Setting of heating and cooling control PID control mode
Press and hold for
more than 3 seconds
Selecting Output Operation (REV, DIR, DUAL)
REV : Heating control
DIR : Cooling control
Dual : Heating and cooling control
Use or , key to adjust the setting number corresponding to the output type, and then save it
using key.
※ Caution!
In Heating & cooling mode, control output uses alarm 2
output, so must be change to alarm 1 or alarm 3 when
using alarms.
Cycle time in heating (output 1) SSR or relay
※ It is not used in the SCR (4 to 20 mA) mode,
so it will not be displayed.
Cycle time in Cooling (output 2) SSR or relay
※ It is not used in the SCR (4 to 20 mA) mode,
so it will not be displayed.
The cooling gain setting range can be set from 0.1 to 10.0
※ Explanation of operation according to dead band value
The default value is set to 0.0% and does not need to be
set except in special cases.
