1. INTRODUCTION
1.1 Description of Control System
The control system is specifically designed for MCKT-HPX AHUs. The control algorithm, making use of up to 5
temperature sensors in total, enables highly efficient heat recovery from the air extracted from rooms. Application of
EC motors in MCKT-HPX 1 and MCKT-HPX 2 as well as AC motors controlled with inverters in MCKT-HPX3 also
enables stepless adjustment of fan RPM in entire control range.
The control system supports the heat pump as well as option’s air dampers and preliminary electric heater.
The room panel equipped with 4-line display, enables communication between a user and the control system
installed in the MCKT-HPX. A panel equipped with temperature sensor can be located in any room, which facilitates
operation and improves the comfort of usage.
The application of the MODBUS RTU protocol enables connecting the controller to the facility’s BMS system and
remote control and adjustment of the AHU.
1.2 Functions of control system
The control system is in charge of the following functions:
• Power supply: 1×230VAC – MCKT-HPX 1 i 3×400V MCKT-HPX 2 i MCKT-HPX 3
• power supply, protection and independent control of fan motors, heat pump compressor
• 24VAC power supply of optional air damper actuators
• power supply of control panel
• 2× communication ports RS 485
• 3x analog outputs 0-10V
• 5x non-voltage relay digital outputs, switched
• 5x digital temperature sensor inputs
• 4x non-voltage digital inputs
• 2x analog inputs 0-10V
• 2x quick transistorized output (PWM)
• weekly calendar with possible 4 time zones for each day
1.3 Electric protection
The control system has to be energized in accordance with the wiring diagram and has to be protected with a circuit
breaker with an appropriate rating for the receivers used.
Protection of fans, heat pump compressor and compressor casing heater depend on their output and are provided on
appropriate wiring diagrams.
1.4 Communication
The automatic control system enables communication with the BMS system using the MODBUS RTU –RS485
protocol.
Summary of variables in point 9.
2. SUPPORTED DEVICES
2.1 Fans
The control system enables independent control using 0÷10V voltage signals of air supply and air exhaust fans
equipped with 1-phase EC motors for MCKT-HPX 1 i MCKT-HPX 2 and 3-phase (3x230V) AC with inverters for
MCKT-HPX 3 size. It also enables providing power supply and protecting each of them individually.
2.1.1 RPM adjustment of MCKT-HPX 1 and MCKT-HPX 2 fan motors
The controller provides a 0÷10V signal directly to the EC motor
2.1.2 RPM adjustment of MCKT-HPX 3 fan motors
The controller provides the 0÷10V signal to the inverter which in a proportional way changes frequency of the fan
motor current.
AHUs are equipped with inverters with 1×230V 50Hz power supply, which control fan motors powered with 3x230V
50Hz. Each inverter is equipped with control panel shown below.

2.2 Heat exchanger
The control system controls defrosting of the cross-flow heat exchanger. When the controller receives a signal from
the temperature sensor (Tr) installed at the exchanger's air exhaust outlet regarding a drop of this temperature below
the setting (factory default: 0°C), it initiates the defrosting mode. It consists in turning on the preliminary heater, heat
pump compressor and air supply fan. Once the situation is under control (temperature above the setting) and after
3minutes, the AHU switches back to the normal operation mode.
2.3 Heat pump
The control system contains a complete algorithm of heat pump control with reverse operation option.
It covers the following functions:
- Turning on/off the compressor
- Turning on/off the solenoid valve controlling the compressor
- Turning on/off the 4-way valve switching the system operation
- Read out of high pressure gauge alert
- Read out of low pressure gauge alert
- Controlling the compressor casing heater
The MCKT-HPX AHU can be equipped with the preliminary electric heater (optional), which heats up fresh air
and ensures correct operation of the heat pump at low external temperatures (below -5°C).
2.4 Filters
The pressure gauges installed at filters indicate filter contamination and the need to replace them. When excessive
pressure drop on any of the filters is detected an alarm signal is displayed.
It is necessary to plan filter exchange/cleaning. The system should not operate for a longer with contaminated filters
as it can cause damage of the heat pump and/or fans' motors.
2.5 Optional devices
The MCKT-HPX control systems enable control of other devices which are not provided as standard AHU equipment.
They contain:
2.5.1 Preliminary electric heater
Preliminary electric heater energized and controlled with a separate module.
Power supply for the heater MCKT-HPX 1 – 1×230V/50Hz, for MCKT-HPX 2,3 – 3×400V/50Hz.
Heaters electric data – see point 10.
It is recommended to use pressure gauge pf air supply fan connected to appropriate terminals of electric heater
module.
2.5.2 Inlet and outlet air dampers
Inlet and outlet air dampers with on/off-controlled actuators, with 24VAC power supply.

3. CONTROL PANEL
The main component designed for communication with the controller of the control system is the control panel (it is
also possible to control the equipment with the BMS in the MODBUS RTU protocol).
Picture 3 Control panel view
3.1 Assembly and connection of control panel
The DEN16-C panel is energized with 12VDC supply from the Unibox controller. The power supply and control is
carried out both using 4-strand communication cable. It can be terminated at each side with RJ11 connectors (4-pin,
size 6) or can be connected directly to COM1 clamp connection. The cable with RJ connectors should be interlaced
as shown:
Picture 4 RJ clamp terminal view
If cables longer than 5 meters are used, it is recommended to use twisted-pair cables, eg. UTP
(1st pair: +12V, G0; 2nd pair: A, B).
