Introduction

A room thermostat simply switches the heating system on and off as necessary. It works by sensing the air
temperature, switching on the heating when the air temperature falls below the thermostat setting, and
switching it off once this set temperature has been reached.

Turning a room thermostat to a higher setting will not make the room heat up any faster. How quickly the room
heats up depends on the design of the heating system, for example, the size of boiler and radiators. Neither
does the setting affect how quickly the room cools down. Turning a room thermostat to a lower setting will
result in the room being controlled at a lower temperature, and saves energy.

The heating system will not work if a time switch or programmer has switched it off.

The way to set and use your room thermostat is to find the lowest temperature setting that you are comfortable
with, and then leave it alone to do its job. The best way to do this is to set the room thermostat to a low
temperature – say 18⁰C – and then turn it up by one degree each day until you are comfortable with the
temperature.

You won’t have to adjust the thermostat further. Any adjustment above this setting will waste energy and cost
you more money.

If your heating system is a boiler with radiators, there will usually be only one room thermostat to control the
whole house. But you can have different temperatures in individual rooms by installing thermostatic radiator
valves (TRVs) on individual radiators. If you don’t have TRVs, you should choose a temperature that is reasonable
for the whole house. If you do have TRVs, you can choose a slightly higher setting to make sure that even the
coldest room is comfortable, then prevent any overheating in other rooms by adjusting the TRVs.

Room thermostats need a free flow of air to sense the temperature, so they must not be covered by curtains
or blocked by furniture. Nearby electric fires, televisions, wall or table lamps may prevent the thermostat from
working properly.

Features

The RT310from SALUS Controls is a stylish and accurate
digital thermostat with an easy to read Liquid Crystal Display
(LCD).

Features

• Frost protection(selectable)

• Low-Battery Warning

• Low-Battery Detection

• Modern Casing

• Sleep Mode

• User Friendly

Installation

The ideal position to locate the RT310 thermostat
is about 1.5m above floor level, 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. The electrical connections to
the RT310 are made to the supplied industry
standard backplate. This simplifies installation, as
no connections are made to the controller itself.
Connection details are shown below - no Earth
connection is required for the correct and safe
operation of the RT310, but a parking terminal is
provided to connect an Earth wire if one is present.

DIP switch settings

The DIP switches are found on the rear of your thermostat and can be used to change the span (temperature
accuracy) of your thermostat from the default +/-0.5°C to +/-0.25°C. This may cause your boiler to operate more
frequently. The DIP switches are located on the back of the thermostat. ON +/-0.25°C, OFF +/-0.5°C.
The span is the accuracy with which the thermostat operates when displaying your temperature. You can
increase the accuracy by setting the span to +/-0.25°C, meaning that your thermostat will be sensitive to a
quarter of a degree temperature change and will activate/deactivate the boiler.

Note: You can also use a flush mount housing and a German and UK wall box to mount the thermostat directly
into the wall. The standard wall box has a diameter max 60mm and depth from 41-46 mm. The cable entry on
the backplate must allow a cable with 5*1,5 mm

shown. The typical reset display is shown below.

The following table shows the settings of the RT310 digital thermostat after RESET button is pressed:

Function Status after Reset
Operation Mode Normal mode
Room Temperature 22.0°C, to be renewed within 5 seconds
Setpoint Temperature 20.0°C
°C indicator On
Frost Protection indicator Off
Heat indicator Off
Low-Battery Warning indicator Off, to be renewed within 5 seconds

Adjusting Setpoint Temperature

By changing the Setpoint temperature, you are permanently altering your temperature. You can change the
set point temperature very easily while you are reviewing the set point temperature. Press the UP or DOWN
keys repeatedly to change the temperature setting. The set point temperature will flash to indicate that it can
be changed: the temperature will be changed in 0.5°C steps per key press.
The RT310 will return to Normal mode if no keys are pressed for more than 2 seconds. Once the new Setpoint
is implemented, the change is permanently overridden until a new Setpoint is set again. Setpoint temperature
cannot be changed if Frost Protection mode is enabled.
