Additional setpoint modes
Proportional (Setpoint 2 only) The setpoint will dose in proportion to the time that setpoint 1 was on. e.g. If setpoint is energised for 10 minutes and the proportion is set to 50% then setpoint 2 will start dosing for 5 minutes immediately after setpoint 1 has de-energised. Accumulation (Setpoint 2 only) The setpoint will dose for the set dose time after the accumulation active time of setpoint 1 has been reached.
