Fig. 29
This example shows a two temperature application utilizing a mixing valve. The supply water coming out of the unit will be
set to only one temperature. When the supply temperature reaches the low temperature zone the water will be tempered
down using a mixing valve to mix the supply temperature from the primary loop with the return temperature from the low
temperature zone providing low temperature water to that zone.
