Destech HRC Controller is an embedded system that contains a microcontroller and can manage complex functions with special software inside. The control card processes the data such as relative humidity, temperature, air quality it receives from the sensors and decides how much the environment should be ventilated. In line with this decision, the motor sends the signals it produces to the driver and ensures that the fans work at certain speed and time intervals. It plays an important role in the energy saving and energy management of the heat recovery device.

 Key Features

Function	Definition
Fan Speed Control	Allows control of the speeds of the device fans. Manual: 3 steps speed control of EC and AC fans Single fan mode Speed control of 2 fans separately Automatic With humidity, CO2 and different sensors Constant flow / constant pressure function
Boost Function	The fan speed of the device is temporarily set to the fastest position in case of need. Manual: Via Panel Automatic: On the control board
Filter Function	Warns the user when the device’s filters become dirty. Alternative-1: Time-bound Alternative-2: Mechanical
By-Pass Function	By-Pass provides damper control.
Rotor Function	In ventilation devices with rotor-type heat recovery exchanger, it controls the rotor’s motor on/off.
Electric Heater Control Function	Performs stage control of the electric end heater.
Aqueous type Battery Control Function	Controls the aqueous type cooler or heater/coolant battery.
Frost Protection Function	It is the freeze protection of the Heat Recovery heat exchanger. Alternative-1: By-Pass damper Alterntaif-2: Fan speed control Alternative-3: Electric preheater step control
Preheater Function	Performs stage control of the electric preheater used as a precaution against freezing.
Room Temperature Function	It allows the selection of the return air temperature or control panel temperature as the room temperature.
BMS Function	It allows simple control of the device from a central unit and monitoring of the situation. BMS: Starting/stopping the device independently of the controller. Run out: Get “Device is running” information  Fault out: Get “Device fault” information.
Modbus Function	It controls all the functions of the device from the central automation panel or via the computer.
Time Function	It allows the device to be changed to the working position or to turn on and off at certain times on a weekly basis.
Log Function	Records all working locations of the device.
Fire Function	Changes the operating conditions of the device in the event of a fire.
Child Lock Function	Turns off the use of keys in the control panel (key lock) Alternative-1: Manual Alterntaif-2: Time-dependent
Wireless Communication	Allows the connection of the wireless (RF) user panel and wireless room sensors to the device.
IoT Function	It allows the characteristics of the device to be tracked over the internet.
Service Interface	The device allows adjustment of all operating parameters and functions.
