Temperature control
with IR floor temperature
sensor
22
During PWM control, the opening and closing time of the valves is calculated
from the temperature difference between the setpoint and the actual value.
The higher this difference, the higher the opening or the closing time.
The optimized actuator control is a specially developed control for thermal
actuators to save energy. At start, the thermal actuator becomes a constant
signal for a defined period. Then, the actuator is controlled with a pulse-
/pause-signal, so less energy is needed.
Each channel has its own control loop. If a wireless room thermostat is ad-
dressed to multiple radio channels, then radio channels are grouped in one
control loop.
The wireless room thermostat with integrated IR floor temperature sensor
measures the room temperature and the floor temperature.
The heating goes on when the set floor temperature or room temperature is
undercut. The set value for the minimum or maximum floor temperature has
highest priority at all times.
The floor temperature measurement ensures that a comfortable floor tempera-
ture is retained.
