Their applicat-ion range is the same as that of the standard units, but permitsoperation at condenser leaving water temperatures up to 63°C.The PRO-DIALOG control offers all the advantages of thestandard units, plus control of the condenser leaving watertemperature.The main modifications are:- Use of 30GX compressors- Modification of electrical components to operate withcompressors for high condensing temperatures.- Modification of heat exchangers to meet pressure coderequirements (if necessary).Option 150These units are designed for traditional applications for water-cooled units, but for higher condender leaving watertemperatures than 45°C.Like the standard units they are equipped with condenserentering and leaving water sensors, installed on the piping.It is possible to control the machine at the condenser wateroutlet, requiring a factory configuration change and the use ofa heating/cooling inlet reversing device.Option 150AThese units are designed for water-to-water heat pumps.They are factory configured as heat pumps (heating/coolingcontrol as a function of the remote reversing device). Thecondenser incorporates thermal insulation that is identical tothat of the evaporator.Technical informationAll information is identical to that of the standard 30HXCunits, except for the following paragraphs.SelectionThere are no nominal conditions for this unit type. Theselection is made using the current electronic catalogue.DimensionsThese are identical to those of the standard 30HXC units. Theonly difference is in the diameter of the incoming field wiringconnection, described in the chapter “Recommended selection”.Refer to the dimensional drawings for these units, beforeproceeding with the wiring.CompressorSee 30GX compressor table.Options and accessoriesAll options available for the standard 30HXC units are compa-tible, except:Option 5, brine unit Special unitOption 25, soft start, 30HXC 200-375 units Not availableAttention:If units have two different operating modes - one with highcondensing temperature and the other with low condensingtemperature - and the transition is made with the unit inoperation, the temperature must not vary by more than 3 Kper minute. In cases where this is not possible, it is recom-mended to go through a unit start/stop switch (remote start/stop available for standard units).
