Pulses
*When the power is turned on, the valve closing signal of
2200 pulses (Indoor LEV, BC controller LEV1 (G1 type only), and LEV3), or
3200 pulses (BC controller LEV1 (GA1 type only)),
will be output from the indoor board to LEV to fix the valve position.
It must be fixed at point A.
When the valve operates smoothly, no sound from LEV or no vibration
occurs, however, when the pulses change from E to A in the chart or
the valve is locked, a big sound occurs.
*Whether a sound is generated or not can be determined by
holding a screwdriver against it, then placing your ear against the handle.
*1The LEV opening may become greater depending on the operation status.
