PID Cascade
If temperature of heating element is measured, it is possible to increase stability of the heating system using two PID Smart Rules linked together (a.k.a. PID cascade).
Comparison with simple hysteresis regulation:
PID Cascade | Hysteresis |
|---|---|
(/) smooth continuous regulation (X) slow start | (/) fast start (X) oscillating regulation |
Example of using PID cascade in regulation of floor heating, measuring both - under-floor and ambient room temperature.
Parameter | Zone PID Smart Rule | Floor PID Smart Rule |
|---|---|---|
Output actuator | Thermostat for heating element | Switch (relay) |
Limit temperature | Optional: By default is set to 10 ºC - 30 ºC. | Optional: Floor temperature sensor |
Max. floor temperature allowed by hygienic standards is 28 ºC, however for heating purposes it is possible to use a few degrees higher temperature (e.g. 36 ºC), because temperature sensor is measuring temperature below surface.
