Values obtained at operation with maximum unit power input. Values obtained at standard Eurovent unit operating conditions: air 35°C, water 12/7°C. Values obtained at operation with maximum unit power input. Values given on the unit name plate. 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 156) -- User safety: this contact can be used for any customer safety loop; opening of 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 CONTROLS ■■ The Energy Management Module offers extended remote control possibilities: -- Room temperature: permits set-point reset based on the building indoor air temperature (with Carrier thermostat) -- Set point reset: ensures reset of the cooling set-point based on a 4-20 mA or 0-5 V signal -- Demand limit: permits limitation of the maximum chiller power or current based on a 0-10 V signal -- Demand limit 1 and 2: closing of these contacts limits the maximum chiller power or current to two predefined values.
