*1 Although Simultaneous temperature rise in process (1) is set at the start of the simultaneous temperature rise, Simultaneous
temperature rise not in process (0) is set before the completion of the temperature rise.
• When the mode is changed from the operation mode to the setting mode ('Setting/operation mode
command' (Y1) is turned from ON to OFF) during the simultaneous temperature rise, the control stops. In
addition, 'CH1 Simultaneous temperature rise status' (Un\G414) changes from Simultaneous temperature
rise in process (1) to Simultaneous temperature rise not in process (0). (An error does not occur.)
• When the simultaneous temperature rise function is executed, the setting variation rate limiter cannot be
used.
Conditions to execute the simultaneous temperature rise function
When all of the following conditions are satisfied, the simultaneous temperature rise function can be executed.
• The control is started
• The set value (SV) is larger than the temperature process value (PV).
• "Standard Control" has been selected for "Control mode selection" in "Base Setting" (This function cannot be executed in
the heating-cooling control).
• The simultaneous temperature rise parameter has been determined (or has been set) and a value other than 0 (default
value) has been set.
When a value smaller than 100% is set for the following parameter, temperature rise may not be completed at the same time.
• "Upper limit output limiter" of "Limiter setting" in "Application Setting"
