When MLH<MLL,there is a delay of 10*(MLL-MLH) seconds on lp switch. Eventual pumpdown restart is over MLH+1 bar. Fixed time 120 s and manual reset. In H425V3, starting from revision 03, when MU1 and MU3 are 5.0 and b4A and b6A are oFF, use 5NTC controller for compressors without oil pump; connect HP probe on AN-6 and LP on AN-7. Caution! Selection by manual override forces compressor to run whatever the high and low pressure; no safety is left except hardware ones. In slave mode the output is used for partialization. In kriwan mode output is off for reset during stand-by. Caution! The external override drives the compressors ignoring high and low pressure; no safety is left except hardware ones. It is recommended to close this contact passing through both contacts of a low pressure and high pressure switch like a kp15. The closed contact is interpreted as "load" while the open contact is neutral. The delays dF4 through dF6 are respected. After the delay elapsed, the override forces a load. Automatic reset. When speed regulation is off the fan is operated on-off. Caution! Speed regulation can cause fan fault or electronic board fault. Low and average minimum speed can increase the risk. Passing from stand-by to on and at power on, there is a 5 second delay spent in a virtual stand-by. In H425V3, starting from revision 02, when PO3 is 4, OUT-3 drives the subcooler liquid solenoid; AN-1 input is the subcooler suction temperature; Mut is the wanted overheating, where 8.0 ◦ C means 8.0 ◦ C; maximum overheating is fixed at 99.0 ◦ C; minimum overheating is fixed at 6.0 ◦ C; n4H is the refrigerant type, where 0.1 bar means R404A; n4L is the cycle period, where 0.8 bar means 8 s; H4H is the initial on-time, where 0.5 bar means 5 s; H4L is the adaptation speed, where 0.8 bar means 8. To turn off the subcooler solenoid, set PO3 to 5. The subcooler is enabled just when all of the available motorcompressors are on. The minus sign on display ("-") signals that output is going to start after a delay.
