6 Heat recovery unit controller manual controller HRU-MinistCONT-Man Function Description Availability Fan speed control Fan speed boost Filter clogging indicator Automatic air flow bypass Electric heater control Sensor (VOD) Sensor (Humidity) Freeze protection Preheater control BMS connectivity Modbus connectivity Programmable week control timer Air supply and air exhaust fans are provided with a 3-speed control system. This function increases the fan speed: Option 1: Press the BOOST button on the control panel Option 2: Activated with an external dry relay input or an external 230 V input (activated e.g. by a lamp switch in the kitchen, bathroom, etc.) on the controller s PCB. Two filter clogging indicator options: Option 1: The filter clogging indicator counts down the unit's operating time to a preset value. When the preset value is reached, a filter change request indicator is activated on the control panel. Option 2: Filter clogging can be monitored with a pressure switch. When the filter reaches the clogging limit, the pressure switch activates a filter change request indicator on the control panel. The filtered fresh air is supplied indoors, bypassing the heat exchanger. The interfaced electric heater can have the output automatically switched between a maximum of 2 levels the selection of which depends on the desired temperature setting and the actual indoor temperature. The fans are operated continuously by the control output of a CO2 sensor or an air quality sensor. The fans are operated continuously by the control output of an indoor air humidity sensor. If the outdoor temperature is low, the freeze protection function is activated to protect the heat exchanger from freezing. If the outdoor temperature is low, the fresh air supply is treated by a preheater upstream of the unit. This function protects the heat exchanger from freezing. IN: The unit can be turned on and off using an external control panel. OUT 1: Unit status output OUT 2: Unit fault alarm output This feature allows operating all controls of the unit via a PC or a central automation system. The unit can be programmed to operate at specific hours in a weekly cycle. 3 speeds (all fans) (High / Medium / Low) Optional Optional Optional Data logging This function allows logging all available operating options of the unit. Fire mode This function activates a special operating status in the case of a fire alarm. Alarms - Filter change required - Fan failure - Preheater failure - Heater failure (Error code display) Child lock Locks the control keypad to prevent inadvertent operation. 690

Alnor ventilation controller configuration pane: The wizard's steps guide the user through the commissioning and local network configuration of the device. Heat recovery unit start and stop: ON / OFF 692

9 Heat recovery unit controller HRU-MinistCONT-Wifi Controller Heat recovery unit work mode selection: adjust the continuous operation of the unit to your needs, or use the predefined options as follows: STANDARD MODE: continuous air change. Enables work mode selection for the AIR SUPPLY fan and the AIR EXHAUST fan. AIR EXHAUST MODE: controls the air exhaust fan only. Fan work modes: speed 1, 2, 3 or OFF. Start the function to extract stale air from the area and return to the air change mode by selecting STANDARD. 693

10 Heat recovery unit controller HRU-MinistCONT-Wifi Controller AIR SUPPLY MODE: controls the air supply fan only. Fan work modes: speed 1, 2, 3 or OFF. Start the function to supply fresh air indoors and return to the air change mode by selecting STANDARD. VOD MODE: in the Ventilation On Demand mode, the air supply and air exhaust rates depend on the humidity readout from the optional indoor air humidity sensor connected to the heat recovery unit. The sensor is sold separately. Remote temperature setting: choose the indoor temperature for the room. Indoor air temperature: shows the actual temperature of the air exhausted from the area, which is changed by the controller via the heat recovery system to match the remote temperature setting. The outdoor air intake temperature. The temperature of the air supplied by the heat recovery unit to the area. 694 Alarm code: displays the error code of the heat recovery unit. (See the error code definitions in the User Manual.) BY-PASS FUNCTION: the heat recovery unit supplies fresh and filtered outdoor air bypassing the heat exchanger. When this indicator is checked, the By-Pass Mode is running. ONLINE: shows the status of the data connection between the controller and the heat recovery unit. When this indicator is lit, the data connection is correct.
