2.2 How to configure your RWF40

Shown at the right is the basic display.

The current configuration of your specific controller will determine which levels you will be allowed to access.

C112 must be xxx0 to access the configuration level.

The C112 locking code can only be adjusted by the manufacturer.

To reach the configuration level, you start from

the basic display, (shown above), skip past the user level, and go first, to the parameter level, and then, finally, to the configuration level.

Press and hold for 3 seconds, and then release it.

You are now at the parameter level.

From the parameter level you may now advance to the configuration level,

by pressing again, holding, for 3 seconds, and then releasing it.

The actual value display, (9030) shows the current configuration value.

The setpoint display, (C111)

shows the configuration item you are adjusting.

Configuration level items summary :

C111	Analog input 1	sensors (14 types), standard signal
	Analog input 2	none, external SP, analog SP Shift
	Analog input 3	none, outdoor sensors …
	D2 function	none, SP chg/over, SP binary shift
C112	Limit comparator	none, input 1,2,3 …
	Controller type	3-position, modulating 0-20mA, …
	Setpoint SP1	via buttons, with outside sensor
	Locking	none, configuration, parameters, buttons
C113	Unit address	0-9
	Unit address	0-9
	Decimal - Units	º C or º F and decimals
	Signal out-of-range	limit comparator OFF/ON
SCL	SCale Low Analog input 1
SCH	SCale High Analog input 1
SCL2	SCale Low Analog input 2
SCH	SCale High Analog input 2
SPL	Set Point, Lower
SPH	Set Point, Higher
OFF1	Actual value correction, OFFset, Analog input 1
OFF2	Actual value correction, OFFset, Analog input 2
OFF2	Actual value correction, OFFset, Analog input 3
Df1	Digital filter time constant for Analog input 1

Example Re-configure (adjust) the value for C111

If no keys are pressed for 30 seconds, at anytime, the controller will automatically return to the basic display.

The current value of C111, (9030) is shown in the actual value display.

The current configuration item (C111) is shown in the setpoint display.

The display is steady, (not flashing) and by default, the 4th, (rightmost) digit is the one you may now adjust.

You can select the digit you want to adjust,

by pressing once and releasing it.

The 3rd digit is now flashing,

indicating that it is now, the adjustable digit.

(Each time you press and release you cycle, thru each digit, right-to-left and back again)

To change the value of the flashing digit,

press and release it.

Each time you press and release, you cycle up thru the allowable values, and back again.

Once you have the desired value displayed and flashing,

you may accept it by pressing once and releasing it.

All four upper digits will flash once.

The controller displays the new configuration values, in 4 steady digits.

Your options at this point are:

Press and release, to immediately return to the basic display. or

press and release it, to advance to C112,

press again and release it, to advance to C113,

press and release it, to advance to SCL, … after the last configuration item Df1,

press and release it, to advance to AL, (the 1st parameter), … after the last parameter item P,

press and release it, to advance to SP1, (the 1st user item), … after the last user item it cycles back to the 1st user item.

Or simply wait 30 seconds and the controller will automatically return to the basic display.
