INTRODUCTION

A programmable thermostat is a device that combines the

functions of both a room thermostat and heating controller

into a single unit. The programmable thermostat is used to

switch the heating system by means of time and

temperature change. This unit is not like a standard

programmer. It works by controlling the temperature

according to a series of programmed time and temperature

settings that take effect at different times of the day.

The ST620 from Salus Controls is a stylish and accurate 5/2

or 7 day programmable electronic thermostat with a large,

easy to read Liquid Crystal Display (LCD). This

programmable thermostat has been specifically designed to

be used Volt Free.

The use of the revolutionary Touch Ring technology makes for simple usage, and is coupled with a

unique, smart design. The LCD display will show the current room temperature and the ‘one touch’

operation makes the ST620 easy to operate.

• Volt Free Contacts

• Battery Powered with Replacement Indicator

INSTALLATION

Please read the important safety information at the start of this manual before you start to install the device.

The ideal position to locate the ST620 thermostat is about 1.5m above floor level. It should be mounted in a

location where the thermostat is accessible, reasonably lit and free from extremes of temperature and draughts.

Do not mount the thermostat on an outside wall, above a radiator or in a location where it may be subjected

to direct sunlight.

To ensure trouble free reception for the Radio Controlled Clock (RCC),

always ensure that the programmable thermostat is mounted away

from any possible sources of interference (such as radios, TV sets,

computers, etc.), and is not mounted on or in close proximity to large

metal objects. Installing the ST620 in enclosed areas such as cellars and

basements is not recommended. There are only two electrical

connections required to the ST620, and these connections should be

made to the terminal block inside the programmable thermostat. No

Earth connection is required for the correct and safe operation of the

ST620, but a parking terminal is provided to connect an Earth wire if

one is present. These connections are shown in the drawing and table below:

Terminal Function

L (COM) Live

SL (NO) Switched Live (output)

Earth Earth Parking (No electrical connection)

NOTE: All electrical installation work should be carried out by a suitably qualified Electrician or other

competent person.

If you are not sure how to install this programmable thermostat consult either with a qualified

electrician, heating engineer or your boiler / heating system supplier for advice on how to continue.

INSTALLING AND REPLACING BATTERIES

Installing or replacing the ST620 batteries is a straightforward operation, but does require you to

open the case of the programmable thermostat - always isolate the AC Mains supply before

opening the unit.

To open the ST620 case, undo the securing screw on

the bottom of the case (just to the right of the hole

for the Reset Button):

After undoing the screw pull it forward until the

screw stops moving, then carefully separate the

two halves of the case by gently pulling in an

upwards direction. Once the case has been

separated, the batteries should be visible:

Ensure that the batteries are inserted correctly, paying careful attention to the polarity markings on

the battery and next to the battery holders. After inserting the batteries, refit the ST620 case and

retighten the securing screw.

AFTER INSTALLATION

After completing installation and powering up the ST620 for the first time the programmable

thermostat will behave in the following way:

All the indicators on the display and the backlight will be turned on.

After 2 seconds the ST620 will then operate in NORMAL mode

and display the current room temperature, with the RCC

indicator flashing.

All programmable thermostat settings will be returned to default values.

If the Reset Button is pressed, the ST620 will behave in the same way as described above, except

that any previously saved user settings stored in the internal memory will be deleted and overwritten

with the default settings.

USER INTERFACE AND CONTROLS

The status and operation of the ST620 is clearly

shown on the large backlit Liquid Crystal Display (LCD).

This display allows the user to see at a glance the current

status of the heating system, as well as a clear indication

of the current room temperature.

The display consists of a combination of symbols and alphanumeric displays. The top row is a time

and day of the week indicator, the centre row is used to indicate temperature (in Celsius), and the

bottom row is an alphanumeric display for menu and status messages. The symbols around the outside

of the display are status indicators – an explanation of what these indicators mean is shown below.

OPERATION

The ST620 is configured and adjusted by the use of an

innovative and stylish Touch Ring, and two touch sensitive

buttons. The Touch Ring surrounds the programmable

thermostat display, and is operated very easily by moving

your finger around the ring.

The backlit Liquid Crystal Display (LCD) gives a highly visible,

easily readable indication of the thermostat status.

ACCESSING THE MENUS

The Arrow key is not active when the ST620 is in NORMAL mode. To access

the Menu screens, press the OK key twice. The first menu displayed is the

PROGRAMME menu:

Use the Touch Ring to scroll through

the Menus, and press the OK key to

select the menu you want to use:

You can scroll through the menus in

either direction (forwards or

backwards) depending on the

direction you move your finger

around the Touch Ring. The menus

are displayed in the order shown in

the picture above.

Pressing and holding the Arrow key for 2 seconds will return the ST620 to NORMAL mode. The

programmable thermostat will also return to NORMAL mode after 10 seconds if no Key is pressed or
