Applications
The 193 HC Hesitation Free Energy
Band Heating/Cooling Pneumatic
Room Thermostat is an excellent
choice for saving energy by sequencing heating and cooling valves. In
most heat/cool pneumatic applications, a 3 to 8 psi (21 to 55 kPa)
heating valve and a 10 to 14 psi (69 to 103 kPa) cooling valve are used.
By design, this provides a 2 psi (14 kPa) deadband where no heating
and cooling is occurring. The hesitation feature allows you to change
the deadband range to a 3, 4 or 5 psi (21, 28, or 34 kPa) range to save
energy.
