Wiring Diagram and Instruction Manual
JGWC - 230v 8 Zone Wiring Centre
Hot Water Connections
Option 2 - Connect Cylinder Thermostat directly to
Hot Water Timer. A link will be needed between IN and
OUT on the wiring centre as shown by the arrow.
Option 1 - Connect Cylinder Thermostat
to wiring centre.
Dip Switch Set Up
Ribbon Connection
Actuator Connections
In order for the wiring centre to be able to control UFH and
Radiators, there is a need to turn off the UFH pump for a
zone when that zone is to be used for radiators.
This must be carefully removed or replaced when removing or replacing the wiring centre
cover, being careful to ensure the correct orientation.
Actuator connections corresponding to the thermostat connections. Up to 2 cables can
be used in each connection (4 Actuators per Zone). If more than that number needs to be
connected, then an external junction box will be needed. A maximum of 6 actuators can
be connected to a zone in this manner.
Example: When fitting a zone for radiators or towel rail then
the Dip Switch for that zone should be switched to OFF.
The Dip Switches for this are located under the front lid.
When the zone switch is in the ON position the UFH
pump will run when that zone is calling for heat along with
the boiler. When it is in the OFF position then the UFH
pump will not run but the boiler will fire.

Please Note: When using option 2 refer to Device Parameters on pages 40 - 42 of the
230v Thermostat Instruction Manual.
Motorised Valves, Pump, Boiler & Thermostat Connections
Thermostat Grouping
Thermostat Zones
Cylinder Thermostat (Optional): If connecting the cylinder thermostat directly to the timer then a
link needs to be fitted between IN and OUT on the HW Cylinder thermostat connection.
The thermostats can work as individual units or in groups. There can be up to 2 groups of thermostats
per wiring centre. In order to work in groups the communications cable must be connected to the
wiring centre communications terminals (+ & -). The (-) terminals are common to all thermostats. In
order to assign the thermostat to group 1 or 2 then the communications cable + must be connected
to the relevant 1 or 2 + terminal.
Hot Water Motorised Valve (Optional): Used if timed hot water is required.
Overheat Thermostat (Optional): Used for connecting a pipe thermostat to prevent over
temperature water damaging sensitive floors. Remove the link and connect the pipe thermostat so it
is Normally Closed. The pipe stat will open if overheating occurs and the UFH pump will stop running.
OPTIONAL COMMUNICATIONS
CABLE 0.5MM
Boiler Enable (Optional): This Volt Free connection must come from the boiler thermostat
connection. When any zone calls for heat the boiler enable will close causing the boiler to run. If work
is being carried out on the boiler then power to and from the switch will cease. (Do not connect to the
boiler IN terminal by linking a 230V feed from the wiring centre).
UFH Motorised Valve (Optional): If a UFH motorised valve is fitted then remove the link between
OR and GR.
Heat/Cool Changeover (Optional): This connection allows heat/cool changeover of all
thermostats using a single external switch (installer supplied).
