kA eff: efficiency value: rms for English version
Instantaneous start-up current (locked rotor current in star connection of the compressor).
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.
