(c) Enabling the setting
Enable the setting contents by either of the following.
• Turning off and on Initial data setting request flag (RY9) while the operations of all channels are stopped
• Turning off and on During operation setting change instruction (RY10)
(d) Default value
A default value differs depending on modules to be used.

Heating-cooling
Set the pulse cycle (ON/OFF cycle) of the transistor output. In the heating-cooling control, the output cycle of the
heating control and cooling control can be set individually. 10CH, 13CH, 16CH, and 19CH are used for heating in
the heating-cooling control.
The ON time of the control output cycle is determined by multiplying the control output cycle by the manipulated
*1
value (MV)
(%) calculated by PID operation. If the manipulated value (MV)
cycle is output repeatedly.
*1
For the heating control output cycle, the manipulated value for heating (MVh) is used. For the cooling control output
cycle, manipulated value for cooling (MVc) is used.

Ex.
CH Control output cycle setting (address: 10CH, 13CH, 16CH, 19CH)
The following calculation shows that the transistor output turns on for 70s and off for 30s per 100s.
