to plug into the 220V and the contact to the boiler at terminals 2 and 3 of the relay. as I had to deport the thermosat I wall-mounted and connected the thermostat on the usb cable supplied with the unit with 220v adapter. it is also possible to connect the thermostat to the relay box, care must be connected to the terminal block to the right 12v, 220v especially not! the assets of the thermostat are numerous: - Hyper design and very simple to use: just turn the dial to the left or right and then click to select. - The setup wizard is very simple - The connection with the iPhone app is very easy, it is automatically detected on the wireless network (it is necessary that the smartphone is well on wifi). - You can control the remote, the application is in French.
short I see no fault, now I think very seriously change my smoke alarm nest in the model which also enables to Carbon monoxide detector, and prevent if bp on the iphone.
I said that not encounter problems with the installation, you must have some electrical knowledge. if you do not know what it is a dry contact, or if you are not sure that your boiler is compatible, find and properly install the housing relay by a pro!
