P3.21.2.2 JOCKEY START LEVEL (ID 1675)
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.
NOTE!
This parameter is used only if P3.21.2.1 = 2 PID sleep (level).
P3.21.2.3 JOCKEY STOP LEVEL (ID 1676)
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.
