11.6 Installer instructions
To determine if a problem is caused by the supply system or the control system, loosen the actuators from the manifold for the room 
concerned, wait a few minutes and check if the fl ow pipe of the fl oor heating loop becomes warm.
If the pipe does not become warm, the problem is in the heating system. If the loop becomes warm, the cause could be the room control 
system.
A supply system defect can be indicated by no warm water in the manifold. Check the boiler and circulation pump.
The products in this document might not be compatible with older versions of the Uponor Control System.
