Pump by Time 
 
When Ultra Wizard = 2 Pump/Differential 
When  a  relay  is  assigned  to  Pump  by  Time  the  pump  will  come  on 
(energise)  at  its  normal  “ON”  level  setpoint,  and  de-energise  at  its  OFF 
level setpoint or after a predetermined time period, whichever occurs first.  
P210, 220, 230, 240, 250 = 5 (Pump by Time) 
When  a  relay  is  being  used  for  a  pump  by  time  function,  the  second 
parameter determines the pump duty that will be used to determine the 
operating cycle.  
P211, P221, P231, P241, P251 - Relay Function, 
This  parameter  defines  which  pump duty  the  relay should  respond  to  as 
follows. 
Relay is always de-energised. 
All pumps are used to assist each other 
(run at the same time) and each pump 
has its own setpoints. (P213, 223, 233, 
243, 253 & P214, 224, 234, 244, 254). 
If a pump fails to meet the demand (due 
to malfunction, intake blockage etc.), 
then it is stopped and another pump shall 
take over. Each pump has its own 
setpoints. (P213, 223, 233, 243, 253 & 
P214, 224, 234, 244, 254). 
All pumps are used to assist each other 
(run at the same time). Each pump has 
its own setpoints, (P213, 223, 233, 243, 
253 & P214, 224, 234, 244, 254) but 
each time all pumps have stopped, the 
setpoints are sequentially rotated 
between the pumps to ensure equal 
pump use.
