Faults<br />
020 Heat pump fl ow maximum temperature Heat pump fl ow temperature is above the set maximum temperature.<br />
021 Heat pump fl ow minimum temperature Heat pump fl ow temperature is below the set minimum temperature.<br />
022 Low pressure switch The low pressure switch has switched off the heat pump (< 3 times<br />
in 24h).<br />
023 Low pressure lock pressure fault The low pressure switch has switched off the heat pump (> 3 times<br />
in 24h). The heat pump is no longer triggered.<br />
024 High pressure switch The high pressure switch has switched off the heat pump (< 3 times<br />
in 24h).<br />
025 High pressure lock pressure fault The high pressure switch has switched off the heat pump (> 3 times<br />
in 24h). The heat pump is no longer triggered.<br />
