Disclosed is an automatic switching two pipe hydronic system for conditioning a space. In one embodiment the two pipe hydronic system enables automatic switching from a first mode of operation to a second mode of operation or vice versa in a reduced span of time. The present invention saves fuel, energy and water, when there are lower load conditions that affect boilers, chillers, and cooling towers. In another embodiment, the present invention provides a system for simultaneously heating and cooling a first portion and a second portion of a space by utilizing a plurality of boilers, chillers, heat exchangers, condenser pumps and closed loop pumps by using a plurality of sensors indicating the temperatures inside and outside the space and a controlling module controlling the operation of the system. The present invention can be easily achieved by making minor configurational modifications to existing systems thereby increases system versatility.
