v. Power Limiting Factor – Sets the % of heater output allowed by the
controller
1. L###, where ### is a percentage from 001 to 100
(Factory Default 100). This feature allows a user
to limit the kW rating of the unit by a specific percentage and
effectively lower the total amp draw of the unit. (NOTE; The
electrical service still needs to be sized for the total amperage
listed on equipment nameplate.)
vi. Heater Configuration – Sets the controller to perform calculations based
on the heater configuration of the unit.
1. E001, for single-phase one heating element and all 3-
phase units
2. E002, for single-phase two heating elements
3. E003, for single-phase three or six heating elements
4. E004, for single-phase four heating elements
vii. Calibration – Used to calibrate the heater. (For factory use only)
1. CA #, where ## equals the degrees of calibration
from -3 to 3. Default is 0.
viii. Low/High Flow – Sets the unit as either a low flow or high flow unit.
1. LF, for low flow (Factory Default).
2. HF, for high flow.
ix. Remote Control – Sets the operation of the remote control
function (see Priority and Remote Controls in this section).
1. iPOF, disables the remote control (Factory
Default).
2. iPHi, 24VDC signal connected to P1 and P2 or closed relay
connected to P2 and P3 will allow the heater to operate and loss of
24VDC signal or open relay connected to P2 and P3 will inhibit the
heater operation.
3. iPLo, 24VDC signal connected to P1 and P2 or closed relay
connected to P2 and P3 will inhibit the heater operation and loss of
24VDC signal or open relay connected to P2 and P3 will allow the
heater to operate.
4. When the remote control operation is inhibiting
the unit from operating the display will show hLd.
x. Display Lock – Allows the user to lock the heater parameters. When the
display is locked the temperature setpoint cannot be
changed and although the configuration menu will still be
accessible, no changes can be made to any parameters,
