Swegon TBLZ-3-50 Instruction For The Installation

GB.TBLZ350.170214

Instructions for the Installation of the type TBLZ-3-50
Zone Control Box (X zone)
GOLD

1. General

The zone control box consists of two IQlogic+ modules
and one transformer (230 VAC/24 VAC) mounted inside a
metallic enclosure.
Necessary wiring terminals are provided for connection
to external components. The metallic enclosure has cable
gland screw caps for cable entry.
See also the separate guide to the Xzone functions.

2. Range of Application

Sometimes more than one temperature zone is required in
a ventilation system. Different temperature needs in vari­ous parts of a building may be due to the perimeter wall
of the building facing north or south, diverse operations
conducted inside or other reasons, for instance. The func­tion is designed for one extra temperature zone, max.

3. Installation

Secure the zone control box to a wall, the air handling unit
or the like by means of four screws.

5. Function

GB.TBLZ350.170214

5.1 Xzone heating
(wiring terminals 101-114)

IQlogic+module 1 is used for the extra heating control
zone function (function selector switch 1 is set to Position
A).

The function can be enabled in the hand-held micro termi­nal of the GOLD unit or via a communication interface.

The module controls an electric air heater or an air heater
for hot water.

Connect the 0-10 VDC control signal of electric air heater
or valve actuator to the IQlogic
connector.

Connect the conductors from the pump, if fitted, to Termi­nals 101 and 102.

Connect the pump alarm, if required, to Terminals 103
and 104.

Connect the freeze guard sensor of the air heater for
water to the IQlogic

+

-module with an RJ 45 connector.

Connect the conductors from the supply air temperature
sensor (TBLZ-1-30) to wiring terminals 113 and 114.

See 6. Electrical connections on the next page.

5.2 Xzone cooling
(wiring terminals 115-132)

IQlogic+module 2 is used for the extra cooling control zone
function (function selector switch 2 is set to Position B).
Always use this module for extract air control/room air
control even if the room is not being cooled. However,
there’s no need to enable the cooling function in the
hand-held micro terminal of the GOLD unit.

The function can be enabled in the hand-held micro termi­nal of the GOLD unit or via a communication interface.

The module controls a DX air cooler or an air cooler for
chilled water.

Connect the 0-10 VDC control signal of valve actuator to
the IQlogic

Connect the Cooling step 1/Pump 1 connectors (relay
output) to Terminals 115 and 116.

Connect the Cooling step 2/Pump 2 connectors (relay
output) to Terminals 117 and 118.

Connect the Cooling step 1/Pump 1 Alarm conductors to
Terminals 119 and 120.

Connect the Cooling step 2/Pump 2 Alarm conductors to
Terminals 121 and 122.

Connect the temperature sensor in the extract air duct
(TBLZ-1-30), if required, to Terminals 131 and 132.

Connect room sensor, TBLZ-24-2 (1-4 sensors), if required,
to the IQlogic
installation instructions.
