Funct. Activation / Deactivation Activated, Deactivated Deactivated
The Heat exchange function can be used for transferring heat from a heat source
to a heat sink.
The allocated relay is energised when all switch-on conditions are fulfi lled:
• the temperature difference between the allocated sensors has exceeded the
switch-on temperature difference
• the temperature at the heat source sensor has exceeded the minimum tem-
perature
• the temperature at the heat sink sensor has fallen below the maximum tem-
perature
When the Set temperature difference is exceeded, pump speed control starts.
For every deviation of 2 K, the pump speed will be adjusted by 10 %.
When the Timer option is activated, a timer is indicated in which time frames for
the function can be adjusted.
Note:
For more information about timer adjustment, see page 11.
