Compressor activation may be enforced at the beginning of the awakening and rising phases; the duration of such
enforced activation is determined by parameter P29.
Compressor activation is subject to the safety times (parameters P26, P27 and P28)
21. SOLENOID VALVE
Only present if P71 = 0. When P71 = 0, P44 must be configured correctly.
The solenoid output is always activated together with the compressor, except for when compressor activation is
enforced, which happens at the beginning of the awakening and rising phases (the solenoid will remain disabled). The
solenoid is also used whenever the cell requires dehumidification (see paragraph 19).
22. LIGHTS
The light output (present if parameter P71 has value 1) will be switched on when you open the door and switched off
when you close the door.
23. EVAPORATOR FAN CONTROL
You can choose the fan control output from one of the relay outputs and a phase cut output. This is done by means of
parameter P45. If P45 = 0, fan control will be performed by output LOAD5. In this case, you can also establish whether is
subject to the activation of the compressor and/or the resistances or if they must always remain on. If P45 = 1, a
proportional adjustment through the phase cut will be chosen.
23.1. Relay output control (P45 = 0)
If you select the control simultaneous mode, fans will be activated at the same time as the compressor and/or
resistances, but will be switched off with a delay determined by parameter P54. During the pauses, in case of
simultaneous operation, fans will be cyclically switched on according to the value of two parameters (P55 and P56).
Example of simultaneous operation subject to the compressor.

P54 P56 P56 P55 P55
If parameters P55 e/or P56 are = zero, fans will remain off.
Pause/working time will always be reset when a cycle is started.
Opening the door will immediately switch off the fans.
