8 1. 2. 3. CONDENSATE DRAINAGE HRV 120 SR must be connected to sewage system. Connect the drain pipe, the U-trap (not included) and the sewage system with metal, plastic or rubber hoses with the minimum hose slope angle 3. Fill the system with water prior to connecting the unit to power supply and make sure the U-trap is always filled with water. Check the drain system for correct operation and unhampered drainage to prevent condensed water accumulation and overflow. The unit is designed for indoor installation and operation at the temperatures above 32 F (0 C). If the expected ambient temperatures are below 32 F (0 C), the drain system must be heat-insulated and frost protected. DO NOT CONNECT SEVERAL DRAIN PIPES FROM SEVERAL UNITS TO ONE U-TRAP! DIRECT CONDENSATE DRAINAGE OUTSIDE WITHOUT CONNECTION TO SEWAGE SYSTEM IS NOT ALLOWED. DRAIN PIPE HOSE min 3 U-TRAP PIPE SEWAGE CONNECTION TO POWER SUPPLY DISCONNECT THE UNIT FROM POWER SUPPLY PRIOR TO ANY ELECTRIC INSTALLATION OPERATIONS. ELECTRICAL WIRING SHALL ONLY BE PERFORMED BY A QUALIFIED ELECTRICIAN. THE NOMINAL ELECTRIC PARAMETERS ARE SHOWN ON THE NAME PLATE.

9 WARRANTY WILL NOT COVER EQUIPMENT DAMAGE OR FAILURE THAT IS CAUSED BY IMPROPER INSTALLATION. The unit is rated for connection to single-phase ac 120 V/ 60 Hz power supply source. The unit is equipped with a power cable and a plug and can be connected to any standard grounded outlet. The power cable is pre-wired to the terminal by default. The unit must be connected to power supply via the external automatic circuit breaker with magnetic trip integrated into the fixed wiring system. The trip current of the automatic circuit breaker must be not below the rated current consumption (minimum 3 A). Mounting place of the circuit breaker must ensure sufficient access for emergency shutdown of the unit. The cutout fuse is used for overload protection in case of an overload or a short circuit. To replace the cutout fuse disconnect the unit from power supply source, troubleshoot an overload or a short circuit and then replace the cutout fuse. Check the unit for operation. 1 2 WIRING DIAGRAM SW1 TR1 ~120 V, 60 Hz ~120V ~12V ~12V external connections interface A2 0-16 BH16 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 24VAC 12VAC GND12V;24V N 120VAC L120VAC Green control board A1 1 2 3 4 5 PE 3 white black N L SW1 SW1 6 7 8 9 BH16 37-52 10 11 12 10 11 12 MED LOW 24VAC 13 14 15 16 17 Rb Ud1 Ud2 GND Vcc brown white 19 18 20 Vcc Ut GND white brown OUT A GND +E 1 2 3 SW2 Low Stanby Med temperature sensor yellow 10 12 11 M3 black red black M2 (L) M2 (C) M2 (N) 21 22 23 24 C2 25 C2 26 M1 (L) 27 M1 (C) 28 M1 (N) 29 C1 C1 30 N EA2/O EA1 EA2/Z 31 32 33 34 35 36 SW3 SW4 black brown blue black brown blue 31 32 34 3 2 1 3 2 1 blue brown black Y/G PE C2 C1 blue brown black Y/G PE 34 C3 32 31 M2 exhaust fan M1 supply fan UNIT CONTROL Operation modes of the unit: Permanent operation or standby mode; High-speed ventilation mode. The unit is controlled using a three-position switch. It enables operation of the unit in the Low Speed Mode, Medium Speed Mode or Standby Mode, thus providing total air quality control. The unit changes to HIGH speed mode on a signal from external connected control units. The LED2 indicator glows during the unit standstill and active power supply. The LED2 indicator goes down and the LED1 indicator goes on. Enter the Speed Setup Mode to adjust supply and exhaust fan speed. Individual speed adjustment for each fan is possible over

