c4: Time-delay between the ON routines of the compressors/time-delay of the capacity-controlled
routine
It allows to set the minimum time-interval between the ON routines of the two compressors so as to reduce inrush
consumption. In a capacity-controlled compressor, this parameter indicates the time-delay before the actuation of the
capacity-controlled routine. During this phase the LED relative to the compressor blinks.
c5: Time-delay before the OFF routines of the 2 Compr. / Time-delay before the capacity-controlled
routine
It allows to set the minimum time-interval between the two compressors OFF routines. In a capacity-control-led
compressor this parameter indicates the time-delay before stopping the capacity-controlled routine.
c6: Delay at start-up
This parameter allows to set a time-delay at the compressors start-up so as to balance current absorption and to protect
the compressor/s from repeated start-ups when there is some interruption in the power supply.
c7: Delay in switching ON compressor after switching ON the pump/inlet fan (AIR-AIR)
Both in the Cooling and Heating operating mode, with the pump actuated upon request of the controller (parameter
H5=2), if the compressors activation is required, the controller will first actuate the pump and then the compressors. If the
pump/inlet fan is always on (H5=1), it will start only when you start the unit (when you select Cooling/ Heating) and the
time-delay will never be enabled.
