Location of the sensor
Mount the sensor in a position exposed to normal weather conditions but
shielded from direct sunlight. The sensor should not be located against sur-
faces that are heated from within or may be heated by sunlight. If the
RAYSTAT-ECO-10 is located outdoors, the sensor cable may be shatened
and the sensor may be mounted directly to the bottom of the housing, but
make sure that at least 35 - 40 mm of the sensor extends beyond the gland
fitting and that the sensor is not in contact with other cables.
Warning: Do not install sensor at ambient temperatures below –20°C. Do
not bend sensor, keep it straight under all circumstances.
Wiring sensor to RAYSTAT-ECO-10
Enter the sensor cable through the indicated M16 gland 5 and wire as
shown in the wiring diagram (page 33). Please pay attention to color coding
of the wiring.
Remark: The sensor cable can be extended up to 150 m when a cross sec-
is used (max. 20 Ω per conductor).

tion of 3 x 1.5 mm
The connection between sensor cable and sensor extension can be made in
junction box JB-86 or equivalent. Use a shielded cable for extension to avoid
interference. The shielding braid is to be earthed in the thermostat.
5. Complete installation
Put the terminal protection cover back in place.
If RAYSTAT-ECO-10 is not yet programmed, please do so as described in
Operational description (page 11) and onwards.

Operational description
1. Introduction
The RAYSTAT-ECO-10 parameters are configured via a menu system.
The unit is delivered with a battery so that the operating parameters can be
set up without any need for the power supply to be connected. This is useful
for setting units on the bench prior to mounting in their working location or
on site when power isn't available.
Please note that the Battery key (
has the power supply connected. It will cause the battery to discharge imme-
diately. The battery will be disconnected automatically when the last para-
meter has been set.
Once programmed, the settings will be retained even in case of power loss.
2. Activating and navigating the Menu in Set-Up mode
In order to activate the Set-up mode when the unit is not connected to a
mains power supply, press the Battery key (
This action will immediately light up all segments of the display, so correct
functioning of the display can be verified. The display will then shortly show
, and switch to the first parameter to be changed.
In order to activate the Set-up mode when the unit is connected to a mains
power supply (the display alternates between the setpoint and actual meas-
ured temperature), press the MENU key for about 2 sec. The display will
shortly show
, and switch to the first parameter to be changed.
Stepping through the complete parameter list can be done by successively
pressing the MENU key. When the last parameter has been set, the display
will show
, and return to normal operation. In case the unit is not con-
nected to a power supply, the battery will be disconnected.
If the unit is in Set-up mode, but no keys are activated, it will return to the
normal operation (or switch the battery off when the battery is used) after
about 30 sec.
To alter any parameter shown in the display, press the + or – keys. This
will allow the parameter to be raised or lowered to the maximum or the mini-
mum in integer steps.
If you require to reset all parameters to their default value, press the + and
– keys together for about 2 sec. If this is succesful, the display will show
