HTI PREMIUM+ • Inverter high temperature heat pump 70°C

The HTI air/water heat pump uses heat from nature and converts it into usable hot water. The construction of the unit makes it possible to heat water up to 70°C at negative outside temperatures without using a resistance. The unit guarantees good operation down to -20°C outside temperature. The natural refrigerant R290 (propane) has a GWP value of 3 and is therefore hundreds of times better than alternative refrigerants. The HTI is a single heating unit that uses a scroll compressor to ensure a good operation in part load and a low power consumption. Due to the special construction of the unit, the unit will have to defrost less often and the defrost cycle will be completed as efficiently as possible. The unit maintains its high COP values even at negative outside temperatures.

Brand

  • Auer - Intuis

Application

  • Production of domestic hot water
  • Floor heating
  • Fan coils
  • Radiators

  • Renovation of houses

Composition

Monoblock outdoor unit HTI70 6-8-11-14 kW including:

  • Communication bus cable 10 m long HTI/ Pilote (3-wired and already connected to the HTI) (do not connect in parallel with the power cable).
  • Flexible hose (Durite) 1 m long => rest in an insulated rigid pipe towards the indoor module (diameter depending on the distance between the two, see table below).
  • Ball valve with integrated filter to be mounted on the return connection.
  • Overpressure valve 2.5 bar to be mounted on the flow connection.


Indoor module Pilote PREMIUM+:

  • 1x primary + 1x secondary pump
  • Buffer tank/ hydraulic decoupling bottle 38 liters with air purge and drain valve
  • Extra hydraulic connection for bivalent operation with boiler
  • Adjustable backup resistance 0-6 kW
  • Pressure sensor
  • Flow meter
  • Electronic regulation
  • USB stick (included with manual)
  • Outdoor sensor for weather dependent control

Installation

  • When combining production of DHW with central heating water, an extra pump and a DHW S HRC70 sensor must be provided.
  • The addition of an anti-corrosion agent or a glycol/anti-corrosion mixture is mandatory.

Accessories

  • Room thermostat TH HRC70
  • Domestic hot water sensor DHW S HRC70
  • Additional secondary pump HRC PK Premium+
  • Regulation on 2nd circuit with lower water temperature THORIX
  • Clean existing heating systems first.
  • Startup is chargeable (MANDATORY), type XSTARTUPJ with quotation on demand and with startup report according to Auer standards

Applicable boiler

  • Warm water tank 300 liters, type SANI+ 300 R-AQUA
  • Warm water tank 500 liters, type SANI+ 500 R-AQUA

Notes

A: HTI70
B: Bivalent with existing central heating boiler possible
C: DHW-tank optional
D: 2nd circuit DHW or CH
