Setting of the sensor thermal control alarm:
No alarm
With outside temp: the controller calculates the maximum difference alarm,
taking a high outside temperature into account.
Without outside temp: the controller calculates the maximum difference alarm,
not taking a high outside temperature into account.
Outside temperature
influence
Setting of the outside temperature influence:
No influence
Bandwidth only low temp: influence low outside temperature on bandwith.
Bandwidth only high temp: influence high outside temperature on bandwith.
Bandwidth low & high temp: influence low and high outside temperature on
bandwith.
StartT vent. only high temp: influence high outside temperature on start
temperature ventilation.
StartT vent. high & bandw low: influence low outside temperature on bandwidth
and influence high outside temperature on start temperature ventilation.
Low outside temp
On cold days (low outside temperature) the bandwidth can be influenced; ventilation
is increased less rapidly as soon as the temperature becomes higher than Start
temperature ventilation. If the outside temperature is 5°C lower than Start
temperature ventilation, the controller will increase the bandwidth by 0.1°C for each
degree Celsius that it is colder.
High outside temp
On hot days the high outside temperature can influence the bandwidth or start
temperature ventilation. The temperature control between the day/night period is
more gradual.
If a high outside temperature influence on start temperature ventilation is chosen,
Setpoint heating will also be influenced. If thermal control has been assigned to the
same sensor as the ventilation control, Setpoint thermal control will also be influenced
by a high outside temperature.
If the outside temperature becomes higher than Start temperature ventilation and
ventilation is maximum the controller will increase the bandwidth by 0.1°C every 5
minutes. When the outside temperature drops below the set Start temperature
ventilation, the controller will decrease the extra bandwidth or start temperature
ventilation increase.
Decrease time OT
influence [h]
Setting of the time (hours) within which the controller must decrease the influence
caused by a high outside temperature.
If the outside temperature influence on start temperature ventilation and
setpoint heating has been set, this decrease time must be set to a period
longer than 24 hours. The decrease time will not start in the first 24
hours; during this period another hot day may occur. However, if the
weather remains cooler, the computer will start the decrease during the
number of hours after the first 24-hour period. For example, if a decrease
time of 32 has been set, the required normal temperature will be reached
after 32-24 = 8 hours + 24 hours (1 day).
