* Instantaneous start-up current ** This can vary as a function of the short-circuit current / maximum current ratio of the system transformer . *** Values obtained at operation with maximum unit power input **** Values obtained at operation with maximum unit power input . Values given on the unit name plate . † When the machines are equipped with two power supplies , circuit 1 is dedicated for supplying refrigerant circuit A , and circuit 2 is dedicated for supplying refrigerant circuit B . †† Values obtained at the normalized Eurovent operating point of the unit : air 35 ° C , water 12 / 7 ° C .
Note : Motor and fan electrical data if the unit operates at Eurovent conditions ( motor ambient temperature 50 ° C ): 1.9 A , start-up current : 8.4 A , power input : 760 W .
Options
Remote management ( EMM option )
■ ■ The Energy Management Module ( EMM ) offers extended remote control possibilities :
--
Room temperature : Permits set-point reset based on the building indoor air temperature ( if Carrier thermostat are installed )
--
Set-point reset : Ensures reset of the cooling set-point based on a 4-20 mA or 0-10 V signal
--
Demand limit : Permits limitation of the maximum chiller capacity based on 0-10 V signal
--
Demand limit 1 and 2 : Closing of these contacts limits the maximum chiller capacity to two predefined values .
--
User safety : This contact can be used for any customer safety loop ; opening the contact generates a specific alarm .
--
Ice storage end : When ice storage has finished , this input permits return to the second set-point ( unoccupied mode ).
--
Time schedule override : Closing of this contact cancels the time schedule effects
--
Out of service : This signal indicates that the chiller is completely out of service .
--
Chiller capacity : This analogue output ( 0-10 V ) gives an immediate indication of the chiller capacity .
--
Alert indication : This volt-free contact indicates the necessity to carry out a maintenance operation or the presence of a minor fault .
--
Compressors running status : Set of outputs ( as many as the compressors number ) indicating which compressors are running .
