GRASSIN INTERVAL TIMER CENTER PIN SETTINGS
FOR THE HMI HOYME TIMER ADAPTORS
In addition to the white pins on the periphery which may be pulled outwards to override normal circuit settings, there is another pin (switch) located in the centre of the timer face as shown by the Red Arrow.
|
There are three positions for the centre pin. The normal position is in the ‘middle’. In this position the timer will operate as it should. Each white pin extended outwards on the periphery represents 15 minutes each of current control.
|

|
|
The centre pin placed in the up ‘ I ‘ position will cause the timer to act as if all the white pins were extended.
|

|
|
The centre pin in the down ‘ 0 ’ position will cause the timer to act as if there we no pins extended.
