Time modulating ON/OFF control
This type of control can be selected if the cooling capacity is large and the cooling system is suitable for
modulating control.
Cooling is
continually
on, if the temperature of the cooling control is higher than
Se hysteresis
.
Cooling is
continually
off, if the temperature is equal to or lower than the
Setpoint
.
Cooling 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 cooling control
Inside
Hysteresis
the control computer controls the cooling for a part of the
Repeat time
. The control
computer calculates this on/off time as follows:
Setpoint:
27.0°C
Measured house temperature:
28.5°C
Hysteresis:
3.0°C
Repeat time:
100 sec.
The cooling relay will repeatedly be on for 50 seconds and off for 50 seconds.
The humidity control can only activate if a humidity setpoint has been set. Enter to which relay the humidity
control has been assigned. Also enter the type of relay control:
ON/OFF
or
MODULATING
.
See also Settings humidity.
The control computer has two types of humidity control:
1.
ON/OFF control
Humidifying activates as soon as humidity in the house drops
below
Setpoint humidity
– hysteresis
.
Humidity deactivates when the measured house humidity is equal
to or higher than
Setpoint
humidity
.
A
Repeat time
can be used to avoid unnecessary
activation/deactivation of the humidity. When the humidity
activates, it will remain on for at least the
Repeat time
. When the
humidity deactivates, it will remain off for a minimum of this time.
2.
Time modulating ON/OFF control
The humidity is
continually
on, when the measured house humidity is lower than
Setpoint
– hysteresis
.
The humidity is
continually
off, when the house humidity is equal to or higher than
Setpoint.
Humidity is
Modulating
on, if the humidity is in the
Hysteresis
. The control computer calculates the
modulation time based on the
Repeat time
.
