Power supply
Standard power supply

400/3/50+N
1. Entering/leaving water temperature user side 30/35°C, external exchanger entering air temperature 7 °C (R.H. = 85%)
2. The overall power absorbed is calculated by adding the power absorbed by the comp the power absorbed by the fans
+ the power absorbed by the auxiliary electrical c the percentage value of the pump to overcome pressure drops inside
the unit
3. COP (EN 14511:2008) performance coefficient in heating mode. Ratio between heating capacity supplied and absorbed
power in accordance with EN 14511:2008. The absorbed power is the sum of the power absorbed by the comp electric
auxiliary c percentage of power absorbed by the pump to prevent pressure drops inside the unit
4. Entering/leaving water temperature user side 40/45°C, external exchanger entering air temperature 7 °C (R.H. = 85%)
5. Entering/leaving water temperature user side 45/55°C, external exchanger entering air temperature 7°C (R.H. = 85%)
6. User side entering/leaving water temperature 23/18°C, external exchanger entering air 35°C
7. EER (EN 14511:2011) performance coefficient in cooling mode. Ratio between cooling capacity provided and power absorbed
in compliance with EN 14511:2011. The absorbed power is the sum of the power absorbed by the comp power
absorbed by the fans + the power absorbed by the electric auxiliary c the percentage value of the pump to overcome
pressure drops inside the unit
8. ESEER calculated by Clivet for radiant systems with water produced at 18°C by taking into account the load conditions and
source water temperature as defined by EUROVENT for water at 7°C
9. User side entering/leaving water temperature 12/7 °C, external exchanger entering air 35°C
10. ESEER calculated by EUROVENT, for systems featuring terminal units with water produced at 7°C
11. PHE = plate exchanger
12. AX = axial fan
13.2 Operating range
Cooling
Twu [°C] = exchanger water outlet temperature
Eat [°C]: external exchanger inlet air temperature
1. Normal operating range
2. Operating range with modulating fans
3. Operating range where the use of ethylene glycol is mandatory in
relation to the temperature of the water at the outlet of the user side
exchanger
4. Operating range with modulating compressor
Heating
Twu [°C] = exchanger water outlet temperature
Eat [°C]: external exchanger inlet air temperature
1. Normal operating range
2. Operating range with modulating compressor
3. Operating range with modulating fans
