Special functions
6.5.8. - Difference
6.5.8.3. - ∆ T difference
6.5.8.5. - DF source (sensor)
The relay is switched on when a specic temperature difference (∆ T) is
reached.
Switch on - difference:
When this temperature difference is reached, the relay is switched on.
Switch off - difference:
When this temperature difference is reached, the relay is switched off.
Heat source sensor for Difference function
This determines the sensor for the heat source.
6.5.8.2. - Diff Tmin
Minimum temperature at source sensor to enable the difference relay
When the temperature at the source sensor is below this level, the difference
function is disabled.
6.5.8.6. - DF Drain (sensor)
6.5.8.4. - DF Tmax
Drain sensor / Target sensor for difference function
This determines the sensor for the target storage.
Maximum temperature at target sensor to enable difference function
If the temperature at the target sensor exceeds this value, difference function is
disabled.
