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.
