1.3.2 Installation requirements
1.3.3 Connection to surrounding air
Leave sufficient space to install a blower plenum* on top of the unit in order to orient the air flow, if
possible towards the bay windows opening on the exterior.
*unit distributing air to the blowing system
1) Install the appliance on a level base, to avoid any overflows from the condensation
tray,
2) Easy access to the appliance for maintenance and connections, leave
1 meter of free space around the CAE.
3) Place nothing in front of or on the blowing and suction grates,
4) Anti-vibration studs (supplied) must be installed under the appliance,
5) For a swimming pool building with a high ceiling or visible roof frame:
- destratification of the upper layers of the room = one or several fans with PVC
blades or an air extractor with fresh air intake.
Warning! 230 V AC appliances = must be outside volume 1 (see §1.3.1),
6) Building requirements: swimming pool building = very damp room
During building make sure that:
- the materials used are compatible with a swimming pool environment,
- the walls are sufficiently waterproofed and insulated to avoid condensation forming in
the room when relative humidity reaches 60 to 70%.
Light structure buildings (verandas, shelters...): there is no risk of deterioration of the
structure, even in case of dew as they are designed to support this (even with a relative
humidity of 70%)
7) Risk of stratification:
- height of the room < 4 to 5 meters: mechanical ventilator unit or extractor,
- height of the room > 7 to 8 meters: ceiling fans with large blades,
8) Ventilation, renewal of air,
- private pools: highly recommended
- public pools: compulsory
The air can be renewed by:
- a simple mechanical ventilation unit,
- a wall or roof extractor with fresh air intakes.
This ventilation ensures the hygienic renewal of air, the removal of any chloramines
present in the air, and the elimination of excessively hot air, whilst contributing to the
dehumidification of the room.

1.4.3 Checks
In the Hygro Control comfort model (see §1.3.7.4)
check that hot air is coming out of the blower grates,
check that the appliance is draining condensation,
1.4.4 Adjusting the duct network
Set the air flow by adjusting the grate dampers (recommended speed ≈1metre/second) identically on
all the blower grates.
1.4.5 Commissioning the options
The heating options are operational from 4°C surrounding air temperature.
1.4.5.1 Extra heating
follow the procedure described in §1.4.2,
starting up Hygro Control and adjust the thermostat to between 26 and 28°C (maximum 30°C), in
general choose an air temperature 1 to 2°C higher than the pool water temperature,
check that with the “VI/VP” switch on “VI”, and no dehumidification or defrosting cycles in progress:
- the fan stops operating, after post-ventilation of 3 minutes when the reference room temperature
on the pool room thermostat is lowered,
- in the event of abnormal overheating, the appliance shuts down the heating option automatically,
by shutting off the heating elements and keeping the ventilation operational (for as long as a
heating request is active).
This safety device has two levels of triggering:
1) by “THS” safety thermostat if the T°C is > 65°C (it is automatically
reset),
2) if the temperature continues to increase, the second positive
“THSM” safety thermostat puts the appliance into safety mode.
=> reset it manually (with power off), after having checked that the
appliance air flow is correct (with the “VI/VP” switch on “VP”), that the
grates are not obstructed, that the filter is not clogged, and the fan is
not defective.
1.4.5.2 Hot water battery
Supply the battery with hot water at 45 °C minimum from the heat source (boiler, heat pump,
geothermal energy, solar heating), installation must be carried out by a qualified technician, using a
circulator (not supplied) which will be powered by terminals C-C on the electrical terminal board.
connection to a ZPCE double circuit gas boiler: connect the terminals 3-6 of the terminal board, to
terminals 3-6 of the boiler terminal board,
follow the procedure described in §1.4.2,
adjust the thermostat between to 26 and 28°C (maximum 30°C), in general set the air temperature
1 to 2°C higher than the pool water temperature,
If your pool has a cover (shutter or bubble sheet type, etc.), you can lower the room
temperature (by adjusting the thermostat to about 20°C) when it is in place and raise the
pool hall temperature before removing the cover.
Terminals 3-6 can also ensure a heat source control function (see §1.3.7.3)
Insulate the hot water battery hot water pipes between the heat source and the appliance
(for the purpose of limiting calorie loss).
if your pool has a cover (shutter or bubble sheet type, etc.), you can lower the room
temperature when it is in place (by adjusting the thermostat to about 20°C) and raise the
pool hall temperature before removing the cover.
When the “ECP 600” regulator is switched on ventilation is active for 5 minutes.
This also occurs if the appliance is powered on and the “on/off” switch of the
Hygro Control delivered with the appliance is used.

