Remark |
1 | Defrost is not performed twice in case safety switches of mc or evaporator are not ok. |
2 | The period of each cycle includes on-time + off-time, that is the overall duration of the cycle. |
3 | Following defrost cycles will be aligned to the end of forced one. |
4 | Add 100 to FPt parameter to enable the outer defrost drive on INP-4. The defrost is initiated by INP-4 closure; after defrost and until INP-4 is closed, the instrument does not leave the dripping mode, to coordinate with eventual other instruments. |
5 | In case of hot gas defrost, both IA2 and IA3 must reach Ftt. |
6 | When MLH<MLL,there is a delay of 10*(MLL-MLH) seconds on lp switch. Eventual pumpdown restart is over MLH+1 bar. |
7 | Fixed time 120 s and manual reset. |
8 | When activated, pump down mode forces compressor continuous run, switched off only by low pressure limit. |
9 | Forced refrigeration is disabled when room temperature is under LFL, forced heating is disabled over LFH. |
10 | When speed regulation is off the fan is operated on-off. |
11 | Caution! Speed regulation can cause fan fault or electronic board fault. Low and average minimum speed can increase the risk. |
12 | During the first 10 seconds of speed regulation, the n1L is replaced by (n1H+n1L)/2. |
13 | No action if the light is switched on from inside the room. |
14 | When off, the refrigeration solenoid is steadily on during cooling, as long as overheating is higher then vtL or b3A is off. |
15 | Caution! Low overheating causes liquid return and compressor damage. |
16 | Caution! Short duty cycle reduces valve life. |
17 | Caution! Low overheating causes liquid return and compressor damage. |
18 | Caution! High adaptation speed causes swing in the suction line and damage to the compressor. |
19 | In H422V9, starting from revision 14, when b1A is on, b4A is off, and b4C is non-zero, use AN-4 reading with set at 0.0 °C + b4C to concur for low temperature alarm and to stop cooling. |
20 | The low temperature differential is fixed, and alarm status stops at 0.2 °C above the set point. |
21 | The high temperature differential is fixed, and alarm status stops at 0.2 °C under the set point. |
22 | Passing from stand-by to on and at power on, there is a 5 second delay spent in a virtual stand-by. |
23 | The minus sign on display ("-") signals that output is going to start after a delay. |
