In this mode both pumps can work in different modes, switching between
pumps is made by NMTC module.
- Alternating mode [factory set] - One pump works, while the other one is
in standby. Pumps automatically switch on and in to standby every 24
hours, or when an error occurs on one pump.
- Reserve mode - One pump is always on, while the other one is in standby.
If an error occurs, then the reserve pump will turn on. This mode is turned
on, so that you put the pump that you want to be in standby, to standby by
holding key for 5 seconds.
- Combined mode – both pumps work with the same head in constant
pressure mode. This mode is used when there is a need for a flow that a
single pump can't reach. When the limit of the first pump is reached, then
the other one will turn on supply the needed power to reach that flow.
This mode is activated, so that you set the same constant pressure head
on both pumps.
