Product details
AquaCal STK0225 is the retrofit controller service kit for the HP9, supplied with a 60 inch cable. It carries the control board, the display and the sensors together in one kit.
Why it is kitted
Controller faults on a heat pump rarely announce which piece failed. A display that reads nothing, a unit that will not stage, or a temperature that makes no sense can come from the board, the display or a sensor. Replacing the group in one visit is faster than diagnosing down to a single component and ordering twice.
Before ordering
Check that the unit is an HP9 and that a 60 inch cable is the run length you need, since cable length is what separates the kit variants.
