GENERAL

• The MULTI-REG Control for ECOWATT EC Fans to provide Demand Ventilation Speed Control for dedicated control of the S&P ECOWATT EC ranges and full BMS compatibility.
• For up to two ECOWATT (EC) Fans – the MULTI-REG’s 0-10V output signals are routed directly to the fan.

3.1. Speed Control Inputs

• Variable Speed Control
• Manual variable speed control via an optional secondary S&P REB ECOWATT or REB-CVF controller, or
• Automated variable speed control via a 0-10V signal from an external source.

3.2. Installer-defined Fixed Speed Control

• An upon-installation defined duty either continuous or on-demand (triggered by an external switch), or
• One, two or three speeds defined during installation to provide a minimum/middle/maximum speed ventilation system, the middle and maximum speeds being selected by an external switch/sensor (either Volt-free and/or 230V).
• Note that there is a 3-Volt minimum output to the fan to ensure start-up momentum.

3.3. Remote Switching

• The switching between the (up to) three speeds can be activated by either:
• (Up to) Three Volt-free contacts, or
• (Up to) Three 230V supply inputs
• On/Off – Volt-Free Contact and/or 230V
• External Fire Fan Shut-Off Switch – An external “Fire” switch (Volt-Free) can be connected, If the switch opens signifying that the fire alarm has been activated, then the MULTI-REG Controller will automatically stop the fan.

3.4. Fan-Fail Detection by Fault Sensing

• Automatic monitoring of the impeller rotation via the Tacho pulse (frequency generator) signal.
• Low current sensing to indicate a connection open circuit problem.
• Sixty seconds time-delay of fault detection on start-up to allow input levels to normalise.
• Facility to connect an Airflow Switch or Differential Pressure Switch (DPS), for use on fans where other options are not practical. There is approximately a 60 seconds delay in the operation of the airflow switch monitoring system, to allow full airflow to  develop.

3.5. Outputs

• Digital Display
• Running, Stopped and/or fault condition.
• Fan speed percentage and 0-10V output condition.
• Countdown to fault status monitoring condition (allows fan to gain speed).
• Diagnostic – Reasons for fan stop/fail.

3.6. Analog Switch Outputs

• Output to BMS of fan run and fault indicated by an individual set of contacts capable of controlling a maximum load of up to 230 Volts at 8 Amps.
• Provision to operate a system damper actuator (can be supplied as an accessory). When the fan is running, the damper opens, when the fan is stopped (either intentionally or in a fault condition) the actuator spring return facility closes the damper.

SAFETY RULES

4.1. WARNING

• Mains voltage is present. It is the responsibility of the user to ensure compliance with the Health and Safety at Work Act, 1974.
• Isolate mains supply before connecting.
