Introduction
Refrigerant circuit
The new generation of CW-AR water source heat pumps is the fruit of our
considerable product experience and our awareness of the market, all combined
with a technology based on the energy efficiency of machines, in order to
provide on the market units with the highest performance in terms of COP.
The refrigerant circuit comprises a rotary type hermetic compressor, a cycle
reversal valve, a water/refrigerant heat exchanger, a liquid receiver, and a
finned coil. The refrigerant circuit also comprises an HP pressure switch
with automatic reset function (range 29-24 bar) and an LP pressure switch
with an automatic reset function (range 1.4-2.4 bar). Two direct external
access Schrader valves (HP & LP) are available for pressure tapping on the
refrigerant circuit.
Operating range
To enable a much wider operating range and installation using a water source
in an application with a dry cooler, the standard CW-AR units are designed to
operate in a water source temperature range between 13 and 45 °C.
The water/refrigerant heat exchanger is of the brazed stainless steel plate
type, for increased efficiency. The anti-freeze safety of the heat exchanger
is provided by a water pipe sensor located on the water outlet of the unit
monitored by the electronic board. Maximum service pressure water side
(27.5 bar) and refrigerant side (30 bar). The heat exchangers are particularly
well adapted to the operation of reversible heat pumps with high thermal
transfer rates for a low water flow rate.
Cabinet
The cabinet is made of galvanised sheet steel painted RAL 9010.
To facilitate access to the main components, front removable panel provides
access to the compressor, the fan and the electrical box.
The air/refrigerant coil is made of aluminium fins which are mechanically
crimped onto copper tubes. The geometry of the coil and of the fin profile
have been carefully designed to provide maximum efficiency in the operation
of the units.
The condensate drain pan has anti-corrosion treatment consisting of ovenbaked epoxy paint.
The inside of the cabinet, on the fan compartment side, is coated with 15 mm
thick closed cell polyurethane foam thermal-acoustic insulation, classified M1.
The cycle reversal valve is designed to be normally energised in heating mode.
This logic enables the heat pump to continue to operate in cooling mode if
this valve fails.
On the compressor compartment side, the thermal-acoustic insulation is of
20 mm thick Isofeutre type with heavy mass.
The liquid receiver enables the charge of HFC 407C refrigerant to be optimised,
in order to maintain a high COP value.
Versions
Ventilation section
The CW-AR range is available in several versions :
The fan compartment contains the fan-motor assembly, the air/refrigerant coil
and the condensate drain pan. The ventilation section is completely isolated
from compressor compartment by a thermally and acoustically insulated
partition wall.
 CW-AR CAR : standard version with cabinet,
 CW-AR CARB : low height version with cabinet,
 CW-AR NU : standard version without cabinet,
Wide removable panels provide access to the various internal components.
The condensate drain pan has an anti-corrosion treatment.
 CW-AR NUB : low height version without cabinet.
Each version can be supplied, as standard, with feet or with front air intake
RF (optional).
All the units are equipped with a 3 speed direct-drive fan motor with ipsothermal
protection against overheating during operation. The motor ipsothermal
protection fault is displayed in the form of a coded signal on the LED of the
RCL remote control.
Filtration
All units are equipped as standard with a disposable G2 filter.
The 3 fan speeds can be controlled either manually or automatically by the
electronic management board of the unit.
Access to the filter can be realized by the front or the bottom (according to the
version CW-AR RF or CW-AR with feet).
EC optional motor available on request.

Control Features
STORM 2 electronic board
RCL user remote control
All CW-AR water source heat pumps are, in their standard version, equipped
with a STORM 2 electronic board which manages their operation and their
safety devices.
STORM 2 electronic board
Master/slaves control : the standard version of the STORM 2 electronic board
enables operation in master/slaves regulation mode for up to 10 water source
heat pumps using a single RCL user remote control.
This configuration enables the installer to save on the purchase and wiring of
equipment such as auxiliary relays and multi-wire cables between the various
water source heat pumps. Only a bus cable with 2 twisted pairs is necessary
between the master and slave units.
RCL user remote control
When a request for operation in cooling mode is received, the fan-motor
assembly is started up immediately and the compressor does not start until
after an effective time delay of 180 seconds. The RCL remote control enables
operation in cooling-only mode or in automatic cooling/heating mode with, at a
given temperature set-point used as a switch-over point, a neutral switch-over
range of +/-3 °C from cooling to heating mode. In cooling mode, the fan runs
permanently and the 3 speed ventilation can be implemented in automatic or
manual mode : HS, MS, or LS.
