on/o control in heating mode:
On/o with PWM control is an algorithm that reduces
the e ects of hysteresis around the set point value
by adjusting the controls on the values ranging from
0% to 100% where 0% means “control o ” and 100%
means “maximum control action”.
Once a cycle time is de ned the thermostat sets the
actuator to ON for a fraction of the cycle time and OFF
for the remaining part. Driving the actuator with the
control value of 80% means that it is active (i.e., ON)
for 80% of cycle time and OFF for the remaining 20%.

KNX PARAMETER SETTINGS
Cycle time (TCp)
Proportional band (Bp)
10, 20, 30, 60 min
It de nes the time interval.
The proportional band BP is a range of temperatures
between “Setpoint” and “Setpoint-Bp” in heating mode and
between “Setpoint” and “Setpoint+Bp” in cooling mode, wi-
thin this interval thermostat controls the temperature using
the proportional algorithm; outside It drives actuator always
in ON or OFF.
When temperature is inside this range device wait the end of
the cycle time before calculating the duty cycle of the next
cycle.
When temperature is outside of this range : below “Setpoint-
Bp” in heating mode or above “Setpoint+Bp” in cooling mode
it starts a new cycle as soon as temperature enters the Bp
