9. WAtER PUMP MANAGEMENt
the heat pump can control two pumps. an internal pump is provided with the unit. a second external pump not
provided by airwell can be connected.
9.1. INtERNAL PUMP
the parameter P01 is used to configure the pump
²
P01 = 0, the pump will run continuously even in off mode.
the only exception is the presence of a waterflow alarm.
²
P01 = 1, the pump will run continuously except in off mode.
the pump will stop in the case of a waterflow alarm.
the pump will start in the case of an antifreeze alarm.
²
P01 = 2, the pump will run when there is a heating demand according to room conditions.
the pump will stop in the case of a waterflow alarm
the pump will start in the case of an antifreeze alarm.
9.1.1. PoSt PUMPING
the pump will always stop 2 minutes after the compressor or heat sources switches off.
9.1.2. ANtI SEIZE
the pump will run for a short time periodically to prevent the impeller from seizing
the parameters P02 and P03 control the anti seize cycle.
²
P02 is the interval in hours between the starts. if no anti seize cycles are required then this value
should be 0.
²
P03 is the value in seconds that the pump will remain on for each cycle.
