Swegon MIRU Function Manual

MIRU Control Function Guide,
GOLD/MIRUVENT
1. General
The MIRU fan control system can control one type MIRU-
VENT power roof ventilator.
Up to ten power roof ventilators with MIRU Control
equipment can be connected to one GOLD air handling
unit by means of bus communication (requires GOLD
program version 6.03 or better).
This guide is meant for use as guidance in the electrical
wiring and commissioning of MIRU Control equipment in
combination with a MIRUVENT power roof ventilator. The
function guide also deals with the electrical connections
betweenMIRU Control and GOLD air handling units.
The fan motor in the MIRUVENT power roof ventilator
should be a type AC motor with integrated frequency
inverter, or EC motor with integrated motor control system
that communicates with MIRU Control via Modbus.
Swegon reserves the right to alter specifications.
2. Material Specification
Control of MIRUVENT fan via MIRU Control:
MIRU Control equipment
MIRUVENT fan with type code
x = model and size codes
Pressure sensor, pressure regulation
Pressure sensor, flow measurement
aa = code for cable length in metres.
The cable from the pressure sensors must be long enough
to reach the MIRU Control equipment.
Outdoor temperature sensor
Wiring to the GOLD unit:
Connection kit:
Contains cable adapter and communication cable.
Miscellaneous:
3-wire cable for communication to the MIRUVENT fan:
2-wire cable for possible outdoor temperature sensor.
Cable for supply voltage to MIRU Control, 230 V.
Cable for supply voltage to the MIRUVENT fan.
1 x 230 V or 3 x 400 V, see separate installation instruc-
tions for the MIRUVENT.
* At least one pressure sensor for either pressure regulation or flow
measurement is mandatory. Two pressure sensors are possible, one for
pressure regulation and one for reading the flow.
** For outdoor temperature compensation only
