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.
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.
