VENTS P3-1-300 is a series of wall-mounted switches for controlling multi-speed fans with a 230 V single-phase power supply. The series mainly includes the P3-1-300 for three-speed fans. Control is step-based – the user selects one of the pre-set motor speeds rather than adjusting the speed smoothly.

P3-1-300 is not a smooth speed controller. It is designed specifically for fans that come from the factory with three separate motor speeds. Through the rotary switch, the user selects low or high speed or turns the fan off completely.

This makes it suitable for a number of two-speed VENTS fans, including models from the TT series, where the manufacturer lists it as an external accessory for controlling the two-speed motor.

Operating mode

Control is as simple as possible:

OFF – fan is off

1. - low speed
2. - medium speed
3. - high speed

 

P3-1-300 switches between the pre-set speed leads of the motor. Therefore, it must be used only with a fan whose motor is designed for three-speed operation.

Compatibility

P3-1-300 is designed for three-speed fans.

It is important that the specific fan has separate electrical leads for low, medium, and high speed. If the motor is single-speed and allows adjustment by changing the voltage, another type of controller is required, for example from the RS-1 series.

Installation and protection

P3-1-300 is designed for indoor wall mounting in a suitable mounting box. The manufacturer expressly warns against:

• direct water spraying;
• rain;
• direct sunlight;
• installation directly next to heating appliances and other heat sources. Electrical connection must be carried out with the power supply switched off and by a qualified person.

VENTS RS-1-400 is an electronic controller for stepless speed control of single-phase fans and other voltage-controllable AC motors. It operates at 230 V / 50–60 Hz, supports a load of up to 1.8 A, and allows for simultaneous switching on/off and speed regulation via a single rotary knob. It is suitable for wall mounting in standard or specialized installation boxes.

RS-1-400 is designed for ventilation systems where manual and stepless speed control of a single-phase fan is required. Using the control potentiometer, the user can decrease or increase the voltage supplied to the motor, thereby adjusting its RPM.

Several fans can be connected simultaneously to a single controller, provided that their total current draw does not exceed the maximum allowable 1.8 A. The controller also includes protection via a replaceable thermal fuse and a filter against transient interference.

Operation

The RS-1-400 regulates the speed by changing the voltage supplied to the motor. Operation starts from a pre-set minimum value and allows for a smooth increase up to maximum speed. The minimum speed can be adjusted via a potentiometer on the electronic board.

This is important for fans that should not be reduced below a certain speed to ensure the motor remains stable and properly cooled.

Controlling multiple fans

A single RS-1-400 can control more than one compatible fan simultaneously, if:

the total current of all connected fans is ≤ 1.8 A.

For example, with two fans drawing 0.6 A each, the total load is 1.2 A, which remains within the allowed range.

It is also important to verify that the specific motor is suitable for voltage-based speed control.

Protection

The controller features:

• a replaceable thermal fuse for overload protection;
• a filter against transient electrical interference;
• a casing with IP40 protection. IP40 means the product is intended primarily for dry indoor environments and not for direct exposure to water or outdoor weather conditions.

Installation

The RS-1-400 is designed for indoor wall mounting. It can be installed:

• in a standard round electrical box;
• in an MKN-3 surface-mount box;
• in an MKV-4 flush-mount box. Installation and electrical wiring must be performed with the power supply disconnected and in accordance with the manufacturer's diagram.
