Electrical Installation - Breeze VT3130 Installation And Operation Manual

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:

2
The heat pump is equipped with a 2 metre power supply cord, 3 x 1.5 mm , which comes out on the back of the device 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.
