"SILA RCT MINI PLUS" is 3-speed (Min, Max, Holiday) residential heat recovery unit + mechanical bypass + humidity sensor. The unit is designed to continuously remove stale air from rooms by means of a system of fixed piping and grilles. The heat is recovered from the air suctioned from the room by means of a high-performance heat exchanger, which transfers is to the incoming cool air. The flow rate of the ventilation can increase up to "Max" mode, for example if there is a high amount of humidity in the room. The extracted air is discharged outside by means of a single duct to a grille.

The frame is made of galvanized painted steel. The internal sides of the housing are made in expanded polypropylene.

The heat recovery unit is also equipped with a filter maintenance warning system. (for more information see the paragraph on FILTER CLEANING).

Use

Appliance is automatically managed by an electronic control system. Appliance can automatically choose the most suitable operating mode, depending on the outside temperature.

When the appliance is switched, both motors will reduce speed for 3 minutes to allow repositioning of the bypass valve. After, motors will start up again. NOTE: this is a normal system procedure and should not be perceived as a malfunction.

"Heat recovery" Function

This kind of function is normally activated, except when:

- automatic functions: "No-Frost", "By-Pass" and "Post-ventilation" are active;

- the manual function: "By-Pass MAN" is active.

Stale air is expelled outside by means of an outside duct while, at the same time, renewed air is also extracted from the outside. This renewed air is heated by the combined action of the air/air heat exchange. The renewed air enters into the room by the Cleaned air duct.

"No-Frost" Function

The function is activable if 2 minutes are left after Appliance turning On.

“No-Frost” function is automatically active when the Appliance check a too low External air temperature, for a certain time. When the function is active:

- the message "No-Frost" appears on the display;

- User can not change ventilation Speeds;

- "Program" function is NOT enabled.

The main scope of the "No-Frost" function is to avoid appliance damaging, because of too low temperatures.

When the message "Alarm!" and "Lock!" appears on the display: it represents a "no-frost timeout".

This means that “No-Frost” procedure has proved insufficient and the appliance goes into protected mode for one hour, with the motors off, following which it will restart automatically.

NOTE: Restarting is automatic and don't need User presence.

"By-Pass" Function

This type of operation is automatically set and it is useful to ventilate the apartment without heat transfer. With the bypass valve open, air can be extracted directly from inside, without passing through the heat exchanger. The flow of air vented to the inside continues to pass through the heat exchanger, that will not be effective anymore.

“By-Pass air Temperature” represent the “Desidered air temperature”: according to this, the Appliance activates/deactivates the bypass valve. User can select the “By-Pass air Temperature” into a range of temperatures:

from 15°C to 30°C. The preset "By-Pass air Temperature" value is 18°C (default).

NOTE: The "By-Pass" automatic function is deactivated when:

- External air temperature is less than 15^ C;

- "No-Frost" function is active.

Example: Autumn case (sunny afternoon)

External air Temperature = 23°C;

Indoor air Temperature = 20°C;

Bypass air Temperature = 24°C.

Appliance extracts the External air (hot) without heat exchanging with the Indoor air (cold). In this way, thanks to environmental conditions, a “free heating” is provided.

ENGLISH

Example: Spring case (morning)

External air Temperature = 16°C;

Indoor air Temperature = 20°C;

Bypass air Temperature = 18°C.

Appliance extracts the External air (cold) without heat exchanging with the Indoor air (hot). In this way, thanks to environmental conditions, a “free cooling” is provided.

"By-Pass" Valve check

A Valve check is performed:

1) When the appliance is switched on both motors will reduce speed to allow repositioning of the by-pass valve. After, motors will start up again.

2) After 24 h from the last By-Pass valve opening Appliance forces a By-pass activating to check the effective position of the valve:

- if the valve is opened, force the opening;

- if the valve is closed, force the closing.

This is a normal system procedure and should not be perceived as a malfunction.

NOTES

- Every time, during By-Pass opening and closing (max 180 sec), Appliance automatically reduces fan-ventilators speeds to the 20%, in order to help the By-Pass valve movement.

- In case of Temperature sensors anomalies, By-Pass valve will stay preventively closed.

When the function is active, the message "By-Pass" appears on the display: see "Home Page" in the "Operation with remote control display" section.

"Post-ventilation" Function

This kind of function is automatically activate after:

- every time Pre-Heater is turned off (if Pre-Heater installed) both motor-fans active (about 3 minutes) to avoid overheating;

- every time you turn the Appliance off indoor air is extracted at the max speed (about 2 minutes) to avoid condensate presence on the heat exchanger.

This is a normal system procedure and should not be perceived as a malfunction.

"Program" Function

Special mode of operation: manually enabled and allows the user to program weekly air speeds. In fact, it allows you to assign up to 6 time bands with different speeds, including stopping the equipment. When the function is active, the message "Progr." Appears on the display: see "Home Page" in the "Operation with remote control display" section. However, the speeds can be manually changed even at specified intervals: in this case the word "Prg" will flash for 30 minutes and after it will go back to the setted speed of the weekly time band. If in this 30 min any other function will change the speed, this 30 min timer will go back to 0. For more details on setting the time slots and dates, see "PRG Crono" in the "Operation with remote control display" section. For details on how to activate / deactivate the function, see "Activating / deactivating Program" in the "Operation with remote control display" section.

ENGLISH

"Holiday" Function

Special mode of operation: manually enabled and useful if the user leaves the room for a longer period of time.

Operation includes:

- fixed "30% less than the Minimum" speed (no other speeds, no OFF equipment);

- environment sensors not enabled (remote inputs not activated);

- bypass always closed.

When the mode is active, the message "Holiday" appears on the display: see "Home Page" in the "Operation with remote control display" section.

NOTE: Activating the Mode "Holiday" will be deactivate other product functionings/selections.

To re-activate other product functionings/selections, need to deactivate the Mode “Holiday” before.

For more details on how to activate / deactivate the function, see "Activating / deactivating Holiday" in the

"Operation with remote control display".

"By-Pass MAN" Function

Special mode of operation: manually enabled and useful if you want to force air replacement without heat recovery.

The operating principle is the same as: "By-Pass" function.

NOTE: If manually enabled, the "By-Pass MAN" function will remain active for 12 h. After this period, the "By-Pass MAN" function will come back to: Not enabled.

NOTE: (In case of "By-Pass MAN" Enabled) However you can manually deactivate the function, setting "NO" on "By-Pass MAN Menu". After Deactivating, the operating principle will be come back the same of "By-Pass" function.

NOTE: In case of "No-Frost" function active, you can not manually activate the "By-Pass MAN" function.

When the function is active, the message "By-Pass" flashing appears on the display: see "Home Page" in the "Operation" and use ". For details on how to activate/deactivate the function, see "Activating/deactivating By-Pass MAN" in the "Operation with remote control display" section.

"Quiet" Function

This is a particular operating mode: if the user needs to temporarily disable the appliance from running at Vmax (for example to exceed the RH relative humidity threshold set in the dedicated menu), this function is available which can be programmed by the user. In the dedicated menu, you will have to set the daily time slot in which the equipment will be inhibited from switching to Vmax mode in order to limit the noise within the pre-established time slot.

This function is very useful during the night time slot
