Remote controlXTRA CONNECT 2 is equipped as standard with an RS485 serial port that allows many remote management, supervision and diagnostics possibilities over a communication bus.
Several contacts are available as standard to control POWERCIAT remotely over a wired connection:
n automatic operation control: the machine shuts off when the contact opens.
n setpoint 1/setpoint 2: a second cooling setpoint is activated when this contact closes (e.g. energy storage mode)
n setpoint adjustable via 4-20 mA signal: this input adjusts the COOLING setpoint
n compressor load shedding: the closing of these contacts turns off the corresponding compressor(s) to lower the machine’s electricity or refrigerant consumption
n water pump 1 and 2 control: these outputs control the contactors of one or two water pumps
n fault signalling: this contact indicates that a major fault has occurred and caused one or more refrigerating circuits to turn off
Energy meter (optional)n Energy meter fitted in the machine’s electrical cabinet measures the following:
- voltage across each phase
- total input current
- total input power
- total electricity consumption
n The meter also enables the machine’s maximum electricity consumption to be kept below a limit that can be set in the controller. This limitation can be activated:
- at all times
- by an on/off input
- over a Modbus BMS network
Capacity controln Continuous capacity control
- between 25% and 100% (1800X (HPS) to 4800X HPS models)
- between 17% and 100% (4850X HPS to 6600X HPS models)
Frame and housingn Frame made of coated panels (RAL 7035 and RAL 7024).
n Housing made of panels with enamel finish (RAL 7035 and RAL 7024).

LXH - LXC series
The “ALL INTEGRATED” solution
The PLUG and COOL solution offered by POWERCIAT LXH - LXCThe hydraulic equipment integrates all the components necessary for the correct operation of the installation :
- 950 litres insulated buffer tank (LXH only)
- 80 litres expansion vessel
- Large choice of single or twin pumps for high head pressure (1)
- Manometers with shut off valves
- Pressure relief valves (calibrated at 4 bars)
- Drain circuit
- Manual and automatic air vent
- Control of the assembly
- Antifreeze protection (optional)
The hydraulic equipment, whose components have been selected in an optimal way, mounted and tested in factory, makes the installation of units easy and economical.
The preparation/commissioning times and the space required on site are therefore perfectly optimised.
(1) Our pumps are designed for operation on a closed water loop (low NPSH). For other applications, consult us (open water circuit, important intake height, etc).

n Recovery example on desuperheater
Note : heat recovery performances for : è machine running at full load, chilled water = +12/+7°C and outside air = +35°C°Cè hot water temperature on recovery = +55/+60°C
n Principle and precautions of hydraulic connectionTo start and run the machine under good conditions, the circuit must be as short as possible, and the water flow of the desuperheater must start slowly to normal operating condition, with a water flow equal to 10% of its standard value, and must be calculated for a hot water inlet temperature of +50°C.Thus, it is recommended to have a hydraulic diagram making it possible to obtain very quickly a hot water at the inlet of the desuperheater (3-way valve + controller + temperature sensor on the exchanger water inlet)The controller set point must be adjusted to +50°C minimum.Note: pay attention to the selection of the expansion tank, because the recovery water circuit can reach the temperature of 115°C in the event of circulator stop or non hot water consumption.

n Diagram of the refrigerant circuitThe following refrigeration diagram describes an example of a CIAT unit, with desuperheater (on each refrigerant circuit).The heat recovery is possible only if the machine is running.For the same cooling or heating capacity, the desuperheater system allows a free heating of hot water with a reduction of the total input power of the machine.

LX - LXH - LXC totaL reCovery Heat eXCHangerBy installing a water-cooled condenser directly upstream of the air-cooled condenser on each circuit, all the heat generated by the unit can be recovered in order to produce free, additional hot water at medium temperature.This option is not available for the LXH-LXC hydraulic versions of models 1800 X to 2500 HPS.
Refrigeration circuit diagramThe refrigeration diagram below shows a unit equipped with a water-cooled heat-recovery condenser on each refrigeration circuit. For heat recovery to be possible, the unit must be operating.For the same cooling capacity, the heat-recovery condenser provides a source of free hot water and lowers the unit’s electrical power consumption.
Example of recovery with a condenser
Note: recovery performance based on:è unit under full load and nominal chilled water conditions of +12°C/+7°C èrecovery hot water temperatures of +40°C/+45°C
Hydraulic connections: configuration and precautionsIn order to ensure that the unit can start and operate under the proper conditions, the recovery condenser water loop must be as short as possible. The gradual warm-up must, in all cases, always ensure a water inlet temperature of at least +20°C.We therefore recommend a hydraulic circuit configuration that makes it possible to achieve hot water at this temperature in the heat-recovery condenser (three-way valve + thermostat + sensor on heat-recovery condenser water inlet). The thermostat setpoint must be at least +20°C.Comment: special attention should be paid when selecting the expansion vessel, as the temperature of the recovery water circuit can reach 120°C if the accelerator pump is turned off or if no hot water is consumed.

Check also minimum and maximum temperature differences according to minimum and maximum flow (see curves «Hydraulic characteristics»).
minimUm chilleD wateR piping volUmesXtra Connect microprocessor fitted on POWERCIAT units allows a very flexible adjustement of the operation in comparison with the drift of parameters, especially for hydraulic installation with low water volume.
The auto adaptive control of the units and modulating capacity control on each compressor avoid the use of anti-short cycle function and the installation of buffer tank.
Minimum chilled water piping volumes calculation for the following conditions :
- chilled water temperature : 12°C / 7°C
- condenser air inlet temperature : 35°CThe calculation of the minimum water volume is given for EUROVENT rated conditions, in cooling mode only.
This value is applicable for most air conditioning applications (assembly with fan coil units)
Note: for installations running with a low volume of water (assembly with air handling unit) or for industrial processes, the buffer tank is a required component.
For heat pump applications, we recommend the use of a buffer tank to ensure a stable temperature is maintained during the defrosting cycles.
