Toshiba R410A service manual Applicable Controls, Setup of external static pressure

11 APPLICABLE CONTROLS

Setup of external static pressure

•Select with shifting of the short plug on the indoor unit microcomputer P.C. board.

Matching with the resistance (External static pressure) of the duct to be connected, be sure to set up the tap exchange according to the basic operation procedure

(1 → 2 → 3 → 4 → 5 → 6 ).

•For the item code in Procedure 3, specify [5d].

•For the set data in Procedure 4, select the setup data of static pressure outside of the machine to be set up from the table below.

(Exchange by wired remote controller)

Set data			External static pressure
0000	40Pa			Standard (At shipment)
0001	70Pa	*1		High static pressure 1
0003	100Pa	*2		High static pressure 2
0006	20Pa			Low static pressure

*1: For SM1401BT, set 65Pa.

*2: For SM1401BT, set 90Pa.

When mounting a filter sold separately, be sure to set up the tap exchange according to the type of filter.

In this case, also follow to the basic operation procedure (1 → 2 → 3 → 4 → 5 → 6 ).

•For the item code in Procedure 3, specify [5d].

•For the set data in Procedure 4, select the setup data of filter to be incorporated from the table below.

Set data	Filter sold separately
0000	Standard filter (At shipment)
	Optical regeneration deodorizing filter
0001	High-performance filter 65, 90
	Deodorant filter Ammonia deodorizing filter

When using wireless remote controller

To exchange the static pressure, there is a method other than the abovementioned method by wired remote controller, which is to shift the short plug on the indoor microcomputer P.C. board as shown in the following table. Adopt this method in case of using a wireless remote controller, etc.

*However, after exchanging once, be careful to shift the short plug to the standard position (At shipment) in order to return to the standard setup (follow to E2PROM setup) though the setup for high static- pressure 1, high static-pressure 2, or low static- pressure can be arbitrarily performed.

It is necessary to rewrite data from the wired remote controller sold separately in the set data “0000”.

*1 Resistance of high-performance filter 65 and 90, deodorant filter, or ammonia deodorizing filter is equivalent to 30Pa. Therefore, set the resistance (external static pressure) of a duct to be connected to 40Pa.
