Troubleshooting

Malfunction

Possible reasons

Recommended action

The temperature exceeds the

temperature adjusted at the control

thermostat.

Control thermostat defective

Replace the control thermostat.

Foreign particles blocking the valve

plug

Remove foreign particles.

Replace damaged parts.

Valve trim is worn out.

Replace damaged parts.

Valve too large for control task

Check the sizing.

Sensor is installed incorrectly.

Check the installation of the control

thermostat (see section 5.2.2).

The temperature is below the

temperature adjusted at the control

thermostat.

Insufficient heating energy available

Draw up an energy balance.

Strainer blocked

Drain and clean filter of the

strainer.

The valve is not installed in the

direction indicated by the arrow.

Remove the valve and install it

again in the direction indicated by

the arrow.

A safety device (e.g. STL etc.) has

been triggered.

Check plant. Unlock safety device

or replace it.

Valve too small for control task

Check the sizing.

The valve is jammed.

Replace both seat and plug if one

of them is damaged or order a

new valve.

Hydraulic controller jammed.

Replace the hydraulic controller.

The temperature (adjusted at the

control thermostat) varies.

Valve too large for control task

Check the sizing.

The valve is not installed in the

direction indicated by the arrow.

Remove the valve and install it

again in the direction indicated by

the arrow.

Sensor is installed incorrectly.

Check the installation of the control

thermostat (see section 5.2.2).

Increased friction, e.g. due to

foreign particles between seat and

plug or in the stem guide on the

bonnet.

Remove foreign particles.

Replace damaged parts.

Leakage at the connection between

the hydraulic controller and valve or

control thermostat.

Seal is defective

Replace damaged parts.
