ELECTRONICS OPERATION ALGORITHM
It is possible to control the fan rotation speed without options by voltage,
as well as by thyristor controllers.
The speed controller is purchased separately.
Warning! When adjusting the voltage, make sure there is no unusual noise
or vibration at reduced motor speed.
The motor current may exceed the rated current during voltage regulation.
The fan is equipped with a thermal switch with no self-reset.
To reset the thermal relay:
- Switch off the power supply.
- Find and eliminate the cause of overheating.
- Make sure the motor has cooled down to operating temperature.
- Switch on the power supply.
The TT Silent-M … T fan starts operation when the control voltage is
applied to the LT input terminal by an external switch (e.g. switching on the
room light).
After the control voltage is off, the fan continues to operate within the set
time period adjustable from 2 to 30 minutes by the timer.
To adjust the fan turn-on delay time, turn the control knob T clockwise to
increase and counter-clockwise to decrease the turn-on delay time
respectively.
Warning! The timer circuit is under mains voltage. Make adjustments only after disconnecting the fan from power mains. The fan is supplied with a special plastic screwdriver for adjusting the fan settings. Use it if you want to change the fan turnoff delay time or the humidity threshold. Using a metal screwdriver, knife, etc. for adjustment may damage the electronics board.
The TT Silent-M … U/U1/U2(n) fan is equipped with an electronic module TSC (speed controller with an electronic thermostat) for automatic motor speed (air flow) control depending on the air temperature.
The terminal compartment incorporates 2 control knobs:
- presetting the speed
- setting the threshold for the electronic thermostat
The thermostat operation indicator is located on the fan cover. It lights up
when the air temperature exceeds the set value.
To set the thermostat threshold, turn the temperature knob clockwise to
increase the value and counter-clockwise to decrease the value. To set the fan
speed (air flow), rotate the speed control knob in the same way.
The fan operating logic may be based on temperature or timer indications:
TT Silent-M … U(n): The fan switches to the maximum speed as the room air
temperature exceeds the set point. As the air temperature drops 2 °C below the
set point or if the initial temperature is below the set point, the fan
operates with the set speed.
TT Silent-M … U1(n): The fan switches to the maximum speed as the room air temperature exceeds the set point. As the air temperature drops down below the set point, the timer starts a 5-minute countdown and then the fan switches to the set speed.
TT Silent-M … U2(n): The fan switches to the set speed as the room air temperature exceeds the set point. As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the fan is turned off.
The TT Silent-M … P fan is equipped with a speed controller that enables switching the fan on/off and smooth speed (air flow) regulation from minimum to maximum value.
TECHNICAL MAINTENANCE
The fan maintenance periodicity is at least once per 6 months.
Maintenance steps:
Disconnect the fan from power supply and make sure electricity has been turned off. Disconnect an air duct on both sides of the fan.
| Clean the fan with a soft dry cloth or a brush.
---|---
Wipe the fan surfaces dry.
| Connect an air duct on both sides of the fan. Supply power to the fan.
CAUTION! Do not allow water or liquid come into contact with electric components!
