General Data
Electric Heat
All Force-Flo cabinet heaters, except inverted models M and N, are available with electric heating
coils as a standard option.
Coil Construction
Electric heat coils are open wire type with a nickel chromium element design.
Power Supply
Units have single-point power since the electric heating elements operate on line voltage. Electric
heat is available as 208/60/1, 230/60/1, 277/60/1, 208/60/3, or 480/60/3. Electric heat coils operate on
the same voltage as the unit, except for units with 480/60/3 electric heat. In this case, the unit
operates at 277/60/1, thus requiring a 4-wire supply. All fans and motors are single phase. In
addition, all control options are 24-volt, utilizing a factory-installed transformer.
Power Supply Location
All electric heat cabinet heaters have a terminal block for main power on the unit’s right-hand side.
Control Type
Single-stage electric heat units are controlled by either Tracer UC400, ZN010, ZN510, or ZN520
control options. Two-stage electric heat is controlled by the Tracer UC400, ZN520 only. Both
control options use PWM (pulse-width modulation) outputs to calculate the electric heat output
