2. dSP2, to display measured inlet temperature intermittently with
setpoint temperature.
a. Inlet temperature is displayed as i###
3. dSP3, to display measured outlet temperature intermittently with
setpoint temperature.
a. Outlet temperature is displayed as o###
4. dSP4, to display measured flow rate intermittently with setpoint
temperature
a. Flow rate is displayed as F##.#, in tenths of a gallon or liter.
5. dSP5, to display inlet temp, outlet temp, flow rate and setpoint all
intermittently.
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.
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 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 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.
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, except to change the display lock. With the
display lock on, attempting to change the temperature setpoint will cause
the display to show, Locd.
1. LcOn, to turn the display lock on.
2. LcOF, to turn the display lock off (Factory
Default).
xi. Software Version – Displays the version number of the software
1. Sd##, where ## is the version of the display software.
2. Sb##, where ## is the version of the main board software.
h. After this menu item, the configuration menu cycles back to the first item.
