What it is
The Danfoss HSA3 is a 3-port valve actuator from Danfoss's H Series, part number 087N658700. It is the motor unit that drives a 3-port valve, switching the flow between heating, hot water, or both as called for by the system controls, and is designed for use with Danfoss HSV3 valve bodies.
Signs this part needs replacing
- Valve fails to switch between heating and hot water positions
- Motor hums or runs but the valve head does not move
- No power reaching the actuator despite a live feed at the terminals
- Actuator overheats or gives off a burning smell
- System calls for heat but one or both circuits stay cold
Before you order
- Check the part number stamped on the existing actuator matches 087N658700 before fitting
- Isolate electrical power to the valve before disconnecting wiring
- Confirm the actuator detaches from the valve body without draining the system, but check for any residual pressure first
- A Gas Safe registered engineer should carry out any work involving the boiler or its controls
