Basics
The Alfredo module for the A/C, is a Hydronic unit, that adds to the A/C the capability, to economically heat the water-based Central-Heating.
Now the A/C can supply, both cooling and comfort heating, at 70% energy savings compared to Gas, at 70% savings.
The unit is supplied as a kit, currently designed to be an external Add-On, the A/C, with minimal integration, for ease of installation.
A streamline integration will simplify preparations and installation.
Details
The system is composed of:
The Hydronic unit, which should be placed near the A/C external unit.
The A/C interface unit, which should be placed near the internal A/C unit
User and Technician control: WIFI or wired
The Module operates as follows:
The user may program different settings for heating (times, Zones, Temperature).
On detecting a time to heat the central-heating, and the room temperature is lower than set, the module will turn the water-heating ON.
On heating, the Module will perform a process whose main function is to command the A/C to turn ON to heating, and divert the hot refrigerant to the water heat-exchanger, Circulating to the heating-circuits (Radiators or radiant-floor).
When water heating ends, The Module performs an Off-process, and returns the A/C to the previous action it was doing (Air-Heat / Air-Cool / Off).
If the A/C was air-heating, then Air-Heating stops during water-heating.
The hydronic unit:
1) The thermal heart – the heat-exchanger (HE), from refrigerant to circulating-water. Valves and controls direct the refrigerant fully, either to the refrigerant-water HE or to regular air-evaporator .
2) Refrigerant connections are fully external to the Evaporator and the Condenser units. 2-pipe connection to the Condenser unit, and 2-Pipe connection to the Evaporator unit.
3) The units are fully self-contained for water flow, with a pump to circulate to the Central-Heating, and pressure-reducer.
Due to different sizes, the expansion-tank is external, and a 5V control is provided for an additional pump (for larger heating areas).
4) The module Contains the control unit of the MAOZ system.
5) Extreme weather backups:
* control for an optional addition of an auxiliary electric-heating.
6) With the installer in mind, the unit contains the circulation pump (calculated for a 100 sqm apartment), Flare refrigerant connections with 1-spanner operation, Pushfit non-spanner water connections, telephone crimp-plugs for fast electrical signal-wiring, and base-plate for simple hanging
7) Supplied in various heat-exchanger sizes (4,7,9,12,15, 18 kW), to connect to the differing needs of A/Cs, with refrigeration-pipes are in 3/8 – 3/4″ accordingly
8) User / Technician control is via WIFI or wired.
Heating Zones – up to 2 zones.
9) Optional connections are for:
* An additional pump (for larger area connections),
* Control over an external Auxiliary heating source (for extreme conditions)
* A “skirt” to cover the piping .
10) Size WxHxD : 40 x 63 x 32 cm.
* Power: The whole unit is 24VDC, Max 50W
The AC-DC 75W converter is supplied
The A/C Interface unit Combi module:
Its purpose is to communicate and control the A/C internal unit, a visual status of the Module, and internal operations
On command, the unit communicates to the A/C using the regular IR interface (like any remote control).
For easy installation, the IR LED is supplied on a wire, to allow the installer to locate the unit at will, thread (Through the grill air-inlets) to place the LED near the IR Receiver.
The unit can “learn” to communicate with virtually all A/CsIn some units, a simple connection to the A/C electronics card is required.
The unit contains the WIFI module to communicate with the home WIFI.
A reset button is also available, and LEDs show the status of operation.The unit is wire-connected to the Hydronic unit.
Size WxHxD : 8X8X3.
