Outdoor temp control of exchanger
Instead of using Exchanger AO for analogue control of the heat exchanger it
can be set to run on-off against outdoor temperature. The function controls a
digital output “Outdoor controlled exchanger”, which is activated when the
outdoor temperature falls below a set value.
Rotating exchanger
Control
Rotational speed is controlled by the analogue signal ”Exchanger”. A rotatry
controller alarm feedback can be connected to the digital input ” Rotary exchanger
alarm”. An alarm is generated if this input is activated.
Function to prevent the heat exchanger from frost:
A temperature sensor, exhaust air, outdoor air or extra controller sensor can be
used as a prevention sensor. It is possible to set a starting temperature. This
represents both the minimum time that the function should be active, the supply air
fan and extract air fan compensation, as well as the minimum time before the next
prevention cycle should begin. While the cycle is active, ”Defrosting” is shown in
the NaviPad.
Plate exchanger
Control
The airflow through the exchanger is controlled by a shut-off damper and a by-
pass damper. Both dampers are controlled by the same analogue output
”Exchanger”.
