Pressing UP activates the selected sensor. Pressing DOWN de-activates the selected sensor.

After pressing the UP or DOWN button for <P.Zone3>, the program automatically accepts the selections and advances to the next program level.

Level 4. Ambient Off Temperature Setting

PROGRAM MODE 4.Ambient Off Temp.

The default ambient off temperature is 37°F (3°C).

To move to the next level use the UP or DOWN buttons.

Press the SET button to adjust the ambient off temperature, the temperature above which the SMMC-3 will no longer energize the heating equipment. The minimum and maximum settings possible are noted on the LCD.

4.Ambient Off Temp. min.34 <37°F> Max.50

Pressing UP increases the degree setting. Pressing DOWN decreases the degree setting.

Press the SET button to accept the chosen ambient off temperature and advances to the next program level.

Level 5. Slab Off Temperature Setting

PROGRAM MODE 5.Slab Off Temp.

The default slab off temperature is 50°F (10°C).

To move to the next level use the UP or DOWN buttons. Press the SET button to adjust the slab off temperature, the temperature above which the SMMC-3 will de-energize the in- ground heating equipment. The minimum and maximum settings possible are noted on the LCD.

5.Slab Off Temp. min.41 <50°F> Max.68

Pressing UP increases the degree setting. Pressing DOWN decreases the degree setting.

Press the SET button to accept the chosen slab off temperature and advances to the next program level.

Level 6. Setting the Relay Hold Time

PROGRAM MODE 6.Relay Hold Time

Press the SET button to adjust the relay hold time for the snow melting zones. The relay hold time is the amount of time the snow melting zone remains energized after the moisture sensor is dry. Each of the 3 zones is set independently, in 0.5 hour increments. The minimum and maximum settings possible are noted on the LCD. The relay hold times for all 3 sensors must be stepped through before this operation is complete.

6.Relay Hold Time Z1 min.0 <3.0H> Max.10

6.Relay Hold Time Z2 min.0 <3.0H> Max.10

6.Relay Hold Time Z3 min.0 <3.0H> Max.10

Pressing UP increases the relay hold time. Pressing DOWN decreases the relay hold time.

Press the SET button to accept the chosen relay hold time and advance to the timing for the next zone.

After the hold time for Zone 3 has been set the program automatically returns to programming Level #1 “Temperature Unit Selection”. To exit the programming sequence and return to normal control operation press the BACK button.

Temperature Stand-by

Whenever the ambient air temperature exceeds the ambient off temp, the SMMC-3 goes into a “temperature stand-by” mode, at which time all moisture sensors are de-activated. As soon as the ambient air temperature drops below the ambient off temp, the sensors are reactivated and operation begins as normal.

Outside T = 10°F

Temperature Stand-by

The default relay hold time is 3.0 hours for all zones.

To move to the next level use the UP or DOWN buttons.
