Product Compliance & Safety Information

Introduction. Thank you for purchasing one of our Speedfit Aura 230V Thermostat models. To use all of the Thermostat features, optional communications cables are required. The unit can be configured to be a Programmable Room Thermostat (PRT), Group Control Thermostat, Group Thermostat, or Hot Water Timer. Communication between neighboring 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.

Product Compliance. This product is CE-compliant and meets the following EC Directives: RoHS2 2011/65/EU, Electro-Magnetic Compatibility directive 2004/108/EC and Low voltage directive 2006/95/EC. 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. We hope you enjoy this product…These instructions are applicable to the Speedfit Aura model stated on the front cover of this Instruction Manual only.

Warning. This product must be fitted by a competent person. Installation must comply with the guidance, standards, and regulations applicable to the location where the product is installed. Failure to comply with the requirements of the relevant guidance, standards, and regulations could lead to injury, death, or prosecution. Sources of danger. The thermostat must be disconnected from the main supply before removing the cover. Emergency. Switch off the voltage to the individual thermostat, wiring center, or complete system.

230v AC
Warning. Always isolate the AC Mains supply before installing or working on any components that require 230v AC 50Hz supply. Installer parameter settings. The Aura JGSTAT2 is equipped with an Installer Parameter section (see page 40). This must only be entered by the installer or a competent person. Changing these parameters can have a serious effect on your heating system. For the installer. Please enter any parameter changes in the Installer Notes section (pages 72

System Overview – Configuration Options

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 center. Features like Holiday, Party, and Frost modes 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 the 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 center. 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).

System Overview – Cables

• Power and Switching cable – used to power thermostats and drive output.
• Grouping and Communication cable.
• 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.
• Communication cables can be used when units are used as individual PRTs for heat/cool changeover. Please refer to page 13 and the Wiring Centre Instruction Manual.
• Cable size 1.5mm 3 core for L, N, SL and 0.5mm twin for the communication.

System Overview – Options
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 center. 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.

Option 1 – Page 09.
The unit is configured as an individual PRT.

Option 2 – Page 10.
Unit is configured as a Group Control Thermostat used to control a group(s) of unit(s) configured as Group Thermostats.

Option 3 – Page 10.
Unit is configured as a Group Control Thermostat used to control a group(s) of Digital Stat(s) configured as Group Thermostats.

Option 1 – Page 31.
All thermostats are set as PRT.

Note: The communication connection is only used for heat/cool changeover when using units configured to PRTs and using the relevant connection on the JGWC Wiring Centre. Please refer to the Wiring Centre Instruction Manual.

Option 2 – Page 33 Option 3 – Page 35

Note: HW timer will only use HOLIDAY mode when the communication connection is used. Also, the HW Timer must be connected to GROUP 1 communication terminals on the Wiring Centre. Please see the Wiring Centre Instruction Manual.

System Overview – Hot Water Option

When the unit is configured as a Hot Water Timer (see page 34) there are two methods of connecting the cylinder thermostat.

Cylinder thermostat options:

1. Connected directly to JGWC (default).
2. Connected directly to JGSTAT2.

For convenience, there is a unique built-in option allowing the cylinder thermostat to be connected to either the HW Timer or Wiring Centre.

1. Connected directly to JGWC (default).
2. Connected direct to JGSTAT2 (requires additional parameter change see page 40). Please refer to the Wiring Centre Instruction Manual and page 18 for more information.

Installation – Terminal Connections
Understanding your terminal connections.

• Communication Terms 12v DC. Two wire twisted pairs can be used for Grouping Functions between Group Control Thermostat, Group Thermostat, and HW Timer.
• Sensor Terminals. Can be used for external AIR or Floor sensor when configured as a thermostat. Can also be used for cylinder thermostats when configured for HW.
• Power Terminals 230v AC. Used for supplying power to the unit and switched output.

Installation – Thermostat Mounting

Mounting position and installation. To ensure trouble-free operation and efficient control, the unit is best positioned in a draft-free area and 130cm from the floor. Do not position the thermostat near any heat source, behind curtains, in direct sunlight, or in an area of high humidity.

Not to be positioned on an exterior wall.

Installation – Thermostat External Sensor

Note: If you are using an External Sensor, the unit has to be configured for External Air Sensor or Floor Protection Sensor. Please see Device Parameter Setting on page 40.

Installation – Hot Water Timer Wiring

Installation – Hot Water Timer Cylinder Thermostat

Note: Optional – The JGSTAT2 can be configured for a connection to a cylinder thermostat. Please see Device Parameters on page 40. For additional wiring center information refer to the Wiring Centre Instruction Manual.
