Section 11: Technical specification of the LA MI range

Component

Notes

Water Pump

Circulates water around the heating circuit.

Pressure Gauge

Gives the pressure of the water in the heating circuit.

Flow Switch

Checks the water flow in the heating circuit for efficient and safe operation.

Pressure relief valve

A safety device that relieves the pressure in the heating circuit if it exceeds
3 bar.

Inline flow boiler

Additional heating capacity for Bivalent operation.

OLP (Over load protection)

A safety device to prevent the inline flow boiler from overheating the
heating circuit.

Sledge

Two metal rails increase the structural integrity of the heat pump
