Selecting The Static Pressure; Setting Addresses; Sensing Room Temperature With The Built-In Sensor In A Remote Controller - Mitsubishi Electric CITY MULTI PEFY-P40VMH-E Manuel D'installation

Caution:
Wire the power supply so that no tension is imparted. Otherwise disconnec-
tion, heating or fire result.

9.4. Selecting the static pressure

Type 40 - 140
The external static pressure can be changed over as required. For the selection of
the static pressure, insert an attachment between the connector of the motor lead
wire and the control box.
The relationship between the attachment and the external static pressure is shown
below.
Attachment (Red) ....... External static pressure 200 Pa
Attachment (Blue) ...... External static pressure 50 Pa
Type 200 · 250
The external static pressure can be changed over as required.
For the selection of static pressure, replace the connector of the motor lead wire by
the connector (blue) inside the control box for insertion.

9.5. Setting addresses

(Be sure to operate with the main power turned OFF.)
[Fig. 9.5.1] (P. 4)
<Address board>
• There are two types of rotary switch setting available: setting addresses 1 to 9
and over 10, and setting branch numbers.
1 How to set addresses
Example: If Address is "3", remain SW12 (for over 10) at "0", and match
SW11 (for 1 to 9) with "3".
2 How to set branch numbers SW14 (Series R2 only)
Match the indoor unit's refrigerant pipe with the BC controller's end con-
nection number. Remain other than R2 at "0".
• The rotary switches are all set to "0" when shipped from the factory. These
switches can be used to set unit addresses and branch numbers at will.
• The determination of indoor unit addresses varies with the system at site. Set
them referring to technical data.
Notes:
Please set the switch SW5 according to the power supply voltage.
• Set SW5 to 240 V side when the power supply is 230 and 240 volts.
• When the power supply is 220 volts, set SW5 to 220 V side.
9.6. Sensing room temperature with the
built-in sensor in a remote controller
If you want to sense room temperature with the built-in sensor in a remote control-
ler, set SW1-1 on the control board to "ON".