Remote control panel (thermostat). Remote control panel (thermostat) functions: Turning the unit on/off Speed control Displaying room temperature Programming scheduled operation 2. CO 2 sensor. Recommended for use in office buildings and public premises. When carbon dioxide concentration exceeds the set point, the unit changes to the High Speed Mode. 3. Humidistat. The humidistat is used for indoor humidity control. When indoor humidity increases above the set point, the unit switches to the High Speed Mode and runs with the high speed until the humidity falls down below the set point. The humidity set point is adjustable. 4. Mechanical. In case of the timer activation the unit changes into the High Speed Mode. 5. Switch. As the switch is turned ON the unit changes into the High Speed Mode and reverts to the permanent Low Speed Mode when the switch in turned OFF. 6. Speed controller 0-10 V. Connect the speed controller to the external terminals 6, 7 and 8. The speed controller enables smooth fan speed control and speed setting. The fan speed is directly proportional to the control voltage in the range of 20% up to 100%. The control signal from the speed controller has the priority over all other controls, expect for the fire control alarm panel. 7. Fire control alarm panel. Connect the fire control alarm panel to the external terminals 9 and 10. Once the dry contacts are closed the unit has an emergency shutdown. 8. External control. The terminals 35 and 36 for external equipment are located on the control panel. The terminals are connected to the contacts that are closed during the unit activation and are closed during its deactivation. This way the enabling signal for activation of the fan coil, the compressor and condensing unit, the electric actuator of the external

11 air damper or any other compatible climatic equipment is sent. Control signal parameters: maximum current 1A; maximum voltage 250 V. Access to the control circuit board and connection of the external control equipment: unscrew the front part of the control panel; remove the cover; connect the external control unit to the control board; assemble the control panel in the reverse order. 1. 2. 3.

Adjust the fan speed using the EXHAUST and FRESH speed controllers. 4. Save the settings by pressing and holding MODE button, till the LED1 and LED2 indicators go out. To leave the speed setup mode without editing press shortly the MODE button. Example: adjust the MED speed.

12 Press the MODE button three times. LED1 and LED2 indicators start blinking three times as you enter the setup mode. Adjust the exhaust and supply fan speed. Press and hold the MODE button. After that the LED1 and LED2 indicators light up and the speed setting is saved. DEFROSTING MODE. The defrosting mode is used for freeze protection of the heat recovery core. The freeze protection mode is activated by default and may not be deactivated. There are two ways to activate the defrosting mode by pressing the MODE button: In recirculation mode the the supply operates with the maximum speed, the exhaust fan is off and the recirculation damper is open. In ventilation mode without recirculation the exhaust fan operates with maximum speed, the supply fan is off and the recirculation damper is open. No recirculation (air exhaust only) Recirculation OUTDOOR INDOOR OUTDOOR INDOOR ON OFF OFF ON MAINTENANCE DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS! Regular maintenance should be performed every 3 months as follows: 1. Filter maintenance. Dirty filters increase air resistance and reduce supplied air volume to the room. Clean the filters as often as required, but at least 3-4 times per year. Clean the filter with a vacuum cleaner. Replace the filter after the second cleaning. For new filters, contact the product Seller. 2. Heat recovery core maintenance (once per year). The regular filter maintenance may not completely prevent dust ingress into the heat recovery core. The heat recovery core must be regularly cleaned to maintain high heat recovery efficiency. Remove the heat recovery core from the unit and wash it with soap

13 water solution. Let the heat recovery core dry out and re-install it into the unit. 1b. 2b. 3b.! 4b. 3. Fan maintenance (once per year). Regular filter and heat recovery core maintenance may not completely prevent dust ingress into the unit fans. Clogged filter reduce supplied air volume to the room. Clean the fans with a soft cloth or a brush. No water and abrasive detergent, sharp objects or solvents are allowed for cleaning to prevent the impeller damage. 4. Drain line maintenance (once per year). The drain line may get clogged by extracted particles. Check the drain line functioning by filling the drain pan with water and clean the drain line if required. 5. Air ductworks maintenance (once in 5 years). If degraded performance is still noticeable after following all maintenance guidelines it is recommended that the ductwork be checked and cleaned if necessary. 6. Inspection of exhaust louver shutters and supply diffusers (as required). Remove the disc valves and the louver shutters and wash those with warm detergent solution. Do not change the positions of the disc valves and the louver shutters.

14 TROUBLESHOOTING Trouble Probable reason Remedy The fan is not started. The unit is not started, the 1-E01 and І.E02 LED lights glow. Circuit breaker tripping during starting the unit.
