Air volume control technical manual Indoor unit air volume can be controlled with a opening-closing of a damper by either an analog input (CN2A) or a contact input (CN105) to the air conditioning unit. With the PEAD series, it is possible to cut energy consumption by controlling not only the air volume but also the compressor capacity.
1. Air volume control by analog input 1-1. Air volume control Indoor air volume can be controlled in 10 different stages from V1 to V10 with analog input 0-10V from the damper system controller supplied on site.

1-4. Example of air volume control 1 Air volume can be selected in the following order. ■ Condition: 1. R1- R4 indicates the air outlet of each indoor unit. 2. R4 fully open at all times. 3. Air volume designed as R1: 5m /min, R2: 5m /min,...
■ Example of system flow The following explains the system flow for duct damper open/close pattern shown in [Fig.1-4-3]. Condition: Voltage decrease from 10.0V to 3.7V when duct damper changes from full-open to R1,R3 close. Damper System Remote Controller R1,R2,R3,R4 full-open operation Damper System Remote Controller R1,R3 On site close...

4. Restrictions Damper system controller setting will be prioritized. Set function on a damper system controller. Also, settings and error codes set by a remote controller will not be reflected to the damper system controller. Signal priority: Damper System remote controller > (analog input) > ME or MA remote controller * Analog input: only air volume control will be effected Function Model...
5. Wiring Conduct electrical wiring in the following order. Wiring must be done with the power OFF. (1) Take off the cover by removing 3 screws from the controller box. A : Screw holding cover (1pc) B : Cover (2) Bore knockout hole for wiring. C : Terminal box D : Knockout hole E : Remove...
