Room factor < 10
If the room factor is < 10, the controller will calculate the set flow temperature
using the heating system Curve plus the room influence:
Set flow temperature = set tempe remote c day correction or
night corr room influence.
Room factor = 10
If the room factor is equal to 10, the controller will calculate the set flow temper-
ature by means of the room influence, the outdoor temperature will not be taken
into account.
An outdoor temperature sensor cannot be allocated. The parameters Day / Night
correction, Timer and TSummer will not be indicated.
The start value of the set flow temperature can be influenced by the parameter
Heating curve. The start value corresponds to the set flow value of the selected
curve at an outdoor temperature of 0 °C.
Set flow temperature = set flow start value + room influence
In order to calculate the deviation of the room temperature from the adjusted
set value, a room thermostat is required. The adjustments can be made using the
parameter RTH(1 … 5). RTH1 is always pre-adjusted for the room influence with
a room factor < 10.
Room control
For the Room control with room factor = 10, the adjustment of all room ther-
mostats activated will be considered. The controller will calculate the average
value of the deviations measured.
Room thermostat option
In order to integrate room thermostats into the control logic without activating
the room influence option, proceed as follows:
With the Room thermostat option, up to 5 room thermostats can be integrat-
ed into the control logic.
To each room thermostat, a sensor input can be allocated. The temperature at the
allocated sensor is monitored. If the measured temperature exceeds the adjusted
value TambSet at all activated room thermostats and if the parameter HC off is
activated, the heating circuit will switch off.
Common room thermostats with potential-free outputs can be used alternatively.
In this case, Switch must be selected in the Type channel. The corresponding
input must beforehand be set to Switch in the Inputs / Outputs menu. Only inputs
set to Switch will be displayed in the channel Sen. RTH as possible inputs for a
Switch type room thermostat.
When the Timer option is activated, a timer is indicated in which time frames
for the function can be adjusted. During these time frames, the adjusted room
temperature decreases by the Correction value.
Note:
For information on timer adjustment see page 10.
