Led lit continuously  Meaning 

“défaut hors 

température” 

= temperature range 

fault 

-

  temperature < than 10°C or > than 40°C (compressor stopped),  

-

  restart sensor is out of order.  

-

  In all cases, if the ventilator is active before the triggering of this fault, it is 

maintained for 3 minutes before stopping. 

-

  If the returns to within its operating range:  

-

  there is a 30 seconds delay before the fault is cleared, 

-

  there is a 3 minute delay before restarting the compressor and the fan (if a 

dehumidification request is still active) 

“cycle de dégivrage” 

= defrosting cycle 

-

  cooling circuit temperature < than -5°C or > than 40°C,  

-

  a defrosting cycle is in progress (temperature is >-5°C). The compressor is 

stopped and ventilation is maintained, 

-

  the defrosting sensor is out of order. 

The defrosting cycle stops when the temperature of the sensor goes over 
2.2°C. If the sensor is out of range (<-5°C or >40°C) during the active 
defrosting cycle, this LED remains on for 3 minutes with the ventilation 
operating, before it stops.  
In all cases, if the ventilator is active before the triggering of this fault, 
ventilation is maintained for 3 minutes before stopping. 
If the sensor returns within its operating range:  

-

 there is a delay of 30 seconds before the fault is cleared, 

-

 there is a 3 minute delay before the compressor and fan restart (if a 

dehumidification request is still active) 

Others 

Description 

“VI/VP switch”

“intermittent ventilation” (standard setting)  
or “permanent ventilation” (to permanently circulate the pool hall air) 
Using VI, a post-ventilation is active for 3 minutes.  
The ventilation is active when:  

-  dehumidification is triggered,  
-  a defrosting cycle is started, 
-  pool hall air heating is triggered, 
- 

active for at least 5 minutes in one hour without any of these 

triggers.

On VP, the compressor starts after a delay of 3 minutes. 

“Connecteur module 

de prog.”  

= programming 

module connector 

ECP 600 programming connector or implementation of a diagnosis module 
by the technical support department

ECP 600 250Vac T=10A 6,3x32 fuse 

2.2 Troubleshooting procedures 

Checks to make before any operation:  

-  correct electrical supply (voltage and cable size) 
- all cables are correctly connected 
- Hygro Control operational 
-  appliance has triggered dehumidification but not heating
