6.2.1.3 Heating and Cooling Control

Heating and cooling control mode: heating and cooling with a single temperature
controller when it is difficult to control subject temperature with only heating or cooling.

Heating and cooling control mode controls the object using different PID time
constants for each heating and cooling. It is also possible to set heating and cooling
control in both PID control or ON/OFF control mode. Heating/cooling output can be
selected among Relay output, SSR drive voltage output and current output depending
on model types choosen according to your application environment. (Note that only
standard SSR control is available for SSR drive output in OUT2.)

For heating/cooling control, each output for heating and cooling is automatically
allocated as described in the following table.
