Setting Control Specifications Section 4-3
■ MV at Stop
This parameter sets the MV when control is stopped.
For heating/cooling control, the MV at Stop parameter applies to the cooling
side if the MV is negative and to the heating side if the MV is positive.
The default is 0.0, so an MV will not be output for either standard or heating/
cooling control with the default setting.
The order of priority is as follows: Manual MV > MV at Stop > MV at PV
Error.
■ MV at PV Error
This parameter sets the MV when an input error or remote SP input error
occurs.
The order of priority is as follows: Manual MV > MV at Stop > MV at PV
Error.
■ MV Limiter
This function limits the MV output by applying upper and lower limits to the
calculated MV.
• The following MVs take priority over the MV limits.
•Manual MV
•MV at Stop
• MV at PV Error
• For heating/cooling control, upper and lower limits are set on overall heat-
ing/cooling control.
(They cannot be set separately for heating and cooling.)
