Explanation control functions
The control computer activates heating if the house
temperature drops below Setpoint – hysteresis. If the
house temperature rises, the heating will stay on until the
control value heating is reached.
A set Repeat time can be used to prevent unnecessary
activation/deactivation of the heating. When the heating
activates, it will remain on for at least the Repeat time.
When the heating deactivates, it will remain off for a
minimum of this time.
The heating is continuously on, if the temperature of the heating control is lower than Setpoint – hysteresis.
The heating is continuously off, if the temperature is equal to or higher than the Setpoint.
Heating is modulating on, if the temperature is in the Hysteresis. The control computer calculates the modulation
time based on the Repeat time.
Example: Time modulating heating control
Inside Hysteresis the control computer controls heating during a part of the Repeat time. The control
computer calculates this on/off time as follows:
Setpoint: 20.0 °C
Measured house temperature: 19.6 °C
Hysteresis: 1.0 °C
Repeat time: 100 sec.
The heating relay will repeatedly be on for 40 seconds and off for 60 seconds.
