The Solid fuel boiler function can be used for transferring heat from a solid fuel
boiler to a store. 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 solid fuel boiler sensor has exceeded the minimum
temperature
• the temperature at the store sensor has fallen below the maximum temperature
When the Set temperature difference is exceeded, pump speed control starts. For
every deviation of 0.2 K, the pump speed will be adjusted by 1 %.
