Installation can be tricky Verdict A remote sensor lets the Ecobee3 smart thermostat monitor the temperature in more than one room in your house. And, because my thermostat is located closer to my living room, as soon as it senses that my abode has warmed to 65 degrees, it shuts off the heat, leaving me shivering under my covers. The Ecobee3 thermostat has a clever solution to that problem: A remote wireless sensor that measures the temperature and communicates back to the base unit, telling it when it’s hot or cold enough.

This review was first updated on August 25 after we tested the updated Ecobee3 with Apple HomeKit functionality. It was later updated on Feb.

June 17, ’11 Comments [27] Posted in Reviews Sponsored By It’s amazing what you can automate around the house when you’ve got a nice, solid Wi-Fi network and a little ingenuity. That seems to be the gadget freak price point. I’ve setup wifi cameras around the house and plugged them wirelessly into the Synology DiskStation as a composite image and 24 hour DVR.

All this done with commodity parts and a VERY small amount of know-how. My buddy John Batdorf walked by one of these at Home Depot and bought it on a whim. Later that evening he was like “dude!!! What a clever idea! Not just a programmable thermostat, but one I can control from any connected device, the web or any phone iPhone, Android, etc.

This opens up a lot of interesting scenarios where you can get the house ready before you get home, where you can keep it colder and save money if you forgot to turn off the heat before you left.

Greenhouse Controls

The mini splits have the advantage that the refrigerant lines can run up the outside of the house, making them much easier to retrofit. After using the air source heat pumps for two months, I expect these mini splits will approximately halve that. The mini-splits will have an estimated payback of about 13 years, which is not great, but both they and the geothermal system have the added advantage of giving me efficient air conditioning in a home that did not previously have it.

Honeywell thermostat wiring instructions for 4 & 5 wire applications. Learn how to wire basic thermostats and digital thermostats to operate heat and cooling. If wires pass through a floor and up into a wall cavity before reaching a thermostat. Try the following.

This information is designed to help you understand the function of the thermostat to assist you when installing a new one, or replacing or up-grading an old one. The thermostat is the control device that provides a simple user interface with the internal workings of your homes climate control system.

They connect to a two-wire thermostat generally a mechanical thermostat with a mercury filled ball connected to a coiled bi-metal strip. A basic two-wire thermostat can be compared to a simple single-pole switch that you will find throughout your home, only instead of you turning the switch on and off as required, a mechanical or electronic temperature controlled mechanism is the operator of the switch.

They usually operate at 24V ac power, and the source of this control power comes from a control transformer mounted either just outside, or inside the furnace body. In this the most basic of heating systems, as the temperature of the heat exchanger rises, another contact is closed on the line voltage side of the equation, and the fan blower motor starts moving air through the heat exchanger and out through the ducting in the home.

There are four wires: Can you tell me which wires go where? That’s why I usually recommend getting an expert involved when hooking up a gas appliance, even if it’s just wiring up a fireplace thermostat. However, a homeowner with average DIY skills and the documents that came with the fireplace should be able to do the low-voltage wiring for a thermostat. If you purchased the home new with the fireplace installed, the manual may be in with the other appliance paperwork provided by the builder.

However, if you aren’t the first owner of the home and weren’t provided the booklet by the previous owner, it’s possible you may be able to go online to the fireplace manufacturer’s website and download a manual there. The manual should describe exactly how the thermostat is to be wired. This type of wiring is low voltage so as long as the wires are on the correct terminals and there aren’t any bare wires touching, the thermostat should work properly. However, if you question at all your ability to do the job properly or there isn’t a wiring description in the manual, I highly recommend calling in a fireplace contractor to do the hook up.

Video of the Day Instructions Turn off the power to your furnace by turning the switch on the side of the furnace to the “off” position. Remove the access panel on the front of the furnace and locate the control board. You will find a terminal strip where the low voltage control wiring hooks up to. Locate the “G” terminal, which controls the blower operation from the thermostat, on the board. Connect the green low voltage wire to the “G” terminal and put the access panel back on the front of the furnace.

If no green wire exists you may need to pull a new thermostat wire from the furnace to the thermostat. Remove the thermostat from the wall. It should come off by gently pulling on it.

This thermostat is designed for a system with five wires — the wire terminations are marked as follows: W – This wire comes from the relay that turns on the heating system. Y – This wire comes from the relay that turns on the cooling system. G – This wire comes from the relay that turns on the fan. The two transformers provide the power the thermostat uses to switch on the various relays.

The relays in turn switch on the power to the fan and the air conditioner or furnace.
