P210, 220, 230, 240, 250, 260 - Relay Type 
This parameter defines what type each relay should be, see the table below 
for available options: 
Relay is not in use or programmed and the LED will 
always be off. 
Relay is programmed as an alarm relay, which will de-
energise ON, and energise OFF.  This will ensure an 
alarm is raised if the power fails to the unit. 
Relay is programmed as a pump relay, which will 
energise ON, and de-energise OFF. 
Relay is programmed as a control relay, which will 
energise ON, and de-energise OFF. 
Relay is programmed as a miscellaneous relay, which will 
energise ON, and de-energise OFF. 
Relay is programmed as a pump relay, which will 
energise at its ON level setpoint, and de-energise at its 
OFF level setpoint or after a predetermined time period, 
whichever occurs first.