a post-ventilation runs for 3 minutes when the reference temperature is reduced on the thermostat
located in the pool hall (with the “VI/VP” switch on “VI”, without any dehumidification or defrosting
cycles in progress): check that the circulator stops.
1.4.5.3 Titanium water condenser
connect the intake and output to the filter using a by-pass, according to
the markings on the appliance (before the pool water treatment system),
see §1.3.8.2,
Adjusting the by-pass for the water condenser :
- open valve half way
- open valves and completely
plan to shunt the filter clock from the S-S terminals on the CAE electrical terminal board,
in the case of a hydraulic connection with pump that is independent of the filtering system, plan to
power this pump using the P-P terminals on the CAE terminal board (maximum power: 60W with
230V AC, otherwise relay the power supply from an extra electric contactor),
starting up:
- follow the procedure describe in §1.4.2,
- set the “TH” digital display thermostat fitted inside the electrical box:
- press “SET” to display the current reference value (factory preset at
27°C, thus the thermostat output will be activated when the pool room
temperature will rises above 29°C and deactivated if the temperature
drops below 27°C): the “out 1” LED blinks (hysteresis = 2°C),
- press or (possible range values: 25°C minimum and 45°C
maximum),
- press “SET”, or do not operate for 15 seconds, to confirm.
check that the filter pump starts when the adjustment of this digital display
thermostat is reduced to below the surrounding temperature.
check that the « VCA » indicator lights when the thermostat reference value
is lowered. By default, check that the filter pump is operational and sufficiently irrigates the water
condenser (see by-pass adjustment).
when the water condenser option is operational (VCA indicator on), check that the « EV » solenoid
valve is powered from terminals E and V (230V ac) on the appliance terminal board.
If this is not the case adjust the by-pass so that there is a sufficient flow of water in the condenser to
activate the flow controller fitted at the output of the water condenser (this safety device is connected
between terminals I and D, see the electric wiring diagram in the appendix).
Warning - low temperature: if the dehumidifier hot water battery is not supplied by a
boiler, but by an aero-thermal or a geothermal system, the heating circuit water will be at
a maximum temperature of 45-40°C. The power of the battery will then be considerably
lower (3 to 4 times less) than the nominal power given for water at 90-70°C. If the power
of the battery is lower than the heating needs of the room, plan for additional heating by
radiator, heated floor or fan convector.

N - R mains-supply 230Vac-50Hz to the ECP600 regulator
20 - 21 output from compressor supply 230 Vac -50Hz
30 - 31 230Vac-50Hz output (only used with water condenser option) and protected by the
ECP600 fuse
22 - 23 ventilator 230Vac-50Hz output
25 - 24 output for circulator hot water battery option 230Vac-50Hz or contactor coil for extra
heating
26 - 27 output alarm report 230Vac-50Hz
28 - 29 output contact “NO” (without polarity) control of heat source hot water battery option
11 – 12 - 13 Input control sensor type PTC (inlet or defrost)
4 - 5 power supply 12Vac-50Hz
7 input 6Vac-50Hz given by the hygrostat function (request active if 6Vac-50Hz
between 7 and 4)
2 input 6Vac-50Hz given by the thermostat function (request active if 6Vac-50Hz
between 2 and 4)
8 input 12Vac-50Hz fan heat fault (fault active if 0Vac-50Hz between 8 and 4, “défaut
thermique ventilateur” led lit)
9 input 12Vac-50Hz faults BP and/or HP, and/or phase order (CAE three-phase) (fault
active if 0Vac-50Hz between 9 and 4, “défaut pressostat HP ou BP” led lit)
10 input 12Vac-50Hz compressor heat fault (fault active if 0Vac-50Hz between 10 and
4, “défaut thermique compresseur” led lit)
Led lit continuously Meaning
“compresseur”
= compressor the compressor is operational (blinking = temporisation in process)
“EPROM” ECP600 regulator out of order
“défaut thermique
ventilateur”
= fan heat fault Triggering of the auxiliary contact Q1.1 on the Q1 thermal relay
“défaut pressostat
HP ou BP”
= high or low
pressure switch fault
triggering HP and/or LP switch and/or phase order relay KA4 (only on CAE
three-phase)
- HP : check that the ventilator is operational, that the air filter is clean and
the belt is tight enough,
- LP: insufficient gas, call a specialist,
- KA4: check for the presence of the 3 phases, if so, see §1.4.2.
“défaut thermique
compresseur”
= compressor heat
fault
Triggering of auxiliary contact Q2.1 on the Q2 thermal relay
“déclenchement
alarme”
= Triggering of the
alarm
- HP and/or LP switch triggered more than 3 times in one hour
- order phase relay KA4 triggered (only on CAE three-phase)

16
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

3. Maintenance
3.1 Maintenance instructions
3.1.1 Monthly checks
Check for clogging in the filter:
- wash the filter with warm soapy water,
- rinse it abundantly and dry it,
- replace it if necessary.
Check visually that the condensation is drained.
3.1.2 Quarterly checks
Check the tightness of the centrifuge fan belt: push the belt down between the two pulleys, it
should yield about 1 cm.
3.1.3 Annual checks
check that the electric cable connections, contactors and fuses are correctly tightened,
Loose cables may cause overheating of terminals,
check that each command relay, power switch and electronic protection device is operational,
check the adjustment and operation of the Hygro Control and the water condenser thermostat if
necessary clean the dust inside it using a jet of air,
clean the whole unit with a slightly damp cloth,
check the cleanliness of the condensation drainage tray and tube,
check the condition of the insulating foam on the technical compartment
check the movement of the centrifuge ventilator blades (the bearings are greased permanently and
need no maintenance),
check that the batteries are clean. If necessary clean them using a hard silk brush, a vacuum
cleaner or a jet of compressed air. Rinse using cold water under pressure taking care to avoid
splashing water on the ventilator motor.
Be aware of the following:
On the three-phase CAE, via the phase controller (KA4), any modification of the order of
phases on the distribution network or on the existing electrical installation is detected.
The appliance then goes into fault mode (“alarm triggered” led lit), see § 2.1.
The appliance must have a filter fitted when operating.
Appliance powered off and decommissioned!
A general servicing of the appliance is strongly recommended to check the proper
operation of the appliance, maintain its performance, to avoid certain faults and preserve
the building in good condition.
