MV1/MV2 process
The time proportional cycle and time proportional cycle mode of MV1/MV2 can
be set.
• MV1 is the general term for the ON/OFF control output, time proportional
output, and time proportional output for heat side of the Heat/Cool control.
MV2 is the time proportional output for cool side of the Heat/Cool control.
• When MV1 is connected only to the voltage pulse output in the DO Assignment,
the display and setting of the time proportional unit 1 (CyU) can be performed.
• When MV1 is connected to any of the relay control output, voltage pulse control
output, and event output in the DO Assignment, the display and setting of the
time proportional cycle 1 (Cy) can be made. However, when the time
proportional unit 1 (CyU) is other than “0”, the display and setting of the time
proportional cycle 1 (Cy) cannot be performed.
• When the Heat/Cool control is used and MV2 is connected only to the voltage
pulse output in the DO Assignment, the display and setting of the time
proportional unit 2 (CyU2) can be performed.
• When the Heat/Cool control is used and MV2 is connected to any of the relay
control output, voltage pulse control output, and event output in the DO
Assignment, the display and setting of the time proportional cycle 2 (Cy2) can be
made. However, when the time proportional unit 2 (CyU2) is other than “0”, the
display and setting of the time proportional cycle 2 (Cy2) cannot be performed.
• The initial value of the time proportional cycle 1 (Cy) is “10” when the control
output 1 is the relay output and it is “2” in other cases.
• The initial value of the time proportional cycle 2 (Cy2) is “10” when a model
with one control output point is used and it is “2” when other models are used.
