Control board replacement

What it is

Heating without proper control swings: scalding one minute, cold the next. Thermostatic mixing valves, digital controllers and sensors hold the delivery temperature steady and protect users against scalding.

What is included

  • Temperature logging before and after
  • Mixing valve or digital controller
  • Sensors and wiring
  • Maximum temperature limiting
  • Operator training

How it works

Diagnose the swing

We log temperature over time to find the real cause of the variation.

Specification

We choose the control strategy: thermostatic mixer, sensor-based controller or recirculation.

Installation

The control is integrated into the existing system with a service bypass.

Calibration

We set the setpoint, cap the maximum temperature and document the configuration.

Frequent questions

Why does my water temperature swing?

The usual causes are pressure imbalance between hot and cold, an undersized appliance and the absence of a thermostatic mixing valve.

Is this useful in a building?

Very. In central systems, controlling delivery temperature is a safety requirement, not a luxury.

Can it be monitored remotely?

In central systems, yes. We implement remote temperature reading and fault alarms.
