External I/O Specifications; Selecting The External Static Pressure; Setting Addresses; Sensing Room Temperature With The Built-In Sensor In A Remote Controller - Mitsubishi Electric CITY MULTI PEFY-P140VMHS-E Installation Manual

9.4. External I/O specifications

Caution:
1. Wiring should be covered by insulation tube with supplementary insulation.
2. Use relays or switches with IEC or equivalent standard.
3. The electric strength between accessible parts and control circuit should
have 2750 V or more.

9.5. Selecting the external static pressure

Four levels of external static pressure (50 Pa/100 Pa/150 Pa/200 Pa) are available for selection.
Set the setting either by using the switches on the control board (SW21-1, SW21-2, and SW21-5) or from the function selection screen on the remote controller.
Notes:
• When the static pressure setting was set from the remote controller, the actual setting and the switch setting on the control board may not match because the
latest setting from the remote controller overrides the previous setting. To check the latest static pressure setting, check it on the remote controller, not on the
switch.
• If the static pressure setting for the duct is lower than that for the unit, the fan of the unit may repeat start/stop, and the outdoor unit may remain in a stopped
state. Match the static pressure settings for the unit to that for the duct.

 To set the external static pressure from the function selection screen on the remote controller (Only PAR-30MAA)
Follow the instructions below and the instructions detailed in the remote controller manual for how to set the switches.
1. Set the function setting No. 32 (Switch setting/Function selection) to "2".
2. Set the function setting No. 8 and No. 10 to appropriate values, according to the external static pressure.

9.6. Setting addresses

(Be sure to operate with the main power turned OFF.)
[Fig. 9.5.1] (P.6)
<Indoor controller 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)
The branch number assigned to each indoor unit is the port number of the BC controller
to which the indoor unit is connected.
Leave it to "0" on the non-R2 series of units.
• 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 the Data Book.

9.7. Sensing room temperature with the built-in sen-
sor in a remote controller
If you want to sense room temperature with the built-in sensor in a remote controller,
set SW1-1 on the control board to "ON". The setting of SW1-7 and SW1-8 as nec-
essary also makes it possible to adjust the air flow at a time when the heating ther-
mometer is OFF.
Note:
To perform the auto cooling/heating operation, use the built-in sensor in a re-
mote controller or the optional remote sensor.
