Introduction. Thank you for purchasingone of our Speedfit Aura 230V Thermostatmodels. To use all of the Thermostatfeatures, the optional communicationscables is required.

The unit can be configured to be aProgrammable Room Thermostat (PRT),Group Control Thermostat, GroupThermostat or Hot Water Timer.Communication between neighbouringJGSTAT2 and JGSTAT1 Dial Thermostats ispossible via the JGWC Wiring Centre(pictured below) and the optionalcommunications cables. More informationcan be found on pages 9 and 10.

Safety Information. Use inaccordance with the regulations.The Aura JGSTAT2 is to be usedfor room control of heating andhot water systems insidebuildings.

Product Compliance. Thisproduct is CE compliant andmeets the following ECDirectives: RoHS2 2011/65/EU, Electro-Magnetic Compatibility directive2004/108/EC and Low voltagedirective 2006/95/EC.

Product Compliance & Safety Information

Emergency. Switch off the voltageto the individual thermostat, wiringcentre or complete system.

Sources of danger. Thethermostat must be disconnectedfrom mains supply before removingthe cover.

For the installer. Please enterany parameter changes in theInstaller Notes section (pages 72- 75).

Installer parametersettings. The Aura JGSTAT2is equipped with an InstallerParameter section (see page40). This must only be enteredby the installer or a competentperson. Changing theseparameters can have a seriouseffect on your heating system.

SYSTEM

OVERVIEW

Programmable Room Thermostat (PRT). When configured for PRT (see page 31) theProgrammable Room Thermostat mainly works by itself and allows the user to have separateTime and Temperature control of each zone on the wiring centre. Features like Holiday, Party andFrost mode have to be set on each individual thermostat. The PRT can be configured for globalheat/cool system changeover if your system supports this. This is achieved from a switched inputfrom 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 amaximum of 2 groups per 8 zone wiring centre. Permanent temperature override, Holiday, Partyand Frost modes can be selected centrally from the Group Control Thermostat. Holiday modewill also be applied to a timer if applicable. Communication connections (see page 13) arerequired for grouping the Group Thermostats. Thermostats can be also globally changed fromheating to cooling thermostats if your system supports this by using the switched inputconnection on the JGWC (see the Wiring Centre Instruction Manual) along with theCommunications connections mentioned above.

Group Thermostat.When configured as a Group Thermostat (see page 36), the unit will followthe time schedule and override modes of the Group Control Thermostat. The Group Thermostatcan have its own programmed temperatures, Manual Override and also be removed from thegroup 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 withouttemperature control. In this configuration, the unit can be used as a Hot Water Timer. The Timerwill also follow a Group Control Thermostat when Holiday mode has been activated (requirescommunication connections).


System Overview - Configuration Options

Power and Switching cable – used topower thermostats and drive output.

Grouping and Communication cable.

Communication cable can be used when units are used as individual PRT's forheat/cool changeover. Please refer to page 13 and the Wiring CentreInstruction Manual.

While the units can function as standalone PRTs orTimers, installing this optional inexpensiveCommunication cable allows the units to communicatewith each other. This allows a thermostat to assumeconvenient remote control of a group. This bringscentral control of features such as Time Control,Holiday and Party functions as well as Frost Control.The individual group members can leave or re-entergroup control at the push of a button.

Cable size 1.5mm 3 core for L,N,SL and 0.5mm twin for the communication.
