INSTALLATION
Power supply:
EGR-1 is to be installed into a fuse box (or other electrically safe place). Use either 230 VAC (orange
terminals) or 12 V DC (black terminals) as power supply,
but
not both
at the same time
! Adjust
the protection lid over the 230V terminal strips once all connections are made.
Antenna:
The radio antenna is stripped along 16 cm on one end, which must stick vertically out of the fuse
box. Connect the central lead wire to the ANT terminal, and the other one to GND (cf. Fig. 2).

Temperature sensor:
If thermostatic regulation or temperature reading is required, connect a temperature sensor to
inputs T1 and GND.
The temperature sensor cable must not be laid out alongside 230V leads and should be kept as far
away as possible from any sources of electrical interferences. Thermostatic regulation and
temperature reading may otherwise be perturbed. The temperature sensor should therefore not be
used as a floor sensor for floor heating installations, as this would require shielded twisted pair
sensors and filters. Similarly, whereas it is possible to extend a temperature sensor, it would also
induce a loss of precision of measurements.
Output relay:
The potential-free relay is for controlling other appliances; it supports a load of 16 A. It offers
thermostatic regulation and on/off control.
NB!
When using a 230 VAC power supply, the voltage applied at the relay must also be 230 VAC.
Conversely, a power supply of 12V DC limits the use of the relay to extra-low voltages (12V DC
or less). Add auxiliary relays or contactors when necessary.
