• Do not install the product in a place where acid or alkali liquid or special sprays are used.
• Failure to do so may result in electric shock or abnormal operation.

WARNING

• Do not remodel or repair the ERV interface module yourself.
• Failure to do so may result in product malfunction, electric shock, or fire, so contact a service center for repair.
• When disposing of an ERV interface module, contact a service center.
• Do not move or reinstall an installed ERV interface yourself.
• Failure to do so may result in electric shock or fire.

CAUTION

• Make sure that water does not permeate inside the ERV interface module.
• Failure to do so may result in electric shock or fire.
• Do not connect power cable to the control cable terminal.
• Failure to do so may result in fire.

ERV interface module installation

Products and components

Diagram of connection between an ERV interface module and a Ventilator

1. Attach the ERV interface module in the space within the electrical parts of the ventilator.
2. Connect the power cable and communication cable of the ERV interface module.
   • If you use upper level controller (such as DMS, OnOff controller, etc.) with the ERV interface module installed, use of centralized control (installation option 1 of the ERV – SEG5) must be set as “Enable”.

Connecting commercial ERV

• Commercial ERV has screw-type F1, F2, V1, and V2. Connect DC power cable and communication cable to the terminals by cutting the ends of the cables (on ERV PBA side) and connecting them to the terminals.

• You should separate power cable and communication cable. (Abnormal operation of the product may occur due to the electric problem.)

• ERV interface module (MIM-N10) supports connection between NASA communication upper
  level controller Non-NASA communication ventilator, Non-NASA communication upper level controller NASA communication ventilator, NASA communication upper level controller  NASA communication ventilator but it does not support communication between Non-NASA communication upper level controller Non-NASA communication ventilator.

• You should be aware that power may not be supplied to ERV and interface module if power polarity of V1 and V2 is connected opposite.

Set the address of ERV interface module.

The address for each ERV interface module should be set differently

CAUTION

• The cable length between the upper controller and the farthest ERV interface module should be within 1000 m.
• You should switch off the power supply before installation.
• The wiring should be installed in accordance with electric wiring regulations and should beplaced inside the wall so that users cannot touch them

Setting option switch and address switch

1. Swich for setting address : Address switch, set the address within 0~F (0~15) (Address between each ERV interface module should be set differently)
2. Option switch

Setting option switch and address switch

About setting the main address manually and installation condition

1. Connecting NASA communication upper level controller
   • Automatic address: Address of the interface module is assigned randomly.
   • Manual address: Address of the interface module is assigned by address switch of the ERV interface module.
2. Connecting Non-NASA communication upper level controller.
   • When connecting Non-NASA communication upper level controller, address of the interface module should be assigned by address switch of the ERV interface module.
   • Connection between Non-NASA communication upper level controller  Non-NASA communication
     ERV is not supported

NOTE

• The default setting of option switch is OFF for both SW4 and SW5.
• When upgrading the program, switch off the power supply of ERV interface module first and set SW4-2 to ON status before proceeding upgrade regardless of the installation condition.
• After completing the upgrade, set the SW4-2 correctly according to installation condition before supplying the power

ERV interface module installation

When installing 16 Ventilators

Checking operation

LED Indication

1. When resetting the power supply, the ERV interface module will not respond to the upper level communication for up to 10 minutes. If the communication with lower level (e.g. : between ERV interface module and the ventilator) is detected as valid communication, Y-GRN LED will blink. (Please wait until the communication between the ERV interface module and the ventilator becomes normal.)
2. When the upper level communication (e.g. Between an OnOff controller and an ERV interface module )is detected as valid communication, the RED LED will blink.

Checking operation

7-SEGMENT indication

1. When initializing power supply , will be indicated after indicating the program cord.
2. After receiving valid communication more than once , will be indicated.
3. When the communication is normal, the MAIN ADDRESS of the ventilator that can be controlled by the ERV interface module is indicated in order.
4. When there is no communication between the ventilaotr and the ERV interface module for more than 3 minutes, will be indicated alternately.
5. When there is no communication between an ERV interface module and an upper level controller for more than 3minutes, will be indicated alternately.
6. When the ERV interface module tracking is not complete, will be indicated alternately.
7. When there’s error on EEPROM of the ERV interface module, will be indicated alternately.
8. When same address was set to multiple ERV interface modules, will be indicated alternately.
9. When more than 16 ventilators are installed, will be indicated alternately.
10. When ventilators and indoor units are installed together, will be indicated alternately.

Notes on interface module installation

1. Address of the ventilator can be set between 00~47 (when manually set) and up to 16 units can be connected to one ERV interface module. For automatic address setting, address will be automatically assigned to each unit between 00~15.
2. Indoor unit and ventilator should not be installed to the same communication line (F1,F2).
3. Interface module for an air conditioner is different, make sure MIM-N01 model is connected to an air conditioner.
4. Function controller(MCM-A100) is not compatible.
5. If you have replaced the ERV interface module (due to failure) anytime after setting the centralized control level from the upper level controller, you must set the centralized control level again after replacing the ERV interface module.
6. Power of the ERV interface module must be reset after changing the installation condition of the ventilator.
   • When changing the number of installed units or address of the ERV
