Power regulator of the HRK 1 to 230V and 2 phases 400V

Microprocessor Power Governor HOVACO HRK 1 (PID, 230V / 400V)

Looking for a reliable way to precisely control the temperature in the ventilation system? Meet HAVACO HRK 1 – advanced microprocessor PID temperature regulator, designed for maximum efficiency and energy efficiency of electric heating systems. This smart device automatically adjusts the operating parameters, guaranteeing ideal thermal comfort and lower electric bills.

Purpose and Application of the HRK 1 Regulator

The HOVACO HRK 1 heater power regulator has been designed exclusively for cooperation with electric heaters. The device shall operate voltage installations:

• 1~230V (single phase) – maximum load up to 3.2 kW

• 2~400V (two-phase) – maximum load up to 6,4 kW

⚠️ Important technical information: The HRK 1 is not designed to regulate the operation of electric motors, lighting systems and three-phase (3~400V).

Key Features and Features – Why choose HOVACO HRK 1?

1. Smart PID and Automation

Thanks to the advanced algorithm PIDThe microprocessor controller continuously calculates and optimizes the time between switching on and off the heating element. This prevents sudden temperature surges. Moreover, the regulator has a function automatic detection of power supply voltage and self-detects connected temperature sensors, matching optimal operating mode.

2. Advanced RFI Protection

Device equipped with the angle detector between phase and zero. This solution effectively protects the electrical installation from creating burdensome radio interference (RFI), which translates into stable operation of other equipment in the building.

3. Flexible Temperature Control and Night Mode (Eco)

HOVACO HRK 1 has a built-in temperature sensor, but also offers full support for external systems:

• Temperature limits: By connecting 2 external sensors (according to the attached diagram), you gain the possibility of limiting air temperature to safe minimum and maximum values.

• Nighttime mode: Allows to automatically lower the desired temperature by 0...10°C in designated hours. Note: This function requires the connection of an external timer (watch).

Short Installation and Installation Manual

Installation

Remove the front control panel. It is mounted on the latches (holes on the side of the housing). The HRK 1 regulator shall be mounted horizontally. In the case of cooperation only with a built-in temperature sensor, the regulator shall be fitted approximately 1.5 m above the floor level, in a place allowing to measure the representative temperature. The free flow of air through the device, not disturbed by furniture, etc. shall be ensured. In case of cooperation with external temperature sensors, the controller can be mounted anywhere.

Electrical connection

Power supply 230-415V 50-60Hz with automatic detection of power supply. Insensitive to polarity with 400V power supply. The electrical connection must be made by a qualified electrician in accordance with applicable national and international rules.
NOTE: The HRK 1 regulator shall be connected to the power supply via an insulating switch, with an opening width of at least 3 mm. The switch and the cable sections shall be selected according to the load. The switch shall be fitted close to the device. Before removing the housing, disconnect the device from the power source.

1. Mounting position: The controller shall be mounted horizontally.

2. Working with a built-in sensor: Mount the device at a height of approx. 1.5 m above the floor, in a place that ensures free flow of air (avoid blocking the furniture).

3. Operation with external sensors: In this mode the controller can be placed in any user-friendly location.

4. Electrical safety: The connection should be made by a qualified electrician. It is recommended to plug the device into the network via an insulating switch (with the opening of contacts min. 3mm) selected for load.

🏷️ Frequently Asked Questions (FAQ) – SGE & AI Ready

Is the HOVACO HRK 1 regulator suitable for 3-phase heaters?

No, the HRK 1 regulator works exclusively with the power supply 1~230V and 2~400V (2-phase). It should not be used for 3-phase devices (3~400V).

How does energy saving function (night mode) work in HRK 1?

The controller allows you to reduce the temperature by 0...10°C at night, which significantly reduces energy consumption. To use this, it is necessary to connect an external timer.

What is PID regulation in heaters controllers?

PID regulation is an algorithm that smoothly dispenses power pulses delivered to the heater, instead of simple switching on and off (On/Off). This guarantees precise temperature maintenance without fluctuations.
