Refrigeration units and water-to-air heat pumps
AVANT electronic control
Casing made of galvanised steel panels with baked polyester paint coating in RAL 7035. This electronic module with microprocessor, comprising a control board and a TCO user terminal, carries out the following functions: Selection of the operating mode: cooling, heating, automatic, ventilation and dehumidification. Modification of the setpoint. Continuous monitoring of operating parameters. Display of values measured by the sensors. Compressor time delays. Control of the supply air temperature. Monitoring of the compressor discharge temperature via a sensor. Control of the water circulating pump Hourly and weekly time schedule. Diagnostic of faults and general alarms. Number of starts and runtime counters for the unit components. Optional functions: Humidity control. Free cooling heat management. Control of auxiliary electrical heaters. Control of an auxiliary hot water coil. Detection of fouled filters. Fire protection. Connection to a centralised management system (CMS) for supervision. This control can include a pGD1 terminal for maintenance as an option, which facilitates initial programming of the unit, modification of operating parameters and a description of alarms which are produced. Copper tube coils with copper blades, or aluminium blades with protective polyurethane coating. Options for control and other controls. Auxiliary electrical heaters. Auxiliary hot water coils (except for model 25). Fouled filter differential pressure switch. Condensation pressure control. Start-up kit for single-phase models. Rubber anti-vibration mounts.
Stainless steel brazed plate heat exchanger.
Direct drive centrifugal fan (models 25 to 40) or belt-driven fan (models 50 to 155). Air-cooled coil with copper tubing and aluminium blades. Washable air filter. Condensate drain pan.
Hermetic reciprocating compressor on anti-vibration mounts with silencer on compressor discharge and acoustic insulation. Thermal cut-out. Four-way cycle reversing valve, crankcase heater and liquid tank (IXH series).
High and low-pressure switches. Water circulation control (IXH series). Main door switch (except on model 25). Thermal-magnetic protection for the compressor power supply line. Thermal-magnetic protection for the fan motor assembly power supply line (models 50 and 155). Fan heat protection. Automatic control circuit switch. Integrated antifreeze protection in the control (IXH series).
Complete electrical cabinet, fully wired. Main earth connection. Fan motor (models 50 to 155) and compressor switch.
