9.3 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 flow pipe of the underfloor
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.
