Remark |
1 | Defrost is not performed twice in case safety switches of mc or evaporator are not ok. |
2 | The evaporator fans are restarted after FdF delay and before FdE delay, as soon as the defrost temperature reaches FtP. |
3 | The period of each cycle includes on-time + off-time, that is the overall duration of the cycle. |
4 | Eventually disabled by the parameter FPr. |
5 | Following defrost cycles will be aligned to the end of forced one. |
6 | 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. |
7 | In H422V9, starting from revision 09, when FPt or FPF is 6, Ftt and FtF set the HP dew temperature that stops heat pump defrost. |
8 | In case of hot gas defrost, both IA2 and IA3 must reach Ftt. |
9 | Fixed time 120 s and manual reset. |
10 | When activated, a clever pump down algorithm coordinates the solenoid, the evaporator and the mc. There is no concurrent run of mc and electric defrost or heating. |
11 | Forced refrigeration is disabled when room temperature is under LFL, forced heating is disabled over LFH. |
12 | When speed regulation is off the fan is operated on-off. |
13 | Caution! Speed regulation can cause fan fault or electronic board fault. Low and average minimum speed can increase the risk. |
14 | During the first 10 seconds of speed regulation, the n1L is replaced by (n1H+n1L)/2. |
15 | No action if the light is switched on from inside the room. |
16 | When off, the refrigeration solenoid is steadily on during cooling, without any safety. Use turbo mode for better control. |
17 | The address of the central unit who is broadcasting pressure (usually 1). Use 0 for previous application H425V1 with no origin specification. |
18 | Caution! Low overheating causes liquid return and compressor damage. |
19 | Overheating over the maximum forces valve anticipated opening. |
20 | Overheating under the minimum delays valve opening. |
21 | Caution! Short duty cycle reduces valve life. |
22 | Caution! Low overheating causes liquid return and compressor damage. |
23 | Caution! High adaptation speed causes swing in the suction line and damage to the compressor. |
24 | In turbo mode, the liquid refrigerant solenoid opens over vtt overheating, and closes at vtL. In H422V9, starting from revision 34, to enable turbo during heat pump, add 10 for on-mode and 20 for auto-mode. |
25 | Positive values mean temperature descent. |
26 | 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. |
27 | The low temperature differential is fixed, and alarm status stops at 0.2 °C above the set point. |
28 | The high temperature differential is fixed, and alarm status stops at 0.2 °C under the set point. |
29 | Passing from stand-by to on and at power on, there is a 5 second delay spent in a virtual stand-by. |
30 | In case a crankcase heater is installed, a long delay is advised. Press Esc to skip compressor delay. |
31 | The minus sign on display ("-") signals that output is going to start after a delay. |
32 | The use of this parameter is restricted to ReFreeX authorized personnel; further detail is available on demand. This parameter is not implemented on every instrument. The value and the action of this parameter are local to each slave. If you are unsure, during action relative to this parameter, press B1 at any moment. Three underscores, three zero digits, and three empty-characters are considered trivial password values; any other combination of three alphanumeric characters is a non-trivial password. If a non-trivial password value is set, then entering the menu, the label PAS is shown. Press B6, then introduce the password, confirm by B6, and press B4. If the introduced value does not match the saved password, then the label PAS is shown again, and the operation may be retried for a maximum of other two times. In case of unlocking failure, the label bAd is shown. To exit, press B4 twice or B1 once. To remove the password, set EPA to value 000 . To set or to change the password, if you know the authorization code, set EPA to a new non-trivial value, and exit the menu. The label rEP is shown. Press B6, then reintroduce the same password, confirm by B6, and press B4. The label AUt is shown. Press B6, then introduce the authorization code, confirm by B6, and press B4. |
