There are 4 different display modes possible:

1. In the normal operation mode (no error condition), the measured tem-

perature or the set point temperature value are displayed in the value dis-

play (alternating).

During the time that the actual measured temperatures is shown, the T

LED in the status display lights up.

At the moment that the set point temperature is shown, the W

status display lights up.

Also during normal operation, the middle horizontal LED in the status dis-

play 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 "

and the status display indicates the error number (see Errors).

3. Programming is done by means of the push buttons (see Operational de-

scription). 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 In-

dustrial Trace-Heating Systems or use the latest version of TraceCalc or con-

tact Tyco Thermal Controls.

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 ∅

LED in the

holes.

B. Mounting on a pipe

Tyco Thermal Controls 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 . Tyco Thermal Controls strongly

recommends the use of a remote alarm for critical operations (e.g. when ex-

treme low temperatures (lower than –25°C) can be expected or for critical

processes).
