What it is

The SATKF0004 is a stepper motor actuator kit manufactured for Caleffi HIU products. It drives the valve position on the heat interface unit in response to the control signal, allowing the unit to modulate flow as demand changes. The kit is supplied as an actuator with its retaining clip.

Signs this part needs replacing

  • The HIU does not respond when there is a call for heat or hot water
  • The actuator runs continuously or hunts without settling at a stable position
  • The valve position does not change despite a correct control signal
  • The motor is noisy, judders, or feels hot in operation
  • The actuator body, wiring or connector shows signs of damage or water ingress

Before you order

  • Confirm your appliance is a Caleffi HIU product and check the model against the manufacturer's parts list
  • Check the existing actuator part number and connector type match SATKF0004
  • Confirm the retaining clip is present and undamaged on the valve body before fitting
  • Isolate the electrical supply to the HIU before removing or fitting the actuator
