HTI DS170 Inverter • Inverter high temperature air/water heat pump with DHW tank 70°C

The HTI high temperature heat pump with a DS170 DHW tank is an environmentally friendly device that uses the natural refrigerant R290 (propane) to heat water up to 70°C. The indoor module consists of a DHW tank of 170 liters and a built-in hydraulic module. The unit guarantees good operation down to -20°C outside temperature. The HTI monoblock is a heating only appliance with an inverter compressor; The unit maintains its high COP values even at negative outside temperatures. The DS170 consists of a monobloc outdoor unit and an indoor module with a buffer tank of 50 liters. Its compactness is its great asset and makes it applicable in most places.

Brand

  • Auer - Intuis

Application

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

Composition

Outdoor: Monoblock heatpump type HTI70 6-8-11-14 kW with supplied:
  • Communication cable of 10 m long, between HTI/Pilote (3 core and already connected to HTI) (do not place along the power supply cables)
  • Flexible pipes (Durite) of 1 m long => rest of the hydraulic circuit in fixed insulated pipe to indoor module (diameter according the distance between these two, see table at the bottom of this page)
  • Ball valve with built-in filter for placement on the return connection.
  • Pressure relief valve (2,5 bar) to be installed at the hydraulic output of the heatpump.

Indoor module Pilote DS 170 D:
  • Primairy circulation pump between the HTI heatpump and this indoor module
  • Built-in pump for circulation of central heating water through underfloor heating, radiators or fan coil units
  • Hydraulic disconnection between primary and secondary circuit
  • Enamelled tank for domestic hot water of 170 liters with built-in heating coil
  • 3-way valve for automatic switchover between DHW and CH water
  • Cast iron back-up resistance 3 kW
  • Pressure sensor
  • Electronic controller
  • Water pressure sensor
  • Expansion vessel 8L (dimensioned for hydraulic piping between indoor and outdoor unit)
  • Vent valve
  • Replaceable magnesium anode built into this tank
  • Only for models DS170 11 or 14: included buffertank 25 L (to be placed in return line)

Refrigerant

  • Ecological and natural refrigerant Propane (R290) with a GWP value of only 3

Installation

  • The secondary water pump is selected by the installer depending on the consumer network.
  • The startup of the installation is always with a technician of CAIROX BELGIUM.
  • Safety group should be placed on the cold water supply pipe - connect to drain pipe.
  • The addition of an anti-corrosion agent or a glycol/anti-corrosion mixture is mandatory.

Accessories

  • Room thermostat, type TH HRC70
  • Low water temperature regulation, type Thorix
  • Clean existing heating systems first.
  • Commissioning (STRONGLY RECOMMENDED), type XSTARTUPJ quote on request

Applicable outdoor units

  • HTI 6-8-11-14 kW
