UFH initial start up

[vala]

Hi all,

So finally got my UFH system fired up and at present mixing valve is set to minimum. I know to steadily increase this every 2-3 days, however what temperature should I set the thermostats to during this phase?

At present they are at the factory default 'reduced' temp of 17° according to Wunda.

They were at 35° (on the thermostats)for a couple of hours after I installed the auto balancing actuators so they could calibrate themselves.

My floor was down about 5 months before UFH came on. I set temp on UFH manifold to 20c ( after checking 20c on the dial was 20c water flow ( you can remove the knob and rotate as reqd) ). I left wall stats at 25c and increased the UFH Mainfold stat by 5c every 36 hours or so until design temp reached. You may find if you have no floor coverings you will need to raise room stats slightly as the UFH will work well on bare floors.

Thanks for the reply. I'll bring up the temp on the stats then as at present they're on the factory default 17°. Manifold flow temp is currently ready 27° and tomorrow it will have been 48hrs since turning on so I'll increase this by 5°.
