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.
The AquaSnap can use the following user interfaces: - Dry contacts - The AquaSnap Junior remote controller (option) 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
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.
