Existing controller

This controller
is at end of life.

Renovating a heating plant.

Replace it
without touching
the hydraulics.

Heat exchanger, heating circuits and cylinders stay in place.

The solution: WS-SMART-HG

One more circuit,
one more module.

WS-Smart-IO modules daisy-chain from box to box: one bus cable, one 230 V cable.

Wellset · Sion · wellset.ch

The wiring
gets shorter.

Each module sits next to the device it controls.
No more cable bundles, circuit by circuit.

Setpoint Y7.0 V
Actual position U2.0 V
Valve override detected

A valve forced
by hand shows up.

The actuator reports its actual position. The controller compares it with its setpoint.

Detection from 0.2 A
Circulator pump stopped

So does a pump
that has stopped.

The output that enables the pump measures its current, from 0 to 10 A.
