Could you help me and share with me your experience about cooling mode at low ambient temperature ( up to -15 °C - Cold region ) for Utopia ES & Utopia IVX ( IVX Premium / IVX Comfort ) .
Could you send us some instructions ( case studies; technical papers; brochures & leaflets ) how to get cooling performance in ambient air temperatures up to -15 °C.
HITACHI in official technical catalogue put only that working range for Utopia ES & Utopia IVX = -5 °C and we have pressure from market for units which can cooling up to -15 °C.
From my many years experience HITACHI has no problem with temperature limit in cooling mode but it will be very good to have some papers as support.
Thank you.
