CONTROL THERMOSTAT
The water heater is supplied with a single stage immersion thermostatic
switch that is installed and wired at the factory. The thermostat can be
adjusted through a range of 100° - 195° F, (an optional low range, 30° -
110° F, is available), and is adjustable with a flat tip screwdriver. Other
thermostatic controls are available, see Options below.
TEMPERATURE HIGH LIMIT SWITCH
As a safety device, either a surface mounted high temperature cut-off switch with manual reset, factory
set at 205° F, or an optional immersion high temperature cut-off switch with manual reset, adjustable
through a range of 100° - 240° F, is provided. In the event of an over-temperature condition, the
thermostat will disengage the power from the system. The high limit must be manually reset thereafter
to restart the heater.

MAGNETIC CONTACTOR
The magnetic contactor(s) is a heavy-duty resistive load type
rated for 100,000 cycles. The contactor supplies power to the
heating element(s) based on the resistive load (non-inductive) of
the heater only when the thermostatic switch is engaged, thereby
pulling in the contacts until the desired temperature is reached.
At this point, the contacts will drop out, which in turn
disconnects power from the elements.
