CONTROL THERMOSTAT
The control panel is supplied standard with a single-stage immersion thermostatic switch. As an
optional any of the following may be supplied; a four-stage immersion thermostatic switch, a solid-state
staging controller with thermistor, or a digital 1/16 DIN temperature controller with thermocouple. See
drawing for specific details. The single-stage immersion thermostat can be adjusted through a range of
100° - 190° F. A low range, (30° - 110° F), operating thermostat is also available in the single-stage
version. The four-stage immersion thermostat can be adjusted through a range of 100° - 250° F and is
capable of switching four circuits. The solid-state staging controller automatically brings on-line the
required number of heating steps in order to meet the hot water demand and will also operate each
circuit in a circular mode to allow for equal usage of all heating circuits. The thermostat is adjustable to
the desired temperature by turning the dial on the pot switch. A 1/16 DIN electronic temperature
control package may be installed. A separate manufacturer’s operating manual will be supplied with all
units except the single-stage immersion thermostat.
