Over-cooling Though the most common problem is overheating, the opposite may also happen and will create long-term problems. Any good Fresh Water Cooling System should have excess cooling capacity. This compensates for the inevitable decrease in cooling capacity that results from the normal buildup of dirt on the heat transfer surfaces. In order to make sure that such a system, when new and clean, does not over-cool, a thermostat is used to control the flow of coolant to the heat exchanger. Over-cooling can only result from the thermostat not functioning properly. Thermostat NOT functioning properly.

Step 1 – Turn Off the Electricity First turn off the mains electricity. This step will ensure that none of the wires you touch are carrying any voltage. Step 2 – Identify Your Type of Thermostat Before you proceed, you must know what kind of thermostat you have. If you are not sure, check the number of wires that stick out of the panel.
A heat pump, as part of a central heating and cooling system, uses the outside air to both heat a home in winter and cool it in summer. HEAT PUMP OVERVIEW Technically, a heat pump is a mechanical-compression cycle refrigeration system that can be reversed to either heat or cool a controlled space.
Initial thoughts… I like it a whole lot, but there are definitely a few things to keep in mind with this technology. More about this later… first pictures of the install! A Closer View of the Compressor Unit It seemed like a pretty straightforward install, with a single heating contractor spending maybe 2 hours on the inside, and 4 hours on the outside, and the two electricians 2 hours wiring the new V line to the panel, pulling a long feed across the house, and installing a disconnect next to the heat pump.
Let me explain… After installing the heat pump we needed to adjust the thermostats down for two of the radiant zones to take advantage of the cheaper heating price of the heat pump. Probably most people would allow for a greater temperature difference between their heat pump and primary heat source thermostats to maximize savings. Do I need to cycle my radiant to keep it from freezing, or is the insulated slab enough within the building envelope to keep that from happening?
Last night I experimented by placing a small plug-in fan inside my bedroom and blew the colder air out into my family room where the heat pump is installed. It seemed to make a dramatic difference at the temperature inside my bedroom. That way, if the temperature inside my bedroom is colder than the family room the fan will kick on and exchange the air until the temperatures are similar, at which point the fan will turn off.
A Couple More Considerations Both the inside and outside units of the heat pump make some noise. The low hum of the outdoor unit makes is completely livable mounted on the outside of my family room, but most likely would have made it hard to sleep if mounted on the outside of my bedroom. The inside unit can be anything from a low swish, to a moderate level blowing of air depending on what level the fan is set.
Most often I leave the fan set on level 2 which provides a noise level I can live with and moves enough air to heat the majority of the house.

Unlike regular central air systems the unit is indoors, which is a big reason why geothermal systems have a year lifespan, almost double that of conventional systems. The geothermal heat pump is about the size of a small refrigerator and is extremely quiet, in fact its so quiet that it can be difficult to tell if the unit is running or not.
The indoor unit is attached to the outdoor ground loop. Once water, which has circulating through the loop, enters the heat pump the unit removes the heat and transfers it throughout your home in the winter.
Apr 05, · The new thermostat manual refers to B as “reversing valve operating in heat mode single stage heat pumps only” and I do not have a heat pump. Inside the furnace, the blue wire is connected to a"C" on the : Resolved.
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.
The best you can do with the included remote controller is set them to turn on and off once each during a given 24 hour period, and you have to manually set this up every day to use them that way. Since he told me he would have to figure out how to do the install from the documentation, and I had seen him struggling with the translated-from-Japanese when he was trying to figure out what was wrong with one of the units when it was first installed. It turns out two of the wires were reversed.

The loop in the floor would be filled with water and a type of antifreeze I forget the name of the stuff in case the system needs to be shut down during the winter months leon said: You can purchase reflective plastic foundation rolls to use as an underlayment from Agricultural Supplies, Fabric Structures, Equine Buildings, Grain Storage, Livestock Buildings from FarmTek and save a lot of heat from going into the ground and being lost.
Unfamiliar with this type of heat.
ICM Controls SC – SimpleComfort PRO Series Programmable Thermostat – 1 Heat/1 Cool/1 Heat Pump – ICM’s SimpleComfort PRO thermostats feature innovation and technology that delivers measurable value, simplifies installation and increases profitability.
In heating mode, heat pumps are essentially an air conditioner running in reverse. Latent heat energy in outdoor winter air is extracted by refrigerant circulating through the outside coil. The heat is concentrated as the refrigerant passes through the compressor and then conveyed inside to a coil installed in the indoor air handler. As the refrigerant rapidly depressurizes in the coil, it releases its load of concentrated heat energy. Below that level, most units incorporate electric resistance coils mounted in the air handler that automatically energize to supply the supplemental heat necessary to keep the house toasty.
Electric supplemental heating required below 35 degrees is substantially more expensive than either heat from a heat pump or gas-fired heating. If outdoor temperatures frequently drop below the minimum, homeowners may discover that savings gained by utilizing the efficient heat pump are negated by the high operating costs of frequent reliance on supplemental electric heat. Dual Is Better Than One A dual-fuel furnace takes on the problem with a hybrid approach that combines a heat pump and a backup gas-fired heater.
As long as outdoor temperatures remain above the balance point, the heat pump handles the job of keeping the house warm with typical heat pump energy-efficiency and low operating costs. Meanwhile, an outside sensor and thermostat continuously monitor the outdoor air temperature.

Posted on May 29, by Braeden Christian Replacing thermostat by yourself without a Denver HVAC technician may be beauteous harrowing if you do not hook up the wiring correctly. Inside of the thermostat there are various terminals which will have to hook up with the right wires. R means Red, the Colorado heating repairman will have to have red wires going to this terminal. This power comes from the transformer.
If your a/c includes a heat pump, then order thermostat kit number or This kit includes a white digital thermostat, relay box, freeze control sensor wire, power wire & mounting screws.
Bk Needless to say, there really needs to be a better labeling or coloring system. In fact, thermostats should really go towards an IP system and use an Ethernet cable. Let me say that Nest support was awesome. I could talk with a clearly spoken woman who worked in Oklahoma and took the time to understand, address, research and resolve my issue promptly. She sent me an email to reply back with photos of the original thermostat wiring and my current wiring on the Nest which helped things along.
Their number is Here is how I now have my Nest 3rd Generation thermostat wired and working: Turns on the heat pump compressor G: When on, reverses the heat pump valve to go from heat to cool in the summer Rc: Turns on electric heat coils C: Turns on another set of standby electric coils for emergency heat After I got the corrected wiring, I went into the pro settings and switched it from dual-fuel to single-fuel.
At that point in time the Heat Pump Balance option showed up.
