Instructions for use ecoTEC

4.10 Frost 

protection

The frost protection feature only protects the boiler. Any 
other parts of the system liable to frost damage should 
be protected accordingly.

 Caution

The frost protection and monitoring systems 
are only active when the main ON/OFF control 
of the appliance is in the “I” position and it is 
not disconnected from the main power supply.

Frost protection function

The boiler has a frost protection function.
If the heating flow temperature falls below 5 °C with the 
main ON/OFF control turned on, the appliance starts up 
and heats the boiler to 30 °C.

 Caution

Parts of the system may freeze.
The frost protection function cannot guarantee 
that water flows through the entire heating sys-
tem.

Maintenance and customer service

Inspection and maintenance

Permanent operational readiness, reliability and a long 
service life require inspections and maintenance work to 
be regularly carried out by a heating engineer or 
Vaillant.
For further details please contact Vaillant Service 
Solutions: (0870 6060777). 

 Danger

Risk of injury and damage due to improper 
handling
Never attempt to perform maintenance or 
repairs on the appliance yourself.
Have a specialist heating company do the work. 
We recommend signing a service agreement.
The reliability of the appliance can be impaired, 
resulting in damage to property or personal 
injury if maintenance work is not carried out.

Regular servicing ensures maximum efficiency and eco-
nomical operation of your gas wall heater.
