Thermostat Staging –
On all immersion thermostat
models, 24 kW and above
(18kW 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 81kW models.
