Safety regulations:

Please read the following information carefully before installing and operating the controller. When conﬁguring the controller please utilize some semblance of the recommeded settings illustrated in section 3.2. This will avoid damage to the solar system by common problems such as overheating. Installing the controller using the

default settings without making any adjustments to the conﬁguration parameters is likely to result in an overheating condition of the solar system at some point. Please ensure that the mounting is in accordance to

local, state and federal regulations.

Warning! Switch-off power supply before opening the housing.

The unit is designed for indoor installation only. It is not suitable for installation in hazardous locations and should not be sited near to any electromagnetic ﬁeld. The controller must installed in accordance with all electrical regulations. These regulations vary from region to region. Please contact the appropriate agency in your area if unclear on this.

Wall Mounting Instructions

1. Unscrew the cross-recessed screw of the cover and remove it from the housing.

2. Mark the upper fastening point on the wall and mount the enclosed dowel and screw.

3. Hang up the housing at the upper fastening point and mark the lower fastening point on the wall. The distance between the 2 mounting holes is 130 mm.

4. Fasten the housing at its lower point..

Relay output

Line voltage input

The power supply to the controller must only be made by an external power supply switch and the line voltage must be 120 VAC (50/60 Hz). Flexible lines are to be ﬁxed at the housing by enclosed strain relief supports and screws.

The SOM 6 controller is equipped with 1 relay which is usually connected to the solar loop’s circulator pump.

• Relay 1

18 = Conductor R1 17 = Neutral conductor N 13 = Earth ground

The temperature sensors (S1 to S4) are to be connected to the following terminals (not polarity sensitive):

1 / 2 = Sensor 1 (Collector sensor) 3 / 4 = Sensor 2 (Storage sensor)

5 / 6 = Sensor 3 (For monitoring only) 7 / 8 = Sensor 4 (For monitoring or Energy Production

Measurement)

The power supply is to be connected to the following

terminals:

19 = neutral conductor N

20 = line conductor L 12 = ground terminal

Electrostatic discharge can lead to damage to electronic components!

Hazardous voltage present!

The controller is operated by the 3 keys below the display.

To enter the conﬁguration mode toggle through the display parameters by pressing and releasing key 1 until this no longer causes the display to change. At this point press and hold key 1 until the conﬁguration parameters are displayed (about 5 seconds), then quickly release the key to avoid toggling to the end of the parameter list. The ﬁrst parameter in the list is DT O. To change the setting of a given parameter, follow the steps below.

1. Toggle to the parameter using keys 1 and/or 2. The abbreviation for the parameter is displayed on the right side of the screen, with the setting directly below, and the set icon solid (not blinking) on the extreme right.

2. Press key 3. The set icon begins blinking signifying that the parameter may now be adjusted.

3. Quickly use keys 1 and/or 2 to change the setting to that which is required.

4. Press key 3 again. The set icon stops blinking signifying that the new value has been stored.

The system display consists of an indication channel, a tool bar, and the system screen. These are detailed below.

The indication channel consists of two lines. The upper line is an alphanumeric 16-segment display, in which an abbreviation of the current setting or reading is shown. In the lower 7-segment display, the value of said reading or setting is shown.

The additional symbols of the tool bar indicate the current system status.
