Chilled Beam 2-Pipe Heating and Cooling with Changeover

An STE-1454/1455 strap-on (Type III) temperature
sensor provides the CTE-5202 an automatic change-
over for heating/cooling applications using hot and
chilled water. The sensor will switch the thermostat
between cooling and heating modes based on
the temperature of the water in the pipe. A water
temperature higher than changeover temperature,
switches control to heating mode, and a temperature
lower than changeover temperature, switches con-
trol to cooling mode.
