• For software revision A13 and older: When this parameter is programmed for electric heat, only the electric-heat

relay located toward the middle of the circuit board is energized during a heating cycle (see “Sample Wiring Diagram”

on page 21).

• For software revision A15 and newer: When programmed for electric heat, both the electric-heater relay and the

valve relay are energized. This change supports newer circuit board revisions without the electric-heater relay.

Therefore, circuit boards that do not have electric-heater relays require a display with software revision A15 or newer

to properly energize the valve relay. Also, since the valve-relay output only supports a maximum of 15 amps at 115VAC

or 10 amps at 230 VAC (circuit boards revision F and newer) of resistive load, when installing an optional electric

heater that exceeds this load, it is necessary to install an additional contactor that is rated to handle the full load of the

electric heater. Please consult with Dometic Customer Service or with an authorized service technician for assistance.

P-14: Fan Motor Selection

The “SC” (Split Capacitor) default setting is correct for air conditioning unitswith high-velocity blowers. Only change the setting

to “SP” if your unit has a Shaded Pole fan motor, recognizable by a blower-motor overhang. (The SC motor of a high-velocity

unit is inside the blower, and the unit has “VTD” or “HV” in the model number.)

P-15: Reset Memorized Defaults

To reset all programming parameters set this parameter to “rSt”. This restores all programmable parameters to the last saved

default values. Once new values are entered and memorized the factory defaults are overwritten, and the new parameters

become the default values. To restore the original factory default parameters manually, refer to Table 2, page 12.

P-17: (Reserved for future use.)

P-18: Air Filter Cleaning/Replacement Timer Setting

(Available only in software revision A15 and newer.) Use this feature for a reminder to clean or replace the unit’s air filter.

The parameter entered represents that number times 10 hours. Select the number of operating hours until the filter reminder

appears. Parameter choices are between 10 (100 hours) and 250 (2500 hours). Dometic recommends that you check the air

filter at least every 500 hours of operation. The default setting is off, designated with “00”.

Once set, the timer keeps track of the total amount of run hours that the fan accumulates (see P-19). Once the timer setting is

reached, “FIL” flashes briefly on the LED display every 10 seconds until it is cleared. Display of the room temperature continues

and the normal operation of the system is not affected. The “FIL” reminder can only be cleared and the timer reset via

programmable parameter P-19. See below for instructions.

P-19: Filter Cleaning/Replacement Timer Value & Reset

(Available only in software revision A15 and newer.) This parameter displays the current elapsed time (in hours times 10)

since the timer was started or reset. For example, if the value of P-19 is “30”, then between 300-399 hours have elapsed since

the timer was started or reset. Once the value of P-19 reaches the value set in P-18 (explained above), “FIL” flashes on the LED

display every 10 seconds until it is cleared. To clear the “FIL” reminder, press either the Up or Down button while viewing the P-

19 parameter. This resets P-19 to 0 and restarts the timer.

P-20: CAN-bus Unit ID

(Available only in software revision A16 and newer.) This parameter displays only when CAN-bus network capability is

available and the Elite is plugged into a networked Passport I/O power and logic board. This parameter does not display when

the Elite is plugged into a standard board. Each control on the same CAN-bus network must be assigned a unique Unit ID (0 -

255). For example, the control that has P-20 set to 5 will respond to commands with a destination address of 5.

P-21: CAN-bus Group ID

(Available only in software revision A16 and newer.) This parameter displays only when CAN-bus network capability is

available and the Elite is plugged into a networked Passport I/O power and logic board. This parameter does not display when

the Elite is plugged into a standard board. Assign the address for the control’s CAN-bus network group (0 - 255). This number

should be unique and different than any CAN-bus Unit ID. For example, all controls that have P-21 set to 100 will respond to

commands with a destination address of 100 (in addition to responding to commands that target their individual Unit IDs).

P-22: Voltage Calibration

(Available only in software revision A15 and newer.) This feature displays the voltage being read by the power and logic

circuit board. It displays a live reading of the voltage and can be manipulated by pressing the Up or Down buttons. Calibrating

this parameter provides a more accurate voltage level when calculating low voltage for P-6. Use a reliable voltmeter as a

reference when adjusting this parameter.

P-23: Set Point Temperature Differential

(Available only in software revision B23 and newer.) This parameter is the temperature differential in Fahrenheit for all

modes of operation: Automatic, Cool, or Heat. Refer to “Modes of Operation” on page 5 for more information on how this

parameter affects these modes. By default, this parameter setting is 2°F (1.1°C). It can be set to either 1°F (0.55°C) or 2°F

(1.1°C). Setting this parameter to 1°F (0.55°C) will result in the control maintaining the room temperature closer to the desired

set point. However, this may result in more frequent shorter-duration cooling or heating cycles. In most cases, the factory default
