INSTALLATION
OJ GreenZone™ Module A should be fitted to a standard 35 mm DIN rail mounted in an
enclosure corresponding to the installation site classification (see fig. 2 for unit dimen-
sions). The unit itself is classed as IP20 and ETT-KH from OJ Electronics can be used
for such covering purposes. The most practical location will often be in the vicinity of
other components, valves, sensors, etc. associated with the VAV zone. An overview of
the physical configuration of the system is given in fig. 19.
An ideal location would be above a suspended ceiling panel. OJ GreenZone™ Module
A must be provided with a 24 VAC, +/-15% power supply and is therefore equipped
with looping terminals (max. 1.5 mm2) for the purpose (see figs 8 and 9). Other connec-
tions are made by means of a combination of RJ12 connectors and screw terminals for
connecting wires of max. 1.5 mm2 cross-sectional area (see fig. 3).
Connections and indications
(see overview in fig. 1)
In fig. 3, all connectors are marked with a letter (A – P).
See below for descriptions of electrical connection of the various components, inputs
and outputs, and other signals and indications of the OJ GreenZone™ Module A.
Connection of VAV damper motors
(see figs 3, 14 & 14A)
OJ GreenZone™ Module A can control two VAV dampers: one VAV damper in the
exhaust duct and one VAV damper in the inlet duct. The VAV damper motors are con-
trolled by means of a 0-10 V signal.
• The VAV damper motor in the zone's exhaust duct should be connected to terminals
18, 19 & 20 (see fig. 14)
• The VAV damper motor in the zone's inlet duct should be connected to terminals 21,
22 & 23 (see fig. 14A)
Connection of valve motors for heating and cooling systems
(see figs 3, 16 & 16A)
OJ GreenZone™ Module A can control two 0-10 V valve motors: one valve motor for
any heating element located in the inlet duct and one valve motor for any cooling ele-
ment located in the inlet duct. The valve motors are controlled by a 0-10 V signal.
