Introduction. Thank you for purchasing
one of our Speedfit Aura 230V Thermostat
models. To use all of the Thermostat
features, the optional communications
cables is required.
The unit can be configured to be a
Programmable Room Thermostat (PRT),
Group Control Thermostat, Group
Thermostat or Hot Water Timer.
Communication between neighbouring
JGSTAT2 and JGSTAT1 Dial Thermostats is
possible via the JGWC Wiring Centre
(pictured below) and the optional
communications cables. More information
can be found on pages 9 and 10.
Safety Information. Use in
accordance with the regulations.
The Aura JGSTAT2 is to be used
for room control of heating and
hot water systems inside
buildings.
Product Compliance. This
product is CE compliant and
meets the following EC
Directives:
RoHS2 2011/65/EU, ElectroMagnetic Compatibility directive
2004/108/EC and Low voltage
directive 2006/95/EC.

centre or complete system.
Sources of danger. The
thermostat must be disconnected
from mains supply before removing
the cover.
For the installer. Please enter

SYSTEM OVERVIEW

Programmable Room Thermostat (PRT). When configured for PRT (see page 31) the
Programmable Room Thermostat mainly works by itself and allows the user to have separate
Time and Temperature control of each zone on the wiring centre. Features like Holiday, Party and
Frost mode have to be set on each individual thermostat. The PRT can be configured for global
heat/cool system changeover if your system supports this. This is achieved from a switched input
from the Wiring Centre (see the Wiring Centre Instruction Manual). Communication Connection
(see page 13) is required to use heat/cool changeover function.
Group Control Thermostat. When configured as a Group Control Thermostat (see page 33),
the unit allows central control of up to 7 Group Thermostats (see below). There can be a
maximum of 2 groups per 8 zone wiring centre. Permanent temperature override, Holiday, Party
and Frost modes can be selected centrally from the Group Control Thermostat. Holiday mode
will also be applied to a timer if applicable. Communication connections (see page 13) are
required for grouping the Group Thermostats. Thermostats can be also globally changed from
heating to cooling thermostats if your system supports this by using the switched input
connection on the JGWC (see the Wiring Centre Instruction Manual) along with the
Communications connections mentioned above.
Group Thermostat. When configured as a Group Thermostat (see page 36), the unit will follow
the time schedule and override modes of the Group Control Thermostat. The Group Thermostat
can have its own programmed temperatures, Manual Override and also be removed from the
group temporarily or permanently. Communication connections are required (see page 13).
Timer. When configured as a Timer (see pages 32 and 34), the unit will operate without
temperature control. In this configuration, the unit can be used as a Hot Water Timer. The Timer
will also follow a Group Control Thermostat when Holiday mode has been activated (requires
communication connections).

Power and Switching cable – used to
power thermostats and drive output.
Grouping and Communication cable.
Communication cable can be used when units are used as individual PRT's for
heat/cool changeover. Please refer to page 13 and the Wiring Centre
Instruction Manual.
While the units can function as standalone PRTs or
Timers, installing this optional inexpensive
Communication cable allows the units to communicate
with each other. This allows a thermostat to assume
convenient remote control of a group. This brings
central control of features such as Time Control,
Holiday and Party functions as well as Frost Control.
The individual group members can leave or re-enter
group control at the push of a button.
Cable size 1.5mm 3 core for L,N,SL and 0.5mm twin for the communication.

The systems below, although not exhaustive show the main
options. The maximum number of groups per JGWC Wiring
Centre is two. The group selection communication cable
must correspond to the group terminals on the JGWC Wiring
Centre. Please refer to the JGWC Instruction Manual.
All digital variants can be
configured from JGSTAT2. Groups
must have a Group Control
Thermostat. 1 or 2 groups can be
used per wiring centre. HW Timer
can be stand alone or part of a
group. If using HW Timer as part
of a group it must be in Group 1.
