LI TE – Indoor

Description

The LI range of internal air source heat pumps has seven models with heating outputs ranging from 11–40 kW. The LITES units are designed for indoor installation on an external wall or in a corner, making them ideal for installations where it is not practical to install an external unit.

Features and benefits:

  • Configurable for corner or wall installation using air ducts for the air intake and the air outlet (supplied by installer). Dimplex rain guards are available as an accessory.
  • Two compressors for output regulation when operating at partial load (LI20–40TES only).
  • Capable of flow temperatures up to 60°C with high COP due to an evaporator optimized for heating operation and energy-efficient reverse cycle defrost. Reduced noise due to sound-optimized axial fan and vibration-isolated compressor.
  • Supplied with integrated WPM2007 plus controller heat pump manager which can be wired as a remote control using the optional MSPGD wall mounting set. Compatible with BMS system or Ethernet network with an additional accessory.
  • Integrated flow and return sensor, dirt trap and flow rate sensor. External NTC-2 sensor included in the scope of supply.
