S&P SILENT-100 CHZ DESIGN Manual

Introduction

The installation and settings must be done only by a Qualified Electrician
The SILENT DESIGN extractor fan range is manufactured to the high standards of production and quality as laid down by the international Quality Standard ISO 9001. All components have been checked and every one of the final products will have been individually tested at the end of the manufacturing process.
On receipt of the product we recommend that you to check the following:

1. That it is the correct model.
2. That the details on the rating label are those you require: voltage, frequency...

The installation must be carried out in accordance with the electrical standards in force in your country.

Installation

Before installing and wiring the unit, ensure that the main supply is disconnected.
Fig. 1:

1. Protection grille
2. Connection terminals
3. Outlet with backdraught shutter
4. Cable entry

The SILENT DESIGN is suitable for wall or ceiling mounting and can either discharge directly to the outside or via an individual ducting system (see Fig. 2).

The unit can be mounted on the wall or ceiling using the 4 wall plugs and the screws provided.
Make a hole in the wall or ceiling of diameter:

• SILENT-IOO DESIGN: 105 mm
• SILENT-200 DESIGN: 125 mm.
• SILENT-300 DESIGN: 160 mm.

If the unit is to be installed with individual ducting, use a standard duct of diameter:

• SILENT-IOO DESIGN: 100 mm
• SILENT-200 DESIGN: 125 mm.
• SILENT-300 DESIGN: 150/160 mm.

Ensure that there are no obstructions to the airflow and that the impeller turns freely.
Fix the extractor to the wall in such a way that it is not distorted in order to avoid noise generation or problems with the rotation of the impeller. Make sure that the backdraught shutter opens freely and has not being damaged in transit. Introduce the mains cable through the cable entry (4) and fix it to the wall.
Connect the electrical wiring as set out below and then mount the protection grille (1).

Electrical connection

The SILENT DESIGN is an extractor designed for a single phase supply, with voltage and frequency as indicated on the rating plate of the unit. The units are manufactured with double electrical insulation (Class Il) and therefore they do not need an earth connection.
In addition to the switch shown in the installation drawing/diagram, there must be an All Pole switch in the fixed wiring with a contact opening of min 3 mm.
The electrical cable must enter the SILENT DESIGN through the cable entry (4).
Once the cable has been introduced proceed using the electrical wiring diagram applicable to the selected model.

SILENT CHZ DESIGN

Models provided with an electronic humidistat which can be adjusted from 60% to 90% RH (Relative Humidity) and with a timer, adjustable between 1 and 30 minutes. The desired humidity level and run on time are selected by means of 8 dip-switches placed on the printed circuit board, and easily accessible. Each dip-switch has two positions [ON (1) and OFF (0)] which are selected with the small plastic screwdriver supplied with the fan:
The functions of these dip-switches are:

• Switch 1: "Interval" function selection (yes or no)
  
• Switches 2 and 3: Interval time settings between 4, 8, 12 and 24 hours
  
• Switches 4 and 5: Humidistat settings between 60, 70, 80 and 90%
  
• Switches 6 and 7: Over-run timer settings between 1, 5, 15 and 30 minutes
  
• Switch 8: Start-up timer function (yes or no)
  

Automatic operation
The extractor is connected to the main supply with only two wires. (Fig.4) (Fig.6) The humidistat causes the extractor to operate automatically when the humidity level in the room is higher than the set level. The extractor will stop automatically when the humidity drops below the selected level (-5% or +10%) and after the selected period set on the over-run timer.

"Interval" functions
This function is useful when the extract fan is installed in very wet (near the sea) or the ambiance exceeds the set level for a very long time. To prevent the fan to run for hours without stopping, the "Interval" function allows the fan to switch off automatically one hour after it began to run. The extractor keeps switched off during the set time for interval function. If the humidity level is still above the set level when the time interval is over, the extract fan switches on again and run during one hour. To select this function put the dip-switch 1 to position "ON"
To adjust the set time for interval function, use the dip-switches 2 and 3
When, on the contrary, the extract fan never switches on because the humidity level is always very low or it is improperly installed (above heating appliance, behind a door, in an area with no air movement) putting the 1 dip-switch interval function to position "ON", the fan switches on automatically during 1 hour and then it keeps switched off during the set time for interval function. This function causes the fan to run whatever the humidity level.
To select this function put the dip-switch 1 to position "ON"
To adjust the pre-set time for interval function, use the dip-switches 2 and 3.

Automatic operation with external switch to override the extractor


(Fig.3) (Fig.7) The extractor is connected to the main supply with three wires.
Operation as previous "Automatic operation", with the facility to override the humidistat by means of the light switch when the humidity level in the room is lower than the selected level. In this case the extractor continues to operate for the selected period of time (over-run timer) after the switch light has been switched off.
ATENTION: When the humidity rate is above the selected value, the automatic option takes precedence over the manual and the unit cannot then be switched off using a switch.

Start-up timer function
In this operation, the "start-up timer function" allows to delay the extractor startup for a period of 50 seconds. So that, for example, the fan does not switch on if the usage time of the bathroom is less than 50s.
If you exceed the 50s and the humidity level in the room is below the selected level, the fan switches on, and when the light switches off, runs the time set by the timer. This function is selected with the dip-switch 8.
