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 RT310RF from SALUS Controls is a stylish and
accurate digital thermostat with an easy to read Liquid
Crystal Display (LCD).

The Receiver is used for wiring connections and heat on/
off control. The thermostat provides the user interface
and temperature sensing / control. The two units are
linked together by a Radio Frequency (RF) signal.

Installation

Note: Please insert batteries into the RT310RF thermostat and it will power up..

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.

Test Pairing Function

Make sure your devices are wired and the thermostat has batteries inserted. Switch receiver to ON. If you are
using the RT310RF pack, the pairing between the thermostat and the receiver is already done. If you bought
the RT310TX and RXRT510 separately then pair as follows. Please make sure that the Receiver is set on Auto.

Note: Before beginning the process, switch the receiver On/Off and then On again to reset it (On/Off/On).

Testing the RF transmissions

It is important to site both the Receiver and thermostat in locations where the RF signal cannot be interrupted.
The receiving range between the thermostat and Receiver is approximately 30 metres indoors, however many factors can
affect the RF transmission and shorten the operating distance, e.g. shielding by thick walls, foil back plasterboard, metal
objects such as filing cabinets, general RF interference, and so on. The range is generally large enough for most household
applications, but it is advisable to test the RF transmission from the intended thermostat location to the Receiver location
before fixing the thermostat to the wall.

To check the RF reception, follow the following steps:

1. Press the UP button on the thermostat until the set point temperature is higher than room temperature by a few
degrees.

2. Wait for a few seconds. The Heat on (heat call) indicator should appear on the bottom left of the LCD on the thermostat.

3. Check the green LED on the receiver unit - it should be lit.

4. Press the DOWN button to adjust the set point temperature to be lower than room temperature.

5. Wait for a few seconds, and the Heat on (heat call) indicator should disappear and the green LED should switch off.

6. If at step 3 the green LED is not illuminated, press the TEST/PAIRING button on the thermostat and try to place the
thermostat closer to the Receiver.

7. Repeat steps 1 to 5.

Adjusting setpoint

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 RT310RF will return to Normal mode if no keys are pressed for more than 2 seconds. Once the new control
has been implemented, the change is permanent override until new Setpoint is set again. Setpoint temperature
cannot be changed if Frost Protection mode is enabled.