An RCL user remote control is supplied as standard in the electrical control
box of the units.
It enables individually controlled operation as stand-alone regulation.
The RCL remote control is ergonomically designed and discreet. It comprises
a digital display and essential functions such as :
On/Off,
When a request for operation in heating mode is received, the fan-motor
startup is controlled by the electronic board and the temperature of the ICT
sensor; the reversal valve is activated before the compressor and the latter
does not start until after an effective time delay of 180 seconds. The RCL
remote control enables operation in heating-only mode or in automatic heating/
cooling mode with, at a given temperature set-point used as a switch-over
point, a neutral switch-over range of +/-3 °C from heating to cooling mode.
In heating mode, the fan can operate either cyclically (the fan stops when the
set temperature is reached) or permanently and the 3 speed ventilation can be
implemented in automatic or manual mode: HS, MS, or LS.
Selection of operating mode,
Room temperature display,
Fan speed selection,
Temperature set-point adjustment.
A keypad locking function is also available.
The RCL user remote control comprises a Display LED which shows the
operating status of the water source heat pump (Lit : On - Unlit : Off), and it
also enables an operational fault to be identified by flashing a specific code.
Measurement of the room air temperature : the STORM 2 card electronic
regulation enables the selection of a room temperature measurement mode
which uses an ambient temperature sensor (RCT) in the RCL remote control,
or a return temperature sensor (RAT) located directly on the water source
heat pump.
Anti-short cycle : after each compressor shut-down, a time delay of 180
seconds is introduced by the electronic board. This time delay constitutes an
anti-short cycle device and therefore helps to protect the compressor.
5
Control Features (continued)
Variable sequential start-up function : when the system is first energised, or
after a power cut, or after opening the "CLK" contact, a random time delay of 0
to 30 seconds is introduced by the electronic board to prevent the water source
heat pumps from all starting up simultaneously, thus avoiding a power surge.
µBMS mini-supervision station
Emergency shut-down / stand-by / night setback : the electronic board has
two "CLK" terminals which shut the unit down immediately.
32 water source heat pumps in 15 zones from a single point, in addition to
This centralised control unit is proposed as an option, and can be connected to
the STORM 2 electronic board as a supervision station to monitor and manage
the local RCL remote controls.
By incorporating a zone thermostat in series, the "CLK" contact can also be used
as a night setback and the water source heat pump will start up again as soon
as the ambient temperature drops below the set point of the setback thermostat.
The µBMS mini-supervision station enables the zones to be programmed
with global control for all zones, or with individual control of each zone
Anti-freeze safety function : this is provided by two temperature sensors. In
cooling mode an "ICT" temperature sensor located in the finned coil protects
the water source heat pump against accidental freezing.
with programming of the operating time ranges over a 7 day period, with
In heating mode, the safety function is provided by an "LWT" minimum water
outlet temperature sensor. The anti-freeze fault read by the temperature sensor
is displayed by a coded signal on the LED of the RCL remote control.
It also provides the possibility of having different set-points in different zones.
management of the heating, cooling and night setback modes.
µBMS mini-supervision station
High temperature safety function : the "ICT & LWT" temperature sensors
check that the condensation temperature at the finned coil and the water
temperature at the outlet of the water/refrigerant heat exchanger do not exceed
the authorised limits.
The manual reset HP pressure switch completes the high temperature safety
function. The high temperature safety fault read by the ICT and LWT sensors
and the HP pressure switch cut-off is displayed by a coded signal on the LED
of the RCL remote control.
Fault reports : the electronic regulation carried out by the STORM 2 board
uses coded signals to remotely report four different possible machine faults
on the display LED of the RCL remote control :
- HP pressure switch triggering,
- Water temperature fault in low limit,
- Water temperature fault in high limit,
- Anti-freeze protection.
The STORM 2 electronic board also enables the general machine fault to be
sent to a remote fault relay via a dry contact.
Motorized valve : The STORM 2 electronic board has a 230 volt output for an
(optional) motorized valve controlled by the operation of the compressor, in
order to enable the flow-rate of the hydraulic pump(s) to be regulated according
to the manometric pressure in the water source.
