9.1 Fuses
Access to internal fuses is by removal of the outer case.
Fuses: 2A 20mm x 5mm type F.
9.2 Power Control
In this model the same heating element is used for 110-120V models and 220-240V models.
Electronic power limiting in the 2132 controller is used to reduce the power in the 220-240V
model.
The correct power limit settings (parameter
OP.Hi
) for the furnace are as follows:
220-240V model:
50%
110-120V model:
100%
Note: To reduce the wattage on 240V to the same as on 120V, a power limit of 25% ought to be
applied. This is not necessary, and would result in poorer temperature control.
