General
The RXPW1 can only be used
in the PLX05 electronic range
of heaters.
They offer either individual
programming (each individual
heater has a programming
module) or group programming
from a master heater through
the pilot wire. Group
programming can drive up to
10 slave heaters.
Two heating positions are offered: comfort and off, with
temperatures set using the controls on the heater.
For default Screen see
Fig. 1
.
Installation
The RXPW1 is rated at 230V.
1.
Switch the heater off.
2.
Using a narrow bladed screwdriver, carefully release
the cover from the slot on right hand side of the
thermostat on the Panel Heater.
3.
Remove the 7-day plug in timer from it’s box and plug
it into the slide in compartment now exposed - see
Fig.

. Insert the programmer fully so that it clicks into
position. Switch the heater back on at the mains supply.
Individual Programming
Fit one programmer to each EPX heater. (Note: When the
heater is installed, the black pilot wire in the mains supply
cable should be trimmed back in accordance with the
Installation Instructions.
Programming for a Zone
The heater containing the RXPW1 is the Master heater and
connected by the black pilot wire to the Slave heaters. The
Master heater determines the Program and heating levels for
all the heaters (Comfort and Off), but the actual comfort
temperature should still be set on each individual heater (see
EPX Panel Heater instructions). The master heater will switch
between Comfort and Off according to the program.
Electrical Connection Master/Slave Heaters
DO NOT connect the
BLACK (PILOT) SIGNAL WIRE
to earth.
When the programmer drives other heaters, connect the pilot
wire from the ‘MASTER’ unit to the pilot wire of a ‘SLAVE’
heater and then from one ‘SLAVE’ heater to another (in series)
- see
Fig. 3

Any 240V insulated cable may be used to link pilot wires
around the ring main. The signal current is low. Suitable
connections would be either an additional single core wire
marked or colour coded appropriately or use a 4 core cable
throughout the heater ring.
Operating Instructions
The RXPW1 can be programmed either inserted directly into
the heater or out of the heater. If choosing the latter option,
the cassette must be first left in the heater for 2 days to charge
