Caleffi HIU Electronic Controller SATKF0202

The SATKF0202 is an electronic controller manufactured for the Caleffi HIU range and supplied under the Altecnic part number SATKF0202. It is the control board that manages the operating functions of the SATK20203 heat interface unit. It is a service component, intended for replacement when the existing controller fails or is diagnosed as faulty.

• The heat interface unit has no power or fails to respond when called for heat or hot water
• Fault codes or error indications are displayed that point to the controller
• The unit runs intermittently, cutting in and out without a change in demand
• Controls or settings no longer respond, or the unit reverts to default behaviour
• The controller shows visible signs of damage, moisture ingress or overheating

• Confirm the appliance model is SATK20203 before ordering
• Check the part number printed on the existing controller against SATKF0202
• Verify the fault is with the controller and not with the wiring, sensors or power supply
• Consult the manufacturer's parts list if the appliance model or controller number is unclear
