Master–Slave operation
In a Master–Slave configuration, a number of slave heat pumps are controlled by a
master heat pump’s controller. The heat pumps are started and stopped one at a time,
each after a start or stop delay. Once the start delay has elapsed, the next heat pump
in the starting order starts. The rest of the heat pumps will run at a lower capacity
to prevent a spike in the overall capacity. Correspondingly, once the stop delay has
elapsed, one of the heat pumps will be switched off, and the rest will run at a higher
capacity to prevent a sharp fall in the overall capacity.
