Funct. Activation / Deactivation Activated / Deactivated Activated
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 fulfilled:
• the temperature difference between the allocated sensors has exceeded the
switch-on temperature difference
• the temperature difference between the allocated sensors has not fallen below
the switch-off temperature difference
• the temperature at the heat source sensor has exceeded the minimum temperature
• the temperature at the heat sink sensor has fallen below the maximum temperature
• one of the adjusted time frames is active (if the Timer option is selected)
Speed control is deactivated by default. In order to activate speed control, reduce
the minimum pump speed.
When the Set temperature difference is exceeded, pump speed control
starts. If the temperature difference increases by the adjustable Rise value, the
pump speed increases by 10 % respectively.
Note:
For information on timer adjustment see page 10.
