The single time delay cycle starts at switching on
of the iRTH relay power supply

b
The load is energized during an adjustable time T1
and then de-energized during an adjustable time T2.
This cycle is reproduced until de-energizing of the
iRTL relay power supply

Depending on the choice, the iRTMF generates
time delay cycles for the iRTA, iRTB, iRTC or iRTH
relays
