Fan Settings. SPEED SETTING The fans are factory set to bathroom speed, but have two speed settings for different applications. Select either kitchen or bathroom speed by connecting the jumper between the centre and kitchen or bathroom speed pin on the jumper (see Figure F)
LVCV4S /LVCV4R– see figures E and F.
• The pre‐set humidity operation is factory set at approximately 75% Relative Humidity (RH), but can be adjusted between 65% and 85% RH by control HUM.
• The over‐run timer is factory set at 15 minutes but can be adjusted from 30 seconds to 30 minutes by control TIME.
• The over‐run timer also sets the length of time the fan runs when activated by a ‘fast’ increase in humidity.
• Turn the controls clockwise to increase RH or time and anti‐clockwise to decrease.
Using the fan. The fan will run continuously at its trickle speed setting as set during the installation procedure.
• Automatic mode‐ The fan automatically adjusts to slow changes in natural humidity levels without operating the fan. If the humidity levels increase at a rate slower than 5% RH in 5 minutes, up to the pre‐set humidity level, the fan will not be triggered by humidity. This is to prevent nuisance triggering of the fan. If humidity levels increase quicker than 5% RH in 5 minutes the fan will increase in speed to an interim boost speed setting. When relative humidity drops the fan continues to operate for the adjustable time delay.When the humidity is above the pre‐set humidity level the fan will run at a higher speed until the humidity drops below the pre‐set value. If humidity levels do not drop within 5 minutes the fan will further boost to its maximum speed setting until humidity drops.
• External operation‐ Use the external boost switch (if fitted). When the fan is switched off, the fan continues to operate for the adjustable time delay then goes into automatic mode.
All Fans Re‐fit the front cover/baffle assembly by hooking in the top first, and then swing the cover down to clip into place.
Hour run meter All fans incorporate an hour run meter that allows the installer to measure the actual running time of the fan after installation. The meter records continuous power supply on time and displays this via an on‐board red LED that always flashes to indicate the total number of hours the supply has been on (see fig. H).
