Amana-Goodman B1256559 Heat Sequencer

The Amana-Goodman B1256559 Heat Sequencer is a control part intended for residential and light commercial HVAC systems improvement. It operates by systematically alternating the turn on/turn off of one or more heat pumps or air handlers to provide equal heating across the building. This eliminates ‘short cycling’ – rapid on/off cycling which is detrimental to equipment and decreases efficiency. The sequencer controls the operation of several units at once to maintain the required temperature and to reduce power consumption. There are most useful in multi zone systems where distinct zones such as rooms or areas need different amounts of heat. The sequencer also prevents formation of hot or cold spots and ensures that all the connected HVAC equipment are run efficiently.
