DESCRIPTION
RAYSTAT-ECO-10 is an electronic controller with display, advanced alarm
facilities and the capability of switching large currents.
The RAYSTAT-ECO-10 is designed to control heating cable systems.
Heating cable can be controlled either directly by the RAYSTAT-ECO-10 or
via a contactor.
Direct switching of heating cables is possible for heating loads up to 25 A.
For heating loads greater than 25 A indirect switching via a suitably rated
contactor controlled by a RAYSTAT-ECO-10 is necessary. Installation
and all wiring must be in accordance with applicable regulations. The
device must be installed in non hazardous areas only. Pentair Thermal
Management offers other controls for use in hazardous areas.

Type: 3-wire Pt 100 according to IEC Class B
Sensor head: 50 mm x Ø 6 mm
* An external Pt 100 sensor can be connected, the sensor cable can be
extended with a 3-core shielded cable of 20 Ω max. per conductor (e.g. up
to 150 m with a 3 x 1.5 mm² cable)
FUNCTIONAL DESCRIPTION
The Raystat-ECO-10 Controller is used to control heat-tracing freeze
protection systems based on ambient temperature. The controller adjusts
the power of the heating cable by energizing the circuit for a percentage
of a complete cycle. This percentage is determined based on the
ambient temperature, the set point, and the minimum expected ambient
temperature. The full cycle time is influenced by pipe diameter.
For example, if the ambient temperature is halfway between the
minimum expected ambient temperature and the set point, the heating
cable will be energized for 5 minutes and be off for 5 minutes (for the
smallest pipe size selected). The actual duty-cycle periods and ratios
vary, depending on the ambient temperature and the above mentioned
parameters. This algorithm is called Proportional Ambient Sensing
Control (PASC).
If you are unsure about the min. expected ambient setting, set it to a
higher rather than a lower value to prevent freeze-ups.
In the event of an error, the alarm relay switches and an error code shows
on the display. It is possible to program the status of the heating cable
(ON or OFF) in case of a sensor error.
The unit is fitted with a battery so that programming can be done on
the bench prior to mounting in the working location (see Operational
description, page 11).
DISPLAY
RAYSTAT-ECO-10 has a digital display. The three left hand digits 9a are
the value display and the right hand digit 9b is the status display.

8
There are 4 different display modes possible:
1. In the normal operation mode (no error condition), the measured
temperature or the set point temperature value are displayed in the
value display (alternating).
During the time that the actual measured temperatures is shown,
the TA LED in the status display lights up. At the moment that the set
point temperature is shown, the WT LED in the status display lights up.
Also during normal operation, the middle horizontal LED in the status
display lights up when the PASC algorithm is active.For example:
means –5°C measured temperature and PASC is active;
means set point temperature 5°C and PASC is active.
2. In case an error is detected, the value display shows “ ” (flashing)
and the status display indicates the error number (see Errors).
3. Programming is done by means of the push buttons (see Operational
description). In the programming mode, the status display will indicate
the code of the parameter that is selected. The value display indicates
the value for the parameter.
4. When power is initially applied, all display segments will illuminate for
a short period. This will also occur if no mains power is available and
the battery button is pressed. Do not push the battery button when the
unit is powered, as this will shorten battery life.
INSTALLATION DESCRIPTION
1. Installation of heating cable
For design and selection of heating cables in sanitary applications, follow
the Technical Handbook.
For selection of industrial heating cables, follow the Selection Guide for
Industrial Trace-Heating Systems or use the latest version of TraceCalc
or contact Pentair Thermal Management.
Follow the design guidelines and install the system in accordance with
the system specifications.
Follow the “Product Safety Notice” supplied with the heating cable.
Residual current device (RCD 30 mA) is required.
The RAYSTAT-ECO-10 is a sensitive electronic device, and should be
installed taking care of common guidelines for EMC interference.

2. Mounting of the enclosure
The RAYSTAT-ECO-10 can be installed indoor or outdoor.
Do not install the thermostat under the thermal insulation.
A. Wall mounting
Mount the enclosure using wall fasteners (screws) via the four, 4
mm Ø holes.
B. Mounting on a pipe
Pentair Thermal Management offers different support brackets
(not included) to mount the RAYSTAT-ECO-10 on a pipe: SB-100 or
SB-101.
3. Wiring
Remove the terminal protection cover to access the terminals.
Power cable
Enter a single phase (230 Vac.) power cable through the M25 gland 2
(see drawing A ) and wire according to the wiring diagram (page 33).
Wiring the heating cable can be done either:
A. Via junction box or contactor or when using RayClic with the cold
cable through the M25 gland 3 .
B. Directly into RAYSTAT-ECO-10.
In this case, the M25 gland 3 , which is delivered pre-mounted to
the RAYSTAT-ECO-10, is to be replaced by an appropriate kit.
Follow instructions supplied with the kit for installation.
Important: For Voltage Free Operation, the wire links (W1) and (W2) need
to be removed. Failure to remove the wire links can result in damage to
the unit or to other connected equipment. Wiring of RAYSTAT-ECO-10 to
a remote alarm is optional through the M20 gland 4 . Pentair Thermal
Management strongly recommends the use of a remote alarm for critical
operations (e.g. when extreme low temperatures (lower than –25°C) can
be expected or for critical processes).

4. Installation of the sensor
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
surfaces 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
section of 3 x 1.5 mm² is used (max. 20 Ω per conductor).
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.
Close the lid of the unit.
