PROGRAMMING INSTRUCTIONS

The SMMC-3 program has been structured into 6 levels; within each of these levels are further degrees of selection. Each programming step is clearly described on the LCD, and easily adjusted by the “UP”, “DOWN”, and “SET” buttons.

During programming:

∙All regular operating functions of the SMMC-3 are suspended.

∙If a button is not pressed for approximately 90 seconds, the program will return to normal operation, saving programming changes made up to the point exited.

∙Pressing the BACK button results in an exit from the programming sequence, with the changes made up to that point saved.

Resetting to Factory Conditions

When the SMMC-3 is first energized, and during the time the initial LCD display (SMMC Ver. X.X) screen shows push the UP and DOWN buttons simultaneously to access the option to revert to factory set conditions. Use the UP or DOWN button to select “yes” or “no”; the program accepts the selection and returns to normal operation.

To begin programming the SMMC-3 hold the SET button down for 5 seconds. The display will start in program level 1. To move to other levels use the UP or DOWN buttons.

Level 1. Temperature Unit Selection

PROGRAM MODE 1. Degree: °C or °F

The default temperature units setting is °F.

To move to the next level use the UP or DOWN buttons. Press the SET button to select the temperature display units.

1. Degree: °C or °F

<°C >

<°F >

Pressing UP selects Degrees C. Pressing DOWN selects Degrees F.

After pressing the UP or DOWN button, the program automatically accepts the selection and advances to the next program level.

Level 2. Operating Mode Selection

PROGRAM MODE 2.Mode: 1 or 2

The default mode setting is Mode 1.

To move to the next level use the UP or DOWN buttons. Press the SET button to select the operating mode.

2.Mode: 1	or 2
<No.1 >	<No.2 >

Pressing UP selects Mode 1 (Independent). Pressing DOWN selects Mode 2 (Priority).

After pressing the UP button for Mode 1, the program automatically accepts the selection and advances to the next program level.

After pressing the DOWN button for Mode 2, the program automatically accepts the selection and then moves to another input screen, as shown below.

2.Mode No.2 <2zones> <3zones>

Pressing UP selects a 2 Zone system (Zone 1 & 2). Pressing DOWN selects a 3 Zone system (Zone 1, 2 & 3). After pressing the UP or DOWN button, the program automatically accepts the selection and advances to the next program level.

Level 3. Sensor Activation/De-activation

PROGRAM MODE 3.Sensor Activation

The default sensor activation setting is for an aerial (SMAS- 1), or gutter (SMGS-1) sensor, zone 1.

To move to the next level use the UP or DOWN buttons. Press the SET button to begin the process to activate or deactivate sensors. Each of the 3 control zones may have up to 2 individual sensors, for a total of 6 sensors. <A/G.ZoneX> refers to either an SMAS-1 or SMGS-1 sensor, <P.ZoneX>, refers to an SMPS-1 in-ground sensor. The activation/deactivation operation for all 6 sensors must be stepped through before this operation is complete.

3.Sensor Activation Yes <A/G.Zone1> No

3.Sensor Activation Yes <A/G.Zone2> No

3.Sensor Activation Yes <A/G.Zone3> No

3.Sensor Activation Yes <P.Zone1> No

3.Sensor Activation Yes <P.Zone2> No

3.Sensor Activation Yes <P.Zone3> No
