Congratulations with the purchase
of your STC Controller
The STC is a software-controlledclimatecontroller.The
STC issuitableforoneortwofans.The STCalsohas a
LDR (light sensor) and an NTC (temperaturesensor).
User’s Manual:
- Make sure The STC is securely attached
to on a wall.
- Attach the NTC (if possible) in the middle
of your room.
- Connect the fan or fans. Fans of the same
m3 don’t give under pressure to your room.
Plug the STC into an earthed power outlet.
turn the left-hand knob (1) to the desired
speed. Minimum speed 20% to 60%. If the
fans start to hum gently, turn the left-hand
knob (1) a little higher until it is corrected.
A to low fan speed can damage the fan or
fans or the STC.
Turn the middle knob (2) to the desired
maximum speed (60% to 100%).
Set the switch (5) to the automatic
position. on position (1).The fans will now
start running.
Now set the desired temperature with
the temperature knob (4). The NTC
now controls the processor for optimum
temperature control in your room.
With the delta button: bottom right button
(3) you now can set the margin for the
temperature. You setting the margin will
prevent switching between the min / max
setting too quickly. As a result, your fans
will last longer and make less noise. We
recommend 3 to 4°C.
Switching the night mode on
Humidity can rise sharply during the night.To keep this humidity
within acceptable values, you can choose to use the night
mode.The STC switches up in small steps to a Max 80%, once
per hour, for a few minutes.Thereby lowering the moisture in the
air. When de rubber cap is removed from the light sensor.The
STC will now operate in night/ day mode.The green LED (6) will
now light up. Showing the STC is in night mode. Switching the
night mode off By turning the switch (5) to the zero position and
then waiting 5 seconds and then back to the Automatic mode
switchable mode (1), the night mode is switched off.The green
LED (6) will now be switched off.
100% SCHEME.

switch (5) to zero position, wait 5 seconds and then move
switch (5) in position (2).The fans will now run at 100%

Attention (cal-min potentiometer)
The STC’S are being programmed for most
used fans. However switching the minimal
speed down is possible. For this purpose turn
the Cal-Min potentiometer (under the socket
template 7 on the right hand side).Turn left
for minus and right for plus.Turn down the speed
in such a manner that the fan will always keep
running.
Troubleshooting
If the STC fails to run:
1. Switch off the supply and check the
fuse (8) in the STC.
2. If the fuse (8) is OK increase the
minimum fan speed.
3. Re-connect the STC and retry.
If the STC still fails please contact the retailer the
