Functions
Temperature control
RDH100RF/SET offers both 2-position and PID intelligent learning temperature control,
configurable via parameter P01 (control behavior).
2-position control algorithm to switch on and off the heating system within a switching
differential (SD) as per the difference between setpoint setting and measured room
temperature.
PID intelligent learning control algorithm periodically switches on and off the heating system.
The period time (T) and pulse length (P) of the control signal (PWM) are determined by the
setpoint and the measured room temperature.
In general, PID control provides more comfort and is more energy efficient than 2-position
control.
