AERMEC HMI Reversible Air/Water Heat Pump Installation Guide

AERMEC HMI Reversible Air/Water Heat Pump Installation Guide

DESCRIPTION

Reversible outdoor heat pump for air-conditioning systems where, in addition to cooling rooms, high-temperature hot water is required for heating or for the production of domestic hot water. For the production of DHW it is mandatory to combine it with the domestic hot water storage tank DHWT300S.

HMI is designed to meet the needs of both the new constructions market and the renovation market, replacing or working alongside conventional boilers.

It can be combined with low-temperature emission systems such as floor heating or fan coils, and also with more traditional radiators, and comes supplied with the main hydraulic components needed, thereby facilitating the final installation.

FEATURES

Operating limits

Working at full load up to -25 °C outside air temperature in winter, and up to 48 °C in summer. Maximum temperature of water produced in heating mode 60 °C.

• Refrigerant circuit with economizer.
• DC brushless axial flow fans designed for aerodynamic optimisation, reducing the noise level whilst at the same time increasing the efficiency and air flow rate.
• Fitted with a electrical anti-freeze heater (in unit base) to avoid the formation of ice and encourage the drainage of condensate during heating operation.
• Electronic expansion valve.

Main hydraulic components

• Inverter pump.
• Plate heat exchanger.
• Expansion tank
• Safety valve.
• Flow switch.
• Water filter supplied (mandatory installation).

Regulation

Adjustment via a multi-language touch-screen control panel:

• Management of a 3 way diverting valve (not supplied) for the production of domestic hot water.
• Management of a 2 way valve (not supplied) for shutting off part of the system.
• Weekly programming in time periods.
• Auto-restart function.
• Emergency operation (a supplementary heat source may be activated).
• Quick hot water function, for quickly heating domestic hot water.
• Weather dependent mode function for climate control.
• Quiet function for reduced noise operation (programmable with a timer).
• Condensation check
• When the anti-legionella cycle is activated (it’s easily set via the control panel), the whole tank is heated once a week to a temperature (max. 70 °C) that weakens the bacteria responsible for the infection.

Special golden fin coil

Unlike normal batteries, this special golden epoxy coating silicon free is able to protect the heat exchanger against rust and corrosion, in areas where the air has a high salt content.

Smart APP Ewpe

The system is equipped standard with the Wi-Fi module; using this module and the app for iOS and Android devices (available free on Apple Store and Google Play, the system can be directly controlled from a distance on your smartphone or tablet. Remote control is possible via Cloud, using a wireless router connected to the Internet.

ACCESSORIES

• DHWT300S: (220-240V~50Hz) DHW storage tank in enamelled steel. Single-phase power supply, tank capacity 300 litres with main and secondary coils and 3 kW back-up electric heater. Magnesium sacrificial anode. Indoor installation, as indicated in the installation manual.
• HMICB15: Connection cable for the control panel. Cable length 15m.
• IC-2P: Connector for communication via Mod Bus or VMF -485LINK. Accessory compulsory if combined with VMF-485LINK, or for third party supervision systems.
• VMF-485LINK: Expansion to interface the unit with the VMF communication protocol, making it possible to manage it from the VMF E5 or VMF-E6 supervisors.

For more information about VMF system, refer to the dedicated documentation.

Connection with VMF-485LINK

Connection with third party supervision systems
