5.4.16.2 INFLUENCE FUNCTIONS
1. Influence cooling on maximum ventilation:
If the COOLING PARAMETERS PAGE CONTROL
parameter is ON/OFF and COOLING OUTPUT is
ON then Max. Vent value is equal to
INFLUENCE 1 PAGE MAX. VENT. COOL
parameter.
If the INFLUENCE 1 PAGE MAX. VENT. COOL parameter
is NON or COOLING OUTPUT is OFF then Max. Vent
value is defined in NOTE2.
Outside Temp. [°C] (NOTE2)
Min.Vent [%]
NOTE1:
If VENTIL. PARAMETERS PAGE SENSOR parameter is ROOM1;
Max. Inf. = Min.Vent * INFLUENCE 1 PAGE T.L.O.T/MN.VNT,
If VENTIL. PARAMETERS PAGE SENSOR parameter is ROOM2;
Max. Inf. = (any offset parameter from A(NOTE3) to H(NOTE3)) * INFLUENCE 1 PAGE T.L.O.T/T.OFF,
Influence factor high outside temperature on temperature offset;
Max. Inf. = (any offset parameter from A(NOTE3) to H(NOTE3)) * INFLUENCE 2 PAGE T.O.TMP OFFS.
NOTE2:
If curve is enabled;
Settemp= HOUSE TEMP from curve; Min.Vent= MIN. VENT from curve; Max.Vent=MAX. VENT from curve,
If curve is disabled;
Settemp= SET VALUES PAGE TEMP.HOUSE.
Min.Vent= SET VALUES PAGE VENT. MIN.
Max.Vent= SET VALUES PAGE VENT. MAX.
NOTE3:
A = Settemp(NOTE2) + SET VENTILATION PAGE VENTILATION1.
B = Settemp(NOTE2) + SET VENTILATION PAGE VENTILATION2.
C = Settemp(NOTE2) + SET VENTILATION PAGE VENTILATION3.
D = Settemp(NOTE2) + SET VENTILATION PAGE VENTILATION4.
E = Settemp(NOTE2) + SET VENTILATION PAGE VENTILATION5.
F = Settemp(NOTE2) + SET VENTILATION PAGE VENTILATION6.
G = Settemp(NOTE2) + SET VENTILATION PAGE VENTILATION7.
H = Settemp(NOTE2) + SET VENTILATION PAGE VENTILATION8.
2. Influence low outside temperature on minimum ventilation
If outside temperature lower than inside to avoid draughts, minimum ventilation is depended on
INFLUENCE 1 PAGE F.L.O.T/MN.VNT and INFLUENCE 1 PAGE T.L.O.T/MN.VNT parameters.
The influence starts 5 °C below the settemp.
