• Due to air flow limitations, RHP units with recirculation function (figure 2) working regime could be
unstable. If one of air flow (in recirculation function exhaust on fan side) are lower than in figure 1,
heat pump capacity will be limited or heat pump will be switched off;

• Maximum outside temperature for heating is 15 °C and minimum outside air temperature for cool-
ing is 20 °C. If outside air temperature exceed this limits heat pump will be switched off and indica-
tion icon will occur in control panel (more detail in page 32);
• When exhaust air temperature after rotary heat exchanger are <(-10) °C, heat pump will be switched
off and indication icon will occur in control panel (more detail in page 32);
• Heat pump has pressure switches for safety. High pressure cut out – 42 bar, cut in – 33 bar. Low pres-
sure cut out – 1.7 bar, cut in – 2.7 bar;
