Heat Pump Sequence of Operation – HVAC Technical
Heat Pump Sequence of Operation - Every electrical-mechanical piece of equipment has a sequence of operation. While some manufacturers of heat pumps vary slightly with their heat pump sequence of operation the overall sequence of operation for a heat pump is the same for most manufacturers. So unless you have a special type of heat pump (they are out there – the Acadia heat pump is designed for extreme cold weather temperatures up North like Canada) the sequence of operation for your heating equipment should be very similar to what is described here. This is the basic operation of a heat pump like you will find in conventional heat pumps.

Day Tank for a Diesel Generator | Critical Facilities - This is a photo of a generator day tank for a diesel generator. The tank has floats inside that keep the fuel level automatically topped off in the tank so when the generator starts there is a fuel supply ready to go. As the generator consumes fuel the pump activates and resupplies the tank to keep the generator fueled and running.
