CENTRAL HEATING WIRING DIAGRAM TWO PUMPS

Central heating diagram - Mike the Boilerman
People often ask me for central heating diagrams showing how the pipework circuits are arranged in a central heating system. There are almost infinite variations but there are four main types; Gravity. One-pipe. Semi-gravity. Fully-pumped. The first two are completely obsolete in domestic heating and only rarely encountered. The other two are

Heat Pump Thermostat Wiring Diagram
Heat pump thermostat wiring - A typical wire color and terminal diagram. As shown in the diagram, you will need to power up the thermostat and the 24V AC power is connected to the R and C terminals. The color of wire R is usually RED and C is BLACK. C is known as the common terminal. These two connections will ensure that there is power to the thermostat that you are operating.

Thermostat Wiring Diagrams [Wire Installation] Simple Guide
Thermostat Wiring Diagrams for Heat Pumps - Heat Pump Thermostat Wire Diagrams. Heat pumps are different than air conditioners because a heat pump uses the process of refrigeration to heat and coole an air conditioner uses the process of refrigeration to only cool, the central air conditioner will usually be paired with a gas furnace, an electric furnace, or some other method of heating.
How a Gas Furnace Works | HomeTips
Get a Local Heating Pro Fast! A gas forced-air heating system goes into action when the thermostat tells it that the room temperature has dropped below a preset comfort level. The thermostat sends a low-voltage electrical signal to a relay in the furnace, which signals a valve to open and deliver natural gas to the burners and for the blower to turn on.

This is the schematic to use with a Heat Exchanger or Primary Loop system. The pump running the heat exchanger/primary loop is called the system pumpously, it needs to run when any zone calls for heat. For (either) Primary loop pump or Heat exchanger pump connections, both neutral (white wire) and load (black wire) to the “System pump” connections at the bottom of the relay box
