TPG EWC-1 and EWC-2 wiring-centre May 2014
1
A wiring centre range with built in isolating switch allows access to thermostats and actuators
safely, without isolating the whole electrical circuit. The status of system zones can be seen
immediately, with call for heat LED lights on the front face of the centre. A power, boiler and
e facility to connect up to �ve
actuators per zone. Fully integrated earth connection, which will facilitate all earth connections to
ensure earth continuity .
EWC-1 Wiring Centres
-1 is now available. The
ays, 8 zone and 12 zone models.
Includes a fully integrated earth connection, which will facilitate all earth connections to ensure
earth continuity. Incorporates boiler/pump on LED to identify when the system is calling for heat.

EWC-1 Hard-wired wiring centres with on-off switch
230V and 24V 8-way wiring centres specially designed for radiant heating and cooling
applications
adding new thermostats or electrothermic heads to the
the whole electrical system
with a single time switch
Earth continuity terminals are integrated as standard, to
facilitate earthing requirements of system components to be
connected to the wiring centre
simple to connect a manifold pump to the centre
Separate boiler interlock terminals enable the boiler to be �red
The status of the system can be monitored with the LED’s on
almost all hardwired applications for both radiant heating and cooling.

Technical Data
On 24V models, note that when a 230V timeswitch is connected to the wiring centre, the wiring centre switch will not isolate
There is a 2.5 minute time delay following a call for heat before the pump is energised
Wiring centres feature independent boiler and pump interlock relays,
8 zone connections (with loose terminal connections to enable up to
�ve actuators to connect to each zone), on-off switch to enable safe
working inside the wiring centre and to thermostat and actuator
connections. Each circuit has an LED call for heat indicator. The
centre includes connections for an external timeswitch to allow
night set back operation for suitable thermostats, and includes a fully
integrated earth connection.
The 24V version incorporates a 50VA transformer with capacity for
up to 15 x 3W actuators. Both versions offer IP44 protection to
enable siting inside a manifold cabinet.
* Additional loose cap terminals can be obtained, code U9360030.
