VENTS TT PRO 315 Inline Mixed Flow Fans
This user’s manual is a main operating document intended for technical,
maintenance, and operating staff. The manual contains information about
purpose, technical details, operating principle, design, and installation of
the TT PRO unit and all its modifications. Technical and maintenance staff
must have theoretical and practical training in the field of ventilation
systems and should be able to work in accordance with workplace safety rules
as well as construction norms and standards applicable in the territory of the
country.
All user’s manual requirements as well as the provisions of all the applicable
local and national construction, electrical, and technical norms and standards
must be observed when installing and operating the unit. Disconnect the unit
from the power supply prior to any connection, servicing, maintenance, and
repair operations. Only qualified electricians with a work permit for
electrical units up to 1000 V are allowed for installation. The present user’s
manual should be carefully read before beginning works. Check the unit for any
visible damage of the impeller, the casing, and the grille before starting
installation. The casing internals must be free of any foreign objects that
can damage the impeller blades. While mounting the unit, avoid compression of
the casing! Deformation of the casing may result in motor jam and excessive
noise. Misuse of the unit and any unauthorized modifications are not allowed.
Do not expose the unit to adverse atmospheric agents (rain, sun, etc.).
Transported air must not contain any dust or other solid impurities, sticky
substances, or fibrous materials. Do not use the unit in a hazardous or
explosive environment containing spirits, gasoline, insecticides, etc. Do not
close or block the intake or extract vents in order to ensure the efficient
air flow. Do not sit on the unit and do not put objects on it. The information
in this user’s manual was correct at the time of the document’s preparation.
The Company reserves the right to modify the technical characteristics,
design, or configuration of its products at any time in order to incorporate
the latest technological developments. Never touch the unit with wet or damp
hands. Never touch the unit when barefoot. This unit is not intended for use
by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the unit by a person responsible
for their safety. Children should be supervised to ensure that they do not
play with the unit. Connection to the mains must be made through a
disconnecting device, which is integrated into the fixed wiring system in
accordance with the wiring rules for design of electrical units, and has a
contact separation in all poles that allows for full disconnection under
overvoltage category III conditions. If the supply cord is damaged, it must be
replaced by the manufacturer, its service agent, or similarly qualified
persons in order to avoid a safety hazard. If the cord set is damaged, it must
be replaced by a special cord set available from the manufacturer or its
service agent.
CAUTION:
In order to avoid a safety hazard due to inadvertent resetting of the
thermal cut-out, this unit must not be supplied through an external switching
device, such as a timer, or connected to a circuit that is regularly switched
on and off by the utility. Ensure that the unit is switched off from the
supply mains before removing the guard. Precautions must be taken to avoid the
back-flow of gases into the room from the open flue of gas or other fuel-
burning appliances.
- THE PRODUCT MUST BE DISPOSED SEPARATELY AT THE END OF ITS SERVICE LIFE. DO NOT DISPOSE THE UNIT AS UNSORTED DOMESTIC WASTE

OPERATION GUIDELINES
The fan is rated for connection to single-phase AC 220-240 V/50 Hz or 220 V/60 Hz power mains. The unit is rated for continuous operation. The arrow on the fan casing must match the air direction in the system. Ingress protection rating against access to hazardous parts and water ingress is IPX4. The unit is rated as a Class II electrical appliance. The fan is rated for operation at the ambient air temperature from +1 °C up to +40 °C. To comply with the ErP 2018 regulation, a local demand controller and speed controller must be used.

MOUNTING
The fan is suitable both for horizontal or vertical mounting on the floor, on
the wall or on the ceiling
The fan can be installed independently or as part of a set with parallel or
in-series connection
Install minimum 1 m long air duct on the intake spigot side in case of
horizontal fan mounting or a hood in case of vertical fan mounting. The outlet
spigot must always be connected to the air duct. The fan mounting sequence is
shown in
The fan wiring diagrams are shown in
Some fan models are equipped with a plastic limit stop in front of the L1
terminal. Remove the limit stop for connection to the L1 terminal.
Designation:
L1 – minimum speed terminal
L2 – maximum speed terminal
QF – automatic circuit breaker
S – external speed controller
ST – external switch (for example, a light switch)
X – input terminal
CONTROL LOGIC
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 MIX PRO (R)V fans are equipped with a speed
switch
The TT PRO T fan starts running after the external switch supplies control
signal to the LT input terminal (for example, during turning the light on).
After removal of the control signal the fan continues to run within the set
time (adjustable with the turn-off delay timer from 2 to 30 minutes). To
adjust the fan turn-off delay time, rotate the control knob T clockwise to
increase and counter-clockwise to decrease the turn-off delay time
respectively
Warning!
The timer circuit is under mains voltage. Disconnect the fan from power
supply prior to any adjustment operations. The fan delivery set includes a
specially designed plastic screwdriver for adjustment of the fan parameters.
Use exclusively the delivered plastic screwdriver to adjust the turn-off delay
time. Do not use a metal screwdriver, knife, etc. for adjustment operations
not to damage the circuit board. The TT PRO U/U1/U2(n) fan is equipped with an
electronic TSC control unit (speed controller with electronic thermostat) for
automatic speed control (air flow control) depending on the air temperature
. The terminal box cover incorporates 2 control knobs:
- for setting the fan speed;
- for setting the thermostat set point. The thermostat LED light is located on the fan casing. The thermostat LED glows as air temperature exceeds the set point. To set the thermostat set point rotate the temperature control knob clockwise to increase or counter-clockwise to decrease the temperature set point accordingly. To set the fan speed (air flow) rotate the speed control knob in the same way.
The fan functioning logic may be based on temperature or timer controls:
TT PRO U(n): the fan switches to the maximum speed as the room air
temperature exceeds the set point. As the air temperature drops down 2 °C
below the temperature set point or if the initial temperature is below the set
point, the fan operates with the set speed.
TT PRO U1(n): the fan switches to the maximum speed as the room air
temperature exceeds the set point. As the room air temperature drops down
below the temperature set point, the timer starts 5 minutes countdown and then
the fan switches to the set speed.
TT PRO U2(n): As the indoor air temperature exceeds the set point, the
fan switches to the maximum speed. 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 PRO P fan is equipped with a speed controller that enables switching
the fan on/off, smooth speed (air flow) control from minimum to maximum value
TECHNICAL MAINTENANCE
The fan surfaces must be regularly cleaned (once in 6 months) from dirt and
dust .
Disconnect the fan from power mains prior to any maintenance operations. To
clean the fan, use a soft cloth or a brush wetted in a mild detergent
solution. Do not allow water or liquid come into contact with electric
components .
Wipe the surfaces dry after cleaning.
