PAC-M100-A Replacement

Refer to the above Figure 1. PAC-M100-A M-NET Wiring:

1) Remove the supply blower access panel.

2) Remove the cover from the PAC-M100-A.

3) Disconnect the M-NET wires from the TB5 terminal block.

4) Unplug the Modbus wire from the CN2 connector.

Cut the plug off the end of the Modbus wire.

5) Remove wires from box and then remove the box.

6) Attach PAC-M200-A to the wall of blower compartment.

7) Run Modbus and M-NET into the PAC-M200-A through the cable glands.

Refer to next page 6, Figure 2. PAC-M200-A M-NET Wiring:

8) Attach the MODBUS to terminal strip TB485

9) Attach the M-NET wires to terminal TB5 as shown in the wiring diagram.

230 volt power supply is not required when replacing PAC-M100-A with the PAC-M200-A.

Power is provided by M-NET.

10) Secure cable glands, set DIP Switches and address dials the same as the PAC-M100-A for replacement.

11) Replace cover on PAC-M200-A.

Two (2) types of rotary switch setting:

- Setting addresses 1 to 9 and over 10, and

- Setting branch numbers.

NOTE: Do not use branch setting switch for this unit.

Examples how to set addresses:

- If address is “3”, leave SW12 (for over 10) at “0”,

and set SW11 (for 1 to 9) to “3”.

The rotary switches are all set to “0” when shipped from

the factory. Use these switches to set unit addresses and

branch numbers as well.

NOTE: Indoor unit M-NET addresses vary depending on

design. Refer to sample systems, page 7.

- If address is “3”, leave SW12 (for over 10) at “0”,

and set SW11 (for 1 to 9) to “3”.

The rotary switches are all set to “0” when shipped from

the factory. Use these switches to set unit addresses and

branch numbers as well.

Control Methods

AUTO (Outdoor Reset) Control

System Supply Air will operate based on the Outdoor Reset Sengs

Control method when the PremiSys is providing air into VFR Indoor Units

1. Leave the switches in factory default posion on the interface control board

2. Set Microprocessor "Supply Temp Set Point" source to BMS

3. Set Microprocessor "ON/OFF" control source to BMS

4. On central controller, set the system group to ON

5. On central controller, set the system group mode to Auto

The Set Temp. cannot be changed while operang in the auto mode

The current Set Temp. will be displayed

Note:

Mode prohibit can be ON or OFF

Controlling System Supply Air Temp from the central controller

System Supply Air Temp will operate based on the seng in the central controller

Control method when air is directly into the space

1. Leave the Dip switches in factory seng posion on the interface control board

2. Set Microprocessor "Supply Temp Set Point" source to BMS

3. Set Microprocessor "ON/OFF" control source to BMS

4. On central controller, turn the system group to ON

5. On central controller, turn the system group mode to Cool or Heat

The Set Temp. for Cool or Heat mode will be the same

The unit will determine the Mode automacally

6. Set the Set Temp. to a temperature that represents the average space Set Temp.
