Frequently Asked Questions - Control ECOWATT Soler & Palau

What are the operating modes of the Control ECOWATT?

The regulator offers three modes: Proportional Integral (PI) for constant pressure, Proportional with one to three analog inputs, and Mini-Maxi with digital inputs (contact).

How to change the operating mode?

After powering on, press one of the four buttons on the front (within 10s). Use the – or + keys to select the desired mode (factory setting: Proportional Integral).

Which sensors can be connected to the analog inputs?

Inputs S1, S2, and S3 accept pressure, relative humidity, CO2, or temperature sensors, with 0-10V or 4-20mA signals. Set the micro-switches to 'V' or 'mA' according to the sensor type.

How to perform a factory reset?

Press and hold the – and + keys simultaneously for 5 seconds until 'RESET' appears. Press + to confirm, then press ▲ to validate the reset.

What to do if the ERROR LED lights up?

The ERROR LED and alarm relay activate if a sensor reads 0 for 2s (displays 'S1 ERROR') or if alarm thresholds are exceeded (displays 'S1 ALARM'). Check sensor connections and alarm settings.

How to set the minimum and maximum motor speed?

Press ▲ and ▼ simultaneously to access 'MIN-OUTPUT' (0-50%, factory 10%) and 'MAX-OUTPUT' (50-100%, factory 100%) settings. Use – and + to adjust.

Can I control a slave fan?

Yes, on the AC/DC version, the slave output (terminals 12-13 of J10) allows controlling a second fan with a 0-10V signal. The parameter 'Slave-OUT' (50-150%, factory 100%) sets the maximum slave speed.

What is the minimum output voltage for the AC/4A version?

The minimum voltage is adjustable from 80V to 150V via micro-switches. The switch positions (ON=0) determine the value: 000=80V, 001=90V, ... 111=150V.

How to install the regulator?

Mount the enclosure on a vertical wall, in a technical room, with cable glands facing downwards. Leave space around for heat dissipation. Use cables with a cross-section of 1 to 2.5 mm².

What safety precautions must be observed?

Installation and adjustments must be carried out by a professional electrician. Disconnect the power supply before any intervention. Do not touch live parts. Check that the supply voltage matches the specifications.

The range includes three models differentiated by input and motor output:

• CONTROL ECOWATT AC/DC: model with AC input and 0-10V analogical output for DC motors or frequency converters (Fig.1).
• CONTROL ECOWATT AC/4A: model with single-phase AC input and voltage output for single-phase motors up to 4A. With this model, 0-10V analogical outputs for DC motors or frequency converters are also active (Fig.2).

Each model has three function modes:

• Proportional Integral control (PI) with analogical input (0-10V / 4-20mA)
• Control with three analogical inputs (0-10V / 4-20mA)
• Control with three digital inputs

CONTROL ECOWATT AC/DC incorporates an analogical output and can control both master and slave fans.

"PROPORTIONAL" mode

In this mode, the CONTROL ECOWATT is set up to work with one, two or three analogical inputs (J6, J7 or J8), 4-20mA or 0-10V. The CONTROL ECOWATT functions in accordance with the parameter of maximum demand. The sensors are connected in the inputs S1(J6), S2(J7) and S3(J8). Depending on the type of sensor (4-20mA or 0-10V) set the micro switch fitted in the circuit board to "mA" or "V".

To change input settings from factory settings:

• Press any of the 4 keys on the front panel.
• "IN1 Type" appears on the display. This parameter allows the selection of the measure unit for the channel 1 (sensor 1). The admitted measure units are:
• “OFF” to inactivate the channel when any sensor is connected.
  o “%(V)” relative humidity sensor (RH%) connected to channel 1 with 0-10Vdc output.
  o “%(mA)” relative humidity sensor (RH%) connected to channel 1 with 4-20mA output.
  o "CO2(V)" CO2 sensor (PPM) connected to channel 1 with 0-10Vdc output.
  o “CO2(mA)” CO2 sensor (PPM) connected to channel 1 with 4-20mA output

LED ERROR - OUTPUT RELAYS

CONTROL ECOWATT models include an LED "ERROR" on the front panel and in the circuit of the two relays RL1 and RL2. They have the following functions:

The function of relay 1 (J13) is Alarm or Error, together with the LED "ERROR".

Activation:

1. When all the sensors read 0 for 2s. The J13 relay is locked and the LED "ERROR" is lit. "S1 ERROR" appears on the display.
   If this happens, check the sensor connections that show "error" on the display.

2. In the PROPORTIONAL setting, when the alarm sensor limits are exceeded (S1 ALARM, S2 ALARM, S3 ALARM). The LED "ERROR" flashes twice. "S1 ALARM" appears on the display.

The function of relay 2 (J5), in the MIN-MAX setting, is to activate the high speed of a two-speed motor (2-windings single phase motor) when there is a change of input
