TECHNICAL SPECIFICATIONS OPERATING LIMITS ENVIRONMENT This equipment is designed EXCLUSIVELY for INDOOR installation. In general, sheltered locations such as garages, roof space, etc, do not provide sufficient protection against extreme temperatures and/or humidity and may be harmful to the unit’s performance, reliability and service life. TEMPERATURE LIMITS Cooling Heating... -
Page 9: Électric Spécifications
ÉLECTRIC SPÉCIFICATIONS ELECTRICAL POWER SUPPLY A variance of ±10% is acceptable in relation to the operating voltage marked on the appliance’s Maker’s Plate. Operating voltages: ² 230V / 1 ph / 50 Hz (207 Volts minimum; 253 Volts maximum.) Comments: the stated voltages represent the accepted range. However, certain components may be subject to premature wear on appliances operating continuously, for extensive periods, on abnormally low or high voltages. -
Page 10: Ducting And Noise Level Reduction
DUCTING AND NOISE LEVEL REDUCTION Water circuit heat pumps are usually installed in conjunction with an air blowing duct. A return air duct may also be required. All ductwork shall be compliant with best air conditioning engineering practices. The air blowing duct system normally consists of a flexible connector mounted on the unit, a bridging section to link to the size of the main duct, a short section of straight duct, an elbow without a damper and a main duct with spurs equipped with distribution grilles as illustrated in the drawing below. -

Page 12: Modifying The Air Blowing Direction
MODIFYING THE AIR BLOWING DIRECTION The unit sizes 07 to 12 can be supplied configured for either frontal air blowing, known as "IN LINE", or for side air blowing, known as "REAR". It is also possible to modify the air-blowing configuration on site. To achieve this: 1 - Remove the top panel 2 - Remove the fan motor access panel release a small length of motor cable. -
Page 13: Ventilation
VENTILATION An outdoor air intake (new air) may be required for ventilation. The blown air temperature must be controlled in order to avoid the temperature of the mixture of outdoor air and return air at the heat pump inlet exceeding the appliance’s operating limits. -

Page 15: Hydraulic Connections
HYDRAULIC CONNECTIONS RECOMMENDATIONS FOR HYDRAULIC CONNECTIONS 1. It is recommended that all units are connected to a water supply and return pipe system of the Tickelman Loop type. The Tickelman Loop system is self-balancing and thus only requires manual balancing if a large number of units with different flow and pressure loss characteristics are connected to a single hydraulic loop. - Page 16 Never connect a unit to the water supply and return lines without completely cleaning and flushing out the hydraulic loop beforehand. After performing these operations, the units must be connected, with all valves completely open, ready for the system to be filled with water. COMMENT: In order to limit clogging the plate heat exchanger and to optimise unit operation, it is advisable to equip the system with a sieve filter (Ø...

Page 17: Recommendations For Cleaning And Flushing Out The System
RECOMMENDATIONS FOR CLEANING AND FLUSHING OUT THE SYSTEM 1. Before commissioning an appliance for the first time, the water loop must be cleaned and rinsed out to remove any dirt and manufacturing debris.

RCL AND µBMS CONTROL MODULES WIRING Unscrew the lower screw on the RCL control. Separate the RCL control from its support bracket with the help of a flat bladed screwdriver Lower screw Checking the support bracket : Ensure that the wall surface is completely flat at the point where you wish to install the RCL control, as it is important that the support bracket is not twisted on installation, because any bending could lead to the control not clipping together properly and result in operating difficulties. - Page 21 Set the DIP switches marked J1 and J2 in accordance with your configuration nd the modes that are accessible.

Page 22: Μbms
µBMS The µBMS control module must be connected in accordance with the diagram below. Use screened twisted pair telephone wire with a section of between 0.12 and 0.5 mm²for wiring the control modules. Refer to the following chapter for detail of the appliances’ addressing. The use of the µBMS recall command is not compatible with the modbus communication. -

Page 24: Return Air Temperature Measurement
RETURN AIR TEMPERATURE MEASUREMENT As the default factory setting, the jumpers are configured so that return air temperature measurement is performed via a sensor located on the RCL control module. If the RCL control module is not sited in the air-conditioned premises or is sited at a distance for various reasons, we recommend the use of the Return sensor (RT) located on the appliance itself. -
Page 25: Rcl Only
RCL ONLY 10 appliances can be connected to a single RCL remote control module. The maximum distance between the RCL and the first unit is 30 metres. The maximum distance between the RCL and the furthest unit is 100 metres. 100 m maximum between the 100m MAXI RCL and the last appliance. -
Page 26: Modbus
MODBUS The MODBUS supervision can be connected to a maximum of 123 appliances. ² The maximum distance between the RCL and the first unit is 30 metres. ² The maximum distance between the RCL and the furthest unit is 100 metres. The use of the µBMS recall command is not compatible with the modbus communication. -
Page 27: Addressing Procedure
ADDRESSING PROCEDURE BEFORE STARTING THE ADDRESSING PROCEDURE YOU MUST MAKE SURE THAT THE UNIT IS SWITCHED OFF AND THAT THERE IS NO POSSIBILITY OF IT STARTING UP UNEXPECTEDLY. Each machine connected to a µBMS central supervision unit or a MODBUS system must receive an address according to the procedure below. -
Page 28: Μbms Supervision Module
µBMS SUPERVISION MODULE The number of addresses is limited to 15 with a µBMS central supervision unit. The addressing will be performed using only DIP switches 1, 2, 3 and 4. The addressing carried out according to the table below means that all the units located in the same area will receive the same settings. -
Page 29: Motorised Water Valve
MOTORISED WATER VALVE The W/V output on the STORM 2 can be used for a 230 V connection to supply a motorised water valve (the valve motor capacity must not exceed 250 Watts). When this valve is installed on the system, it limits main circulation pump energy consumption as well as limiting the overall pressure losses in the hydraulic circuit. -
Page 30: Demand For Heating
Reminder: if one of these factors is situated at its minimum or maximum level, the other should be situated at a normal level in order to ensure the unit’s correct and normal operation. 2. Ensure that the thermostat is connected properly and set the set temperature below the ambient temperature of the zone to be cooled. -
Page 31: Maintenance And Servicing
MAINTENANCE AND SERVICING 1. Normal maintenance of the appliances is generally limited to replacing filters. 2. The filters must be changed at regular intervals. The frequency is dependent on the specific application conditions. Certain installations, for example in hotels where there large amounts of fluff due to the frequent bedding changes and the presence of fitted carpets, require more frequent filter changes. -
Page 32: Insufficient Cooling Or Heating Production
INSUFFICIENT COOLING OR HEATING PRODUCTION 1. Check that the thermostat is properly located in the zone to be heated or cooled and that it is not near to a source of cold or heat that may influence the reading. 2. Check the proper operation of the Return Air Temperature (RT) sensor, located on the fin exchanger. 3. -
