Electrical Installation - Weider BWP 270 0A Mode D'emploi Et D'installation

The desired set point temperature for DHW can be adjusted by the user in the parameter menu in between 5°C and the
installation specific maximum temperature Tmax (installer setting).
Tmin is the set point for supplementary heating. It can be adjusted independently of the DHW set point. The factory
setting for DHW set point "SETPOINT" is 55°C and for "Tmin" 35°C.
The set point temperature can be achieved either by the HP (energy source selection "HP", "HP + EL", "HP + boil") or the
supplementary heating (energy source selection "EL", "boil"), depending on the choice of the energy source. Tmin is
achieved with heat pump and supplementary heating (energy source selection "HP + EL", "HP + boil"), if selected.
The heat pump operates with a hysteresis of +1 -3 °C around the DHW set point. The supplementary heating operates
with a hysteresis of + -1 °C.
The DHW HP is equipped with a permanent and an automatic defrosting system. This reduces the need for defrosting
and increases efficiency (increased operation cycle). Nevertheless it is normal, that (especially at low temperatures and in
heavy-duty operation) he evaporator has to undergo a de-icing procedure. When the evaporator temperature gets too
low the heat pump will stop and the defrosting procedure starts automatically. For air defrosting this limit is -8 °C, for
hot-gas defrosting -18 °C. Normal operation resumes at an evaporator temperature of +5 °C.
The LED indicators 29 and 30 of the control panel show the actual operation mode, the upper LED(29) for the heat
pump and the lower LED (30) for supplementary heating:
•
Off: Inactive (not selected)
•
Orange: Selected, but running standby mode
•
Green: Selected and producing DHW

ELECTRICAL INSTALLATION:

The heat pump is equipped with a 2 metre power supply cord, 3 x 1.5 mm
with stress relief and a safety plug.. The socked should be protected individually by an automatic circuit breaker and a
residual-current circuit breaker (30mA)
Max. power input: see "page 4 - technical data".
Power supply_ 230V AC single-phase, 50Hz
Mains lead colours: phase – brown, neutral – blue, earth – yellow/green
NOTE: The appliance must be installed in accordance with national wiring regulations by a qualified and authorized
installer. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified
personnel in order to avoid a hazard.
