5 - 9 Digital Output (DO)
The following is a functional block diagram for digital output (DO).
MV1 processing:
ON/OFF control output, time proportional
output, heating time proportional output
of heating/cooling control
MV2 processing:
Cooling time proportional output of
heating/cooling control
(Parameter bank:
Cy, Cy2, tP.ty)
MV1 and MV2 control output status
When using the default output When using control output When using output assignment
