Over the past 6 months or so I’ve noticed a drop in highway mpg from to approx After checking out a number of forum discussions particularly bimmerfest and some European d forums , I thought possibly my thermostat was malfunctioning, with resultant low engine temps. So a low engine temperature for the diesels may cause poor mpg, burn out of glow plugs, and DPF malfunction. This link on bimmerfest gives an excellent overview of the issue. As said by lpcapital in post 5: There are plenty of reports of aged thermostats that keep the engine in the low 70s when cruising on freeways.
How to Install a Two Wire Thermostat
These high capacity thermostats provide for the greatest number of heaters to be controlled with a single thermostat. The TH is also the slimmest of all our thermostat models.

It adjusts the temperature up and down according to your schedule, so you use energy when you need it and conserve energy when you’re away. When you install your Honeywell thermostat, it’s important to understand its wiring. Learning to wire a Honeywell thermostat is easy when you determine the color-coded system. Step 1 Turn the air conditioning and heating unit off by flipping the appropriate circuit breaker.
Test the unit to make sure it’s off by turning your existing thermostat to the “On” position and seeing if it turns on. Wiring a Honeywell thermostat when the circuit breaker is on could cause you to blow the transformer that powers the HVAC unit. The thermostat R terminal operates both the heating and cooling units, and contains an internal jumper wire.
Basically, your red wire on a Honeywell thermostat is the hot wire that runs from the transformer. Step 3 Run the green wire to the thermostat G terminal. The green wire controls the relay that operates the blower, and it controls the fan. Step 4 Control your air conditioning when you connect the yellow wire. It connects to the thermostat Y terminal.
Hooking up new thermostat to new furnace
Long day and its dark, cold and I’m really tired. But, I am gonna go back to the air handler to see if I can find a fuse. If I can, I’ll see if its blown and replace it.
Types of Thermostat Wire. There are a variety of thermostat wire types. The main difference setting each apart is the number of colored wires. HVAC systems with more functions need more wires to communicate to and from the thermostat.

Thermostat and coolant temperature sensor removal and replacement – mk4 VW and Audi Feb 22, Thermostat and coolant temperature sensor removal and replacement – mk4 VW and Audi mk4 VW Jetta, Golf, New Beetle thermostat and coolant temperature sensor removal and replacement difficulty: The thermostat is a bimetal element which expands and contracts based on temperature. When it opens, it lets coolant into the radiator where it cools down and returns to the engine. This controls the temperature of the engine.
While the turbo on your Volkswagen TDI is oil cooled, I avoid using stop leak products because they can gum up and clog the heater core you won’t get cabin heat or turbo water coolant lines. If you are experiencing coolant temperature malfunction without engine overheating or other symptoms, it is likely that the coolant temperature sensor is the problem.

I think it was here! I’ll keep looking for it. Keep in mind I am NOT an electrician but am pretty handy. It spoke of using a thermostat powered with a 9 or 12 volt transformer to trip a volt AC relay. The relay in turn would power the fan or heater or another major appliance you wanted to run. Basically you have a low voltage transformer cell phone charger or whatever run the thermostat and send the signal to an appropriate relay.
This relay in turns “trips” when it receives the low voltage signal from the thermostat and allows the volt load that is connected to it to proceed to the appliance. The trick here is using a relay that is normally open or closed depending on what you want to run. With a thermostat, it is normally open circuit prevents current flow and which allows current to flow when it is perturbed. A normal thermostat is made for a 9 to 12 volt load. The thing would arc and spark on you so don’t try it.

These thermostats, whichever type of thermostat or thermostats you have, require little maintenance. Often, I find that the only thing people know about their AC and Heating systems is how to turn the thermostat on and off. And change the temperature setting. The purpose of this site is to help people go beyond the thermostat. To learn more about their system as a whole. And not just a dial on the wall that adjusts the temperature when they are not comfortable.
This collection of strange things wired together are the components of the thermostat. Upper left is the Arduino stack with the Arduino topped by an ethernet shield and a prototype board holding a power supply and control relays.
Super Thermostat I have two heat pumps to heat and cool my house. The house layout is such that there is no path from one part of the house to another for a big old air duct and two of them offer redundancy in case of failure. I have really nice programmable thermostats on the systems that can shut them off during the peak period but there are still a few things that would be nice to have. Ability for each of them to know when the other one is on to prevent both of them from coming on at the same time, or restrict each thermostat to a specific period of time so they don’t overlap each other.
Be able to adjust both of them from the same spot so you don’t have to run back and forth. Be able to tell if either of them are on and what they are doing when wondering what is eating up the power. Keep visitors from playing with the temperature when they think they’re getting too hot or cold. Sounds like a job for a couple of Web enabled thermostats doesn’t it? Enter another Arduino, this time a thermostat. This collection of strange things wired together are the components of the thermostat.

Below we will describe to you how to hook up a digital thermostat, hook up a programmable thermostat, or hook up any type for that matter. Whether the old thermostat is bad or not if you simply want to replace your old one and hook up a new one the first thing you need to take into consideration is to select the right replacement thermostat. To select the correct replacement you need to know what kind of HVAC equipment you have in your home or where you want to hook up the new thermostat.
There are numerous types of air conditioner and heating combinations so in this article, we will cover a basic gas furnace and air conditioner split system HVAC system.

“Hydrofarm’s Jump Start Heat Mat Thermostat controls the temperature of heat mats by providing constant optimum temperature for plants, seedlings and cuttings.
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. The company that did the original installation would be the best option, but if you don’t have that information, just about any fireplace contractor should be able to wire the thermostat.
