■ Velleman modules are not suitable for use or as part of life support systems, or systems that might create hazardous situations of kind.

Introduction:

Thank you for choosing Velleman. This multifunctional digital thermostat module allows you to control and monitor the room temperature.

Modules needed:

Apart from the VM148 module, you will be needing a 12VDC power supply. Use an external contactor with currents higher than 3A.

Possibilities:

- The module allows you to maintain the room temperature between 2 programmed limits. Example: The room temperature must not drop below 20^ . Once the heating is activated, the room temperature must reach 22^ before being deactivated.

• Control of the air conditioning system.

• Temperature monitoring in e.g. a housing or greenhouse, of a liquid...).

General definitions:

Hysteresis: Temperature difference between temp° A and temp °B (min. 0.5°C). Temp°A will automatically rise with 0.5°C if the two temperature settings have been programmed identically.

Heating mode: Activation of the heating when the measured temperature ≤ programmed temperature B until the measured temperature > programmed temperature A. Heating mode is activated when temp°A > temp°B.

Cooling mode: Activation of the air conditioning system when the measured temperature > programmed temperature B until the ambient temperature drops below programmed temperature A. Cooling mode is activated when temp°A < temp°B.

A red dot is displayed in the right corner below when the relay, and consequently the connected device, is activated.

Temperature display: The actual temperature and the settings can be displayed in ° Celsius and ° Fahrenheit.

2. SET-UP

The actual measured temperature is displayed at power-on or in normal mode.

Press to access the set-up menu.

3. ERROR INDICATIONS

UnFL – Underflow error: The measured temperature is lower than the minimum measurable temperature (min. temp° = -18°C of 0°F).

OvFL – Overflow error: The measured temperature is higher than the maximum measurable temperature (max. temp° = +60°C of 146°F).

SEnS – Sensor error: Sensor problem or faulty connection.

Press ENTER to display the operation mode of the temperature controller.

Heating mode: temp° A > temp° B

Cooling mode: temp° A < temp° B

5. TEMPERATURE MODIFICATION

This handy function allows you to modify the temperature directly without reprogramming the max. and min. values (temp° A and temp° B). the limit values will automatically shift with the temperature modification.

Shortly press UP ▲ or DOWN ▼ in the temperature display to display the average target temperature.

Temp. A Temp. B Example: temp° A = 22°C, temp° B = 20°C à target temperature = 21°C. Relay on

Repeatedly press UP ▲ or DOWN ▼ to rise or lower the target temperature. Example: Set the target temperature to 25°C; temp° A and temp° B will automatically be modified to 26°C and 24°C.

6. FACTORY SETTINGS

Remove the power supply to the module. Hold ENTER pressed and re-establish the power supply to the module. DEF (default) will be displayed. Release the ENTER button. The display will show the firmware version code.
