PID HEAT/COOL CONTROL

The controller can manage a heating output and a cooling output in a completely independent manner. Heating and

cooling parameters are described below. Parameters for

PID

(proportional band, integral and derivative time) control are

typically calculated by means of Autotuning and Selftuning functions.

Proportional action

action in which contribution to output is proportional to deviation at input (deviation = difference between controlled variable

and setpoint

Derivative action

action in which contribution to output is proportional to rate of variation input deviation.

Integral action

action in which contribution to output is proportional to integral of time of input deviation.

Control actions

Increasing the proportional band reduces oscillation but increases deviation.

Reducing the proportional band reduces deviation but causes oscillation of the controlled variable (excessively low

proportional band values make the system unstable).

An increase in Derivative Action corresponds to an increase in Derivative Time, reduces deviation, and prevents

oscillation up to a critical Derivative Time value, beyond which deviation increases and there are prolonged oscillations.

An increase in Integral Action corresponds to a decrease in Integral Time, tends to annul deviation between the

controlled variable and the setpoint at rated operating speed.
If the Integral Time value is too long (weak Integral Action), there may be persistent deviation between the controlled variable
and the setpoint.

For more information on control actions, contact GEFRAN.

Proportional, derivative, and integral action

CONTROLS

Control output with only proportional action in case of proportional

heating band separate from cooling band.

Control output with only proportional action in case of proportional

heating band superimposed on cooling band.

Output with separate band

Output with superimposed band

Heat/cool control with separate or superimposed band

This control mode (enabled with parameter Ctr = 14) asks you to specify cooling type. The PID cooling parameters

are then calculated based on heating parameters in the ratio specified (ex: C.ME = 1 (oil), H_Pb = 10, H_dt =1, H_It = 4 im-

plies: C_Pb = 12.5, C_dt = 1 , C_It = 4)

Apply the following values when setting cycle times:

Air

T Cool cycle = 10 sec.

Oil

T Cool cycle = 4 sec.

Water T Cool cycle = 2 sec.
NB.: Cool parameters cannot be changed in this mode.
