  • Page 6: Introduction

    Lync AEGIS 2: INTRODUCTION 2. INTRODUCTION Aegis is a highly efficient, commercial heat pump solution that uses electricity and natural refrigerant-grade CO2 to produce domestic hot water up to 185°F all year round. Using electricity and the superior qualities of R744, a natural refrigerant-grade CO2, the Aegis heat pump water heaters are one of the cleanest, most efficient and environmentally friendly ways to heat domestic water.

  • Page 7: Sequence Of Operation

    Lync AEGIS 2: INTRODUCTION 2.3. Sequence Of Operation The hot water storage tanks used in this heating system must be equipped with the two provided temperature sensors, or other sensors meeting requirements for a NTC 10k temperature sensor. The BT2 sensor (hot side probe) is located in the top of the last storage tank in the series, near the supply outlet.

  • Page 8: Version With Cool Recovery (Air Source Unit Only)

    Lync AEGIS 2: INTRODUCTION To limit the possible discomfort that can be generated by excessive heat dissipation, or excessive and rapid spillage of water from the top of the tanks, you can use the probe BT2 to operate a "comfort" function. In this case, even if the temperature BT1 is higher than the value of "Set point unit OFF", the unit operate when the BT2 is lower than a value of "Set point...
