  • Page 5: Introduction

    Lync AEGIS Controller 1: INTRODUCTION 1. INTRODUCTION The Aegis heat pump water heater comes equipped standard with an Eliwell PLC controller, Carel touchscreen interface, and an available LAN interface. The Aegis heat pump software can be fully parameterized and configured. Certain configurations depend on plant engineering choices and must not be changed in any way except by expert personnel.

  • Page 6: Operating Principle

    Lync AEGIS Controller 1: INTRODUCTION Figure 1-3: Water Source Heat Pump(W/W) 1.2. Operating Principle The unit control software is responsible for regulating the outlet water temperature from the appliance. The parameter displayed as " ST01 Set Hot Water" is user adjustable.

    Lync AEGIS Controller 1: INTRODUCTION NOTE: Speed regulation of the domestic hot water pump is independent of the internal pump. 1.6. Superheat Set Limit For inlet water temperature > 30 °C (>86°F) the superheating is managed by 3-way bypass valve in combination to specific software improvements.

  • Page 10: Anti-Legionella

    Lync AEGIS Controller 1: INTRODUCTION The high pressure set point is not fixed, but instead is calculated based on inlet water temperature, outlet water temperature, and evaporation temperature. The pressure is managed by the thermostatic valve. The setpoint value is limited between a minimum and a maximum fixed value. Within these limit values is also active a compensation curve based on the evaporator temperature that keeps the compressor within the required operating envelope.

  • Page 11: Phase 1

    Lync AEGIS Controller 1: INTRODUCTION The anti-Legionella cycle consists of two phases - in phase 1 the compressor is active, and the pump modulates as per standard thermoregulation (on “ALG10 Unit anti-Legionella set”), while in phase 2 the compressor is inactive, and the pump forced to default speed (on “ALG11 Unit phase 2 pump set”):...
