Digital input is used to provide a signal to 
instigate an Override and switch all Pump 
relays “ON”, as determined by P*374, 377, 
380,  383,  386,  389,  392  (Assignment), 
P*302 (Override Delay) and P*303 (Min. 
Override). 
Digital input is used to provide a signal to

5 = Reset.  
(Wallmount Input 4 only) 
(Fascia Input 7 only)     
Input is used to Reset all Device Fail 
conditions.          
Alternatively the  key can be used, whilst 
the in RUN, to Reset any Device Fail. 
 
Input is used to inhibit the measurment of 
the point it is allocated too as specified by 
P*374, 377, 380, 383, 386, 389, 392 
(Assignment).

When P*373, 376, 379, 382, 385, 388, 391 = 1 (Device Fail) or 2 (Duty) 
This parameter assigns the digital input to the appropriate device relay that 
the Function, (P*373, 376, 379, 382, 385, 388, 391), is to be applied.
