ACCOUNT UNIT 2 CIRCUITI IDRAULICI E VALVOLE DI RICCARDO FERRERO

Compact

Hot water immediately available thanks to recirculation: saving water, heat and Energy. (Pat. Pend.)

The reduced size of the unit, that in addition to incorporate all the functions, allow installation near use. The integration of these features with the recycling of the hot sanitary water allows to have an immediate delivery of hot sanitary water with significant savings in energy, water and calories.

Operation An adjustable thermostat connected to a probe placed at the point of dispensing hot water allows to maintain a constant predetermined minimum value of its temperature.

The thermostat has a differential temperature of about 5 ° C., as this value is reached, the thermo-stat operates as follow.

:Series 10 unit, with instant production of hot sanitary water: The thermostat activates the heating pump that circulates the water until it reached the predetermined temperature at the entrance of the heat exchanger.

Series 20 unit, with the management of sanitary hot water storage: The thermostat controls the opening of the thermoelectric valve connected to the accumulation tank via a pipe. The valve in the open position, activates the hot sanitary water pump that circulates the water until restoration of temperature.

When the hot sanitary water has reached the set temperature, the thermostat stops the pump and closes the valve of recirculation.

A check valve allows the flow of hot water recirculation only towards the boiler.

In order to avoid contamination by legionella is sufficient to maintain the boiler temperature at 55 °C.

SAVINGS

1. The energy saving is ensured by the activation of the pump for a short time. 2 . The saving of water is made by the recycled water . 3. The saving of calories is given by the hot water that returns to the accumulation. 4. If the hot sanitary water in the accumulation is eg. at 55 °, but the usage is at 40 ° can be set this value, a low temperature allows a lower dispersion. For units in the version with thermostatic mixer, when the hot water from the pipe passes in the mixing valve will not be mixed, it will be mixed when it arrive from the accumulation.

Modular, easy to install.

The units are composed of three different modules , and variously performed according to their functions and needs of the user, as follows:

1. Management or hot sanitary water and cold water. With termostatic mixer and re cycling of hot water.

2. Management of input primary hot water: Interception, flow regulation, filtration, one-way control of the flow. Flow controller by a motorized ball valve, watertight motor IP65. 3. Interception on boiler's primary flow return: accounting and management of the calories consumed. Flow accumulation with lung before the calorie counter.

Installation note. Connection to pipes can be made by releasing the module from the hardware, unscrewing the screw and then tilt the unit to the tube, screw them. Easier still is. 1. Unscrew the valve and fittings from the module.

2. Unhook the hardware module and move it.

3. Insert the valves in the pipes, tighten the fitting.

4. Screw the fitting of valves and fittings to the module.

5. Hang up the hardware module.

A further advantage of the separate modules: the possibility to position the unit directly on the pipes, compensating for any errors in cutting of them.


Total insulation, minimal loss heat.

Even the isolation is complete and unique.

Instructions.

Leave pipe insulation leaning against the insulating box.

When installation is complete, push back the insulation tube and paste it to insulating box with a touch of suitable adhesive. The insulation of the pipes is all one with the box insulation.

The photo shows the unit SAT16, with recirculation inserted.

See how unit shows without and with the lid on.

ELECTRONIC AND ELECTRICAL WIRING BOX

REDUCED ELETRONICAL CONTROL BOX

It can handle up to seven zones or different environments, each indicated by a LED that lights up when the circuit is activated. A LED indicates the presence of electric power and another the activation of the pump in the boiler room. The others the request of warm from the seven zone. Each of the seven commands is equipped with a timer that received the request pulse of heat from a room thermostat, activates the opening of electrothermal valve, but delay the activation pulse of the pump to allow the opening of the valve. The boxes are complete and need only be connected to the distribution network, to various external devices: thermostats or programmable thermostats installed in the rooms, pump and equipment in the boiler room, the thermoelectric valves when placed in a separate environment. The outputs of the cables are twelve, six on each side, watertight.

The box is arranged to directly manage one or two base zone. Each base zone controls a valve ball which distributes the heating fluid in his zone Each base zone can handle an unknown number of circuits, both at high and at low temperature. These sub zone are controlled by thermoelectric valves driven directly by thermostats.

The standard box is designed for the management of all the unit with any shape: basic unit, with management and distribution of high and low temperature heating.

The valve is equipped with a motor (with seal water proof IP65) which is operated by an electronic circuit (patented) that allows the user to program it in various ways: management of multiple entries or more outputs to choice. Possibility to use it as a mixing valve, etc.

In the standard version for satellites: heating, cooling, management or production of hot water. Valve connects alternately heating and hot sanitary water production. The request of hot sanitary water is a priority on the heating / cooling. As soon as the request ceased the valve switches to heating, if required. If the heating is turned off the valve switches on the production of hot sanitary water. Valve can be use for other applications, eg. as well as switch on the two sides also
