the flow temperature exceeds a certain value, established by the

manufacturer depending on the heat pump type (see the heat pump

service manual).

Max.return t. (°C)

.......

Max. heat pump return temperature. When this temperature is

exceeded, the heat pump is switched off. The heat pump will also

switch off when the return temperature exceeds a certain value,

established by the manufacturer depending on the heat pump type

(see the heat pump service manual).

Min.outd.t. (°C)

..........

Min. outdoor temperature for heat pump operation. When the

temperature drops below this value, the heat pump is switched off. The

heat pump will also switch off when the outdoor temperature drops

below a certain value, established by the manufacturer depending on

the heat pump type (see the heat pump service manual).

Max.outd.t (°C)

.......... Max. outdoor temperature. When the outdoor temperature exceeds

this value, the heat pump is switched off.

Max.brine.t. (°C)

........ Max. brine circuit temperature. When the brine temperature exceeds

this value, the heat pump is switched off. Applies to ground-coupled

heat pumps only.

Restart time (min)

...... Min. delay between two heat pump starts.

Min.run.time (min)

.................................... Minimum time of HP operation. It is activated either after compressor

start, or after DHW heating is finished (if the heating circuit demand is

higher than 10°C), or after a defrosting cycle is finished.

Return t. (°C)

.............. HP return temperature

Hot gas (°C)

................ HP compressor hot gas temp.

Flow temp. (°C)

.......... HP flow temperature

Cond.temp. (°C)

......... HP condensing temp.

Cond.press. (bar)

....... HP condensation pressure

Evapor.1 t. (°C)

........... Temperature of discharged air/incoming brine circuit

Evapor.2 t. (°C)
