Illustration 104: The Jockey Pump Function
11.22.2.2 (ID 1675) Jockey Start Level
Location in the menu: P3.21.2.2
Use this parameter to set the level of the PID feedback signal at which the jockey pump starts when the main pump is in the sleep
state. The jockey pump starts when PID Sleep is active and the PID feedback signal goes below the level set in this parameter.
This parameter is used only if P3.21.2.1 = 2 PID sleep (level).
11.22.2.3 (ID 1676) Jockey Stop Level
Location in the menu: P3.21.2.3
Use this parameter to set the level of the PID feedback signal at which the jockey pump stops when the main pump is in the sleep
state.
The jockey pump stops when PID Sleep is active and the PID feedback signal goes above the level set in this parameter, or when the
PID controller wakes up from sleep mode.
This parameter is used only if P3.21.2.1 = 2 PID sleep (level).
11.22.3 Priming Pump
A priming pump is a smaller pump that primes the inlet of the main pump to prevent suction of air.
The priming pump function controls a priming pump with a digital output signal. It is possible to set a delay to start the priming
pump before the main pump starts. The priming pump operates continuously while the main pump operates. If the main pump
goes into sleep mode, the priming pump also stops for that time. When waking up from sleep mode, the main pump, and the pri-
ming pump start simultaneously.
