Thermostat Staging – On all immersion thermostat models, 24 kW and above (18 kW for 208V), additional thermostats can be
provided so that the maximum element input will not exceed 18 kW - 27 kW per step. Temperature differential between steps can
be set as desired.
Note: Thermostat staging recommended on 81 and 108 kW models.
