Danfoss Link™ HC/RS floor heating system
Your oor heating system consists of three
main components:
- Manifolds (typically located in a utility
cabinet) distribute heat to the individual
rooms and back.
- The master controller turns the heat on
and o at the individual valves feeding the
rooms.
- Room sensors measure the room tempe-
rature and can be used to set the desired
room temperature.
How does floor heating work?
The principle of oor heating is to heat the
room from below, which is an exceptionally
comfortable heating method.
Floor heating pipes can be embedded directly
into the concrete slab (heavy/wet oor heat-
ing), or special heat distribution panels can
be used (e.g. SpeedUp) located closer to the
nished oor (light/dry oor heating).
Please note: Up to 95% of all systems are installed as heavy
oor heating. Contact your installer if you are
in doubt as to whether your system has been
installed as heavy or light oor heating.
Heavy oor heating has a relatively long re-
sponse time. It will generally take about 1-2
hours per adjusted degree for the system to
reach the desired room temperature.
On very few days in the year, typically during
transitional periods, temperatures slightly over
or under those set must be expected. This oc-
curs when the weather changes faster than the
controller is able to keep up, e.g. in the event of
sudden periods of intense sunlight or sudden,
signicant drops in temperature.
Light oor heating has a relatively short re-
sponse time. It will generally take about 20
minutes for the system to achieve the desired
room temperature for each adjusted degree.
