both relays. The higher limit activates the relay and the lower

Both commands can also be entered without entering a trigger point
value. The command withour parameters gives the current set value.

x = 1 or 2 (number of the relay)
yyy = trigger point (CO
Example of setting the higher trigger limit of the relay 1:
>MF_R1_HIGH 1200
MF_R1_HIGH=1200.0000
>
Save the settings:
MAIN_SAVE F<cr>
Give the lower trigger limit:
MF_Rx_LOW yyy<cr>
where:
x= 1 or 2 (number of the relay)
yyy = trigger point (CO
Example of setting the lower trigger limit of the relay 1:
>MF_R1_Low 900
