SFC BOILER / WATER HEATERS - SFC 199
5.2.9 DHW Tank Sensor
The SFC series units allow the use of a tank sensor for controlling the domestic
hot water tank temperature. IBC Indirect water heaters come with a 10KΩ sensor.
An Aquastat can also be used.
If a eld supplied domestic hot water sensor is used, it must be a 10KΩ sensor
matching the following table.
