temperature sensors

Temperature sensors for ARTIC and URBAN LINE heat pumps are used for temperature measurement, control, protection and diagnostics within ALPS EXCLUSIVE heat pump systems. These components are intended for installers, service engineers and technical buyers who need to check or replace a sensor accurately.

Always verify the type code, resistance value, cable length, sensor design and connection before installation. This helps prevent incorrect fitting and keeps the heat pump control system operating reliably.

Temperature sensors for ALPS EXCLUSIVE ARTIC and URBAN LINE heat pumps

Temperature sensors are used in compatible ALPS EXCLUSIVE ARTIC and URBAN LINE heat pumps to measure temperature values and transmit them to the controller. Depending on the configuration, these sensors may be used for water-side measurements, outdoor temperature, evaporator temperature, flow and return temperature, domestic hot water control or protection of specific components.

Accurate temperature measurement is important for control behaviour, efficiency, fault diagnosis and safe heat pump operation. The correct spare part depends on the series, unit type, article number, sensor type, measuring range, resistance characteristic, connector, cable length, mounting position and technical configuration.

Important checks for temperature sensors

  • Check whether the temperature sensor is suitable for the relevant ALPS EXCLUSIVE ARTIC or URBAN LINE version.
  • Compare the article number, sensor type, measuring range, cable length, connector, resistance type and mounting position with the original component.
  • Inspect the sensor for cable breakage, damage, moisture ingress, corrosion, loose connectors or abnormal measured values.
  • Look for fault codes, illogical temperature display, cycling behaviour, incorrect switching points or protection functions that are activated without a clear cause.
  • Also check the PCB control, wiring harness, connectors, sensor placement and the technical condition of the circuit in which the sensor is measuring.

Application, replacement and technical attention points

A temperature sensor may need to be replaced when the heat pump registers incorrect values, shows fault codes, does not switch correctly or responds abnormally to temperature changes. Faults can be caused by wear, moisture, cable damage, poor connector contact, contamination around the measuring point or incorrect mounting position.

Work on electrical and refrigeration-related components must be carried out by a qualified technician. After replacement, the measured value, mounting position, connector, cable routing, fault messages, control behaviour and operation of the associated circuit should be checked.

Frequently asked questions about temperature sensors

What is a temperature sensor used for in a heat pump?

A temperature sensor measures temperature values inside or around the heat pump and transmits them to the controller. The heat pump uses these values for control, protection, diagnosis and efficient operation.

When should a temperature sensor be replaced?

Replacement may be required in case of fault codes, illogical temperature values, cable breakage, damaged connectors, moisture ingress, corrosion or when the heat pump no longer responds correctly to temperature changes.

Does every temperature sensor fit every ALPS EXCLUSIVE heat pump?

No, temperature sensors differ by series, unit type and technical configuration. Always check the article number, sensor type, measuring range, resistance characteristic, connection, cable length and mounting position.

Can a fault code also be caused by wiring?

Yes, a fault code may appear to be caused by a defective sensor while the actual cause is cable breakage, a loose connector, moisture, PCB control or incorrect mounting position. The complete measuring circuit must therefore be checked.

Can a temperature sensor be installed by the end user?

For safe and correct operation, installation should be carried out by a qualified technician. Measured value verification, connection, sensor placement and system diagnosis must be technically checked.
