A81: Function E1 

With this parameter function of the ext. input E1 can be set. With A81=0 the E1 is not evaluated. 
With A81=1 the controller is switched to the standby mode. With A81=2 or A81=3 setpoint S1 is 
switched to setpoint S1’ when input E1 is closed. With A81=3 the status of E1 is indicated by LED3 
in the display.  
 

A82: Function „key 5“ (Standby) 
A83: Function „key 3“ 

The following functions are available: 
 

0: the respective key has no function 

 

1: the controller is switched to standby mode 

 

2: the key is linked with the function of parameter P1 

 

3: a relay (indicated with parameter A90-92) can be switched on or off directly with the key. 

 

    In standby mode the key is locked and the corresponding relay switched off. After  

 

    restarting the corresponding relay remains switched off 

 

4: like 3, but the relay is switched despite of

 

the standby mode. 

 

A90: Output connection relay K1 
A91: Output connection relay K2 
A92: Output connection relay K3 

Depending on existing hardware there may not be all output relays. This parameter assigns the 
respective relay to the internal controller outputs, to key 3 or 5, to the alarm contact or the buzzer.
