Manual Addressing for Pipe Detection Example (Zone Setting)

Zone control is when two (2) or more indoor units are connected to one (1) valve of the heat recovery unit. For this application, set the
controls with the multiple indoor connections using the rotary switch; i.e., only the rotary switch changes the same valve set condition and set
indoor units connection.
1. Set the DIP switch on the corresponding valves and the rotary switch to "0".
2. Set the number using the tact switches.
3. If additional indoor units are connected to one heat recovery unit valve, increase the rotary switch setting by one (1) and set the number
using the tact switches.
4. To verify the number of the corresponding valve, turn the DIP switch to ON and set the number on the rotary switch.
5. One heat recovery unit valve can support up to eight (8) indoor units (rotary switch settings 0~7). An error will display if more than eight
(8) indoor units per heat recovery valve are set with the rotary switch.
6. Return the rotary switch to its original setting (heat recovery unit number settings) after all pipe settings are complete.
7. The rotary switch setting value of the number of indoor units connected to "FF" prevents a malfunction. Example: Where three (3) indoor
units are connected to valve 1; rotary switch settings are 0,1,2 and 3,4,5,6,7 with "FF". (Prerequisite for manual pipe detection: The cen-
tral control address of each indoor unit must be preset differently using its wired remote control.)
Example: An indoor unit with a central control address of "11" is connected to valve no. "1" of an heat recovery unit.

• The procedure described above must be performed for all heat recovery unit valves.
• Valves that do not have connected indoor units must be addressed with a number that has not been used. (Valves will not work if the ad-
dress numbers are the same.)

Operation: None
Display: None
Operation: Turn DIP switch No. 1 on to address valve No. 1.
Display: Existing value saved in EEPROM is displayed on SSD.
• Operation: Set the "10" digit to the number in Group High data of the wired
remote control connected to the corresponding indoor unit with the valve No.
1 by pressing left tact switch.
• Display: Digit increases with the number of times the tact switch is pressed,
shown on left SSD.
• Operation: Set SW05M to "1".
• Display: Former set value is shown on SSD.
• Operation: Set SW03M, SW04M, and SW05M to "1".
• Display: Set value is shown on SSD.
• Operation: Turn DIP switch No.1 to off to save the address of valve No. 1.
• Display : Set value from previous step disappears; SSD is blank.
• Operation: Addressing the return valve of the heat recovery unit.
• Display: SSD is blank.
