VALUE
Single outputs can drive the PV in one direction only (e.g.
heat only, cool only, increase humidity etc)
Control Type
Dual outputs can force the PV to increase or decrease
(e.g heat & cool, humidify and dehumidify etc)
Reverse action is typically used with heating applications;
On-Off reverse outputs will turn off when the process
variable exceeds setpoint. Proportional reverse outputs
will decrease the percentage of output as the process
value increases within the proportional band. The
Secondary Output will be direct whenever the Primary
Output is selected as reverse.
Primary Output
Control Action
Direct action is typically used with cooling applications;
On-Off direct outputs will turn on when the process
variable exceeds setpoint. Proportional direct outputs will
increase the percentage of output as the process value
increases within the proportional band. The Secondary
Output will be reverse whenever the Primary Output is
selected as direct.
