10 - 1 Static Pressure Drop Unit
HXHD-A
3TW60669-1
unit ESP without DHW 3way valve
unit ESP including DHW 3way valve
Note:
In case of stand alone tank, available ESP during DHW mode: to be confi rmed
1. The ESP curves are the maximum ESP curve for different
¨
T types (pump rpm = 4400
¨
T = 5°C; pump rpm = 4000 for
¨
T = 10°C).
The pump of the indoor module is inverter controlled and controls to have a fi xed
¨
T between return and leaving water temperature.
2. In case of installing a demestic hot water tank there is an additional pressure drop over the three way valve (delivered as accessory with the tank).
ESP: external static pressure
Flow: waterflow through the unit
Warning:
1. Selecting a flow outside the curve can cause damage to or malfunction of the unit. See also minimum and maximum allowed water fl owrange
in the technical specifi cations.
2. Water quality must be according to EN directive EC 98/83 EC.
