Make the best use of nature’s energy (air,
water, earth) to heat or cool (reversible
system) a heating circuit or a hot water
system in either an industrial, domestic or
commercial setting.
The choice of solution may be
determined by fi nancial considerations
(energy costs).
system: Heat pump
Control of heating and hot water
Heat pump control.
Dedicated product application
How the application works:
The heat from the warm fl uid (air blown by a fan, or water
provided by a heat-exchanging source or coolant) is captured by
a refrigerating liquid which is compressed to give it a pressure
of 40 bar and a temperature 140°C. In a heat exchanger, this
refrigerating liquid then transfers its heat to water (cold source)
for a hot water system (underfl oor heating) or a hot water tank
(water for a hot water system or swimming pool).
Once this thermal exchange has taken place, the fl uid which
has lost both temperature and pressure has its pressure further
reduced by a solenoid valve which drastically reduces its
temperature even more.
This fl uid is then able to receive the heat from the hot source,
and the cycle is ready to begin again.

Millenium 3 logic controller.
Millenium 3 accessories:
- NTC: temperature (°C) probe – probe providing resistance as
a function of the temperature. Connects directly to the analogue
inputs (0-10 V). A dedicated function block enables resistance to
be converted into temperature.
- Pt100: temperature probe with a converter on the analogue
inputs or directly linked to extensions XA03, XA04W.
Compressor start-up control/anti-short cycle.
User-friendly software and ease of programming.
Front-panel parameter setting for temperature instructions.
Functions include clock, vacations, frost protection.
Full/half-load function.
Analogue inputs: NTC probes.
Adaptations possible (development of “water law” or “heating
curve” functions).
