Mixer sensor
This function can be used for transferring heat from a solid fuel boiler to a store.
The allocated output 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 difference between the allocated sensors has not fallen below
the switch-off temperature difference
• the temperature at the solid fuel boiler sensor has exceeded the minimum
temperature
• the temperature at the store sensor is below the maximum temperature
• one of the adjusted time frames is active (if the Timer option is selected)
When the set temperature difference is exceeded, pump speed control starts. For
every deviation by 1 / 10 of the adjusted rise value, the pump speed will be adjusted
by 1 %.
If the Target temp. option is activated, the pump speed control logic will change.
The controller will remain at the minimum pump speed until the temperature at the
allocated sensor exceeds the adjusted target temperature.
The Mixer option can be used to keep the boiler return temperature above TMin
boiler. The mixer will be controlled with the adjustable interval.
