8.5. Control of Heating-cooling Type
For the heating-cooling control, one of the outputs out1...out4
should be set to y, one of the outputs out1...out4 should be set
to Cool and the displacement zone Hn for cooling should be configured.
For the heating loop, the PID parameters should be configured:
pb, t, td, for the cooling loop the PID parameters: pbC, tiC, tdC.
The parameter pbC is defined as the ratio of the pb parameter from
the range 0.1...200.0 %.
The pulse period for logic outputs (relay, SSR) is set independently for the heating and cooling loops (depending on the output,
these are to1...to4).
If there is the need to use the PID control in one loop
and the ON-OFF control in the other loop, one output should be set
to PID control and the other one upper relative alarm.
