4.24 Proportional Band Setting Function
4.24 Proportional Band Setting Function
Proportional band (P) values can be set for heating and cooling separately using this function. Different gradients can
be set by using different proportional band (P) values in a heating and cooling area.
(1) Setting method
(a) For heating
Set the value in CH Heating proportional band (Ph) setting (Un\G35, Un\G67, Un\G99, Un\G131).
( Page 105, Section 3.4.2 (15))
(b) For cooling
Set the value in CH Cooling proportional band (Pc) setting (Un\G720, Un\G736, Un\G752, Un\G768).
