BFM #44 (CH1) and BFM #63 (CH2): Setting change ratio limiter
In BFM #44, set the setting change ratio limiter of CH1. In BFM #63, set the setting change
ratio limiter of CH2.
The setting change ratio limiter function changes step by step the difference in the temperature
set value when the temperature set value is changed.
Set the variation (%) per minute.
The allowable set range is from 0.1 to 100.0%.
When BFM #44/#63 is set to "0", the setting change ratio limiter function is disabled and the
set value immediately changes.
Example
When the temperature set value 1 (SV1) is changed to the temperature set value 2 (SV2)
(When the set value is changed to a larger value)

changing to the SV step by step.
