Valve position setting
reset The parameters V.RS, V.L and V.H are designed for
manual adjustment of valve positions.
Setting V.RS to 1 resets the valve adjustment
settings and causes the indication “V.RS” to blink. 0
Fully-closed valve
position setting Pressing the SET/ENT key with valve position
set to the fully-closed position causes the
adjusted value to be stored. When V.L.
adjustment is complete, V.L. stops blinking.
Pressing the SET/ENT key with valve position
set to the fully-opened position causes the
adjusted value to be stored. When V.H.
adjustment is complete, V.H. stops blinking.

Fully-opened valve
position setting Undefined
Valve traveling time 5 to 300 sec.
Used to operate a valve according to the estimated
valve position. Set the time required for the valve to
open fully from a state of being fully closed. Confirm
the valve traveling time by consulting the datasheet of
the valve’s specifications.
The valve traveling time is only effective when Valve
Adjustment Mode (V.MOD) is set to 1 or 2. 60 sec.
Valve adjusting mode 0: Valve position feedback type
1: Valve position feedback type (moves to the estimating
type if a valve input error or burnout occurs.)
2: Valve position estimating type 0
Automatic valve
adjustment Automatically adjusts the fully-closed and fully-opened
positions of a valve. When this function is used, there is no
need for adjustment using the parameters V.RS, V.L and V.H.
