Aims: Our aim is to analyze excitation of CO and H$_2$O in deeply-embedded intermediate-mass YSOs and compare with low-mass and high-mass YSOs. Methods: Herschel/PACS spectral maps are analyzed for 6 YSOs with bolometric luminosities of $L_\\mathrm{bol}\\sim10^2 - 10^3$ $L_\\odot$. The maps cover spatial scales of $\\sim 10^4$ AU in several CO and H$_2$O lines located in the $\\sim55-210$ $\\mu$m range.
