Pressure Switch
With the unit running, program a set point of 30ºF (-1ºC). Allow the process
temperature to drop under 100ºF (38ºC). When the process temperature reaches that
point, turn off the water supply. The pump should stop and the Low Water Pressure
indicator should illuminate. Turn the water supply on to reset the pressure switch.
Adjusting the Pressure Switch
The pressure switch used in your Water Temperature Control Unit is factory set at 16
psig (110.3 kPa/1.1 bars). However, if the process does not require the unit to operate at
250ºF (121ºC), you can adjust the switch to meet your process needs.
