Cover loss: Conditions Winter Indoor 20ºC 50% RH Outdoor -20ºC 94% RH 9mm NBR (std) 1790 W 2.0% HC 50mm rock wool 437 W 0.4% HC Conditions Summer Indoor 27ºC 50% RH Outdoor 35ºC 40% RH 9mm NBR (std) 615 W 1.00% TCC 50mm rock wool 151 W 0.24% TCC AIR TREATMENT -- Electrical heater for protection of the components of the electric panel. This is compulsory if the outdoor temperature is lower than -8ºC WB. With an outdoor temperature ower than -16ºC WB will be compulsory a reinforced resistance. -- Compressor with protection for low temperature (supplementary crankcase heater). This is compulsory if the outdoor temperature is lower than -8ºC WB. -- Dampers with spring for automatic closing in case of a tension cut. This is compulsory if the outdoor temperature is lower than -8ºC WB. -- Electrical heater for antifreeze protection of dampers of mixing boxs. This is compulsory if the outdoor temperature is lower than -12ºC WB. -- Circuit of the hot water coil with antifreeze protection according to the water temperature. This is compulsory if the outdoor temperature is lower than -20ºC WB. ■■ Humidity -- Stop-drop in the indoor air coil (optional from model 415 to 960 and included in models 1100 and1200). -- Recommended in cases where a high moisture content in the air is foreseen or when the air flow is high. -- Stop-drop in the outdoor air intake. -- Tropicalised electric panel. -- Tropicalised motors and fans (please consult). Indoor stop-drop ■■ Comfort / heating options -- Hot water auxiliary coil, with three-way valve. This optional always incorporates an anti-freeze thermostat as safety system. -- Auxiliary electrical heaters. With this option, the air flow controller is compulsory to be selected.
