■■ Auto-adaptive control
-- Control algorithm prevents excessive compressor
cycling and permits reduction of the water quantity in
the hydronic circuit (Carrier patent)
■■ Exceptional endurance tests
-- Corrosion resistance tests in salt mist in the laboratory
-- Accelerated ageing test on components that are
submitted to continuous operation: compressor piping,
fan supports
-- Transport simulation test in the laboratory on a vibrating
table.
-- Packaging crash test to ensure that the units are
adequately protected against accidental shocks.
■■ All units are tested at various stages on the production
line for circuit leakage, electrical compliance, water and
refrigerant pressures.
-- End-of-line test of all unit operating parameters.
-- Third-party testing and certification - all performances
are certified by Eurovent and unit safety is certified by
DEKRA.
Corrosion-resistant casing
Controls
User interfaces
■■ The AquaSnap can use the following user interfaces:
-- Dry contacts
-- The AquaSnap Junior remote controller (option)
Pro-Dialog+ control
Pro-Dialog+ combines intelligence with operating simplicity.
The control constantly monitors all machine parameters and
precisely manages the operation of compressors, expansion
devices, fans and of the water heat exchanger water pump for
optimum energy efficiency.
■■ Energy management
-- Seven-day internal time schedule clock: permits unit
on/off control and operation at a second set point
-- Set point reset based on the outside air temperature
or the return water temperature or on the water heat
exchanger delta T
-- Master/slave control of two units operating in parallel
with operating time equalisation and automatic
change-over in case of a unit fault.
-- Change-over based on the outside air temperature
■■ Integrated features
-- Night mode: capacity and fan speed limitation for
reduced noise level
