C.2.4. Variant 2
A system with a solid fuel boiler w. manual stoking, one heating circuit, a thermal store and
a hot water storage tank. The BIO MIX Load Unit ensures space and DHW heating and
heat storage in the thermal store. It is recommended to use a Caleon room unit or a room
temperature sensor for a more precise control of the room temperature. To ensure DHW
heating also in periods when the boiler is extinguished, it is recommended to install an electric
heating element fitted with an adjustable thermostat in the hot water storage tank.
Locations of temperature sensors
S1 – lower temperature sensor in a thermal store (shall be ordered separately,
code 9109)
S2 – upper temperature sensor in a thermal store
S3 – temperature sensor in a hot water storage tank
S4 – temperature sensor at the outlet from a solid-fuel boiler
S5 – heating water temperature sensor (in a sheath inside the load unit)
S6 – outdoor temperature sensor
